Difference Between 24K, 22K, and 18K Gold — The Complete Guide for Buyers and Investors (2026)

Difference Between 24K, 22K, and 18K Gold— 24K vs 22K vs 18K gold: 24K gold is 99.99% pure gold — the highest purity available, best for investment, VAT-exempt in most markets, priced at approximately KES 18,200/gram (USD $139) in June 2026. 22K gold is 91.7% pure gold — the best balance of purity and durability for fine jewellery, priced at approximately KES 16,683/gram (USD $127).

18K gold is 75% pure gold — harder than 24K or 22K, ideal for everyday wear jewellery such as engagement rings and bracelets, priced at approximately KES 13,650/gram (USD $104). The higher the karat number, the purer, softer, more expensive, and more vivid yellow the gold is.

The lower the karat, the harder, cheaper, and more suitable for daily-wear jewellery. For investment: always choose 24K. For jewellery you will wear every day: 18K or 22K. Buy Gold Bars Kenya supplies all three purities with SGS-certified assay documentation. Visit buygoldbarskenya.com.

The question of “what is the difference between 24K, 22K, and 18K gold?” is the most important question any gold buyer — whether purchasing jewellery, investing in gold bars, or exporting gold internationally — needs to understand before spending a single shilling. Karat (K or kt) is the universal measure of gold purity on a 24-part scale.

24K means all 24 parts are gold — 99.99% pure. 22K means 22 parts are gold and 2 parts are alloy — 91.7% pure. 18K means 18 parts are gold and 6 parts are alloy — 75% pure.

The alloy metals (copper, silver, zinc, palladium, or nickel) are not impurities — they are deliberate additions that change the gold’s hardness, colour, and wearability for specific applications.

This guide covers everything you need to know about 24K vs 22K vs 18K gold — current prices per gram in Kenya (KES and USD), purity and composition, colour differences, hardness and wearability, investment value, VAT treatment, which karat is best for which purpose, and exactly where to buy certified gold bars and jewellery-grade gold in Kenya.

Buy Gold Bars Kenya is a KRA-registered, SGS-certified gold dealer in Westlands, Nairobi supplying all three purities with independent assay documentation and insured worldwide delivery. See our gold bars for sale for current stock and pricing.

What Karat Actually Means — Gold Purity Explained Simply

The word “karat” (abbreviated K or kt) measures gold purity on a scale of 24 parts. Think of a 24-gram gold bar — if it were 24K, all 24 grams would be pure gold. If it were 22K, 22 grams would be pure gold and 2 grams would be alloy metals. If it were 18K, 18 grams would be gold and 6 grams alloy. This part-in-24 system translates directly to percentage purity:

Karat	Parts Gold / 24	Purity %	International Fineness Mark	Hallmark Stamp
24K	24/24	99.99%	999 or 999.9	999 or FINE GOLD
22K	22/24	91.67%	916	916 or 22K
18K	18/24	75.00%	750	750 or 18K
14K	14/24	58.33%	585	585 or 14K
10K	10/24	41.67%	417	417 or 10K

The fineness mark (999.9, 916, 750) is the international standard — used by the LBMA in London, the DMCC in Dubai, the BIS in India, and on legally hallmarked jewellery worldwide.

When you see “750” stamped inside a ring or bracelet, it means 18K (75% pure gold). When you see “916” it means 22K (91.6% pure gold). When you see “999” or “999.9” it means 24K (99.99% pure gold).

⚠️ Important: Karat vs Carat “Karat” (K/kt) measures gold purity. “Carat” (ct/c) measures gemstone weight — 1 carat = 200 milligrams (0.2 grams), used for diamonds, rubies, and emeralds. These are completely different measurements. A “24-carat diamond” does not exist — a diamond’s carat refers to its weight, not its purity. A “24K gold ring” refers to the gold’s purity. Do not confuse the two.

24K Gold — The Purest Gold Available: Price, Properties, and When to Buy It

24K gold is 99.99% pure gold — the maximum purity achievable in commercial gold production. It contains no alloy metals in meaningful quantities, which gives it three defining characteristics that separate it from every other karat: the richest, most vivid yellow colour of any commercial gold product; the highest inherent value per gram (100% of the LBMA gold spot rate); and the greatest softness and malleability — making it unsuitable for most jewellery applications but perfect for investment bars, coins, and industrial uses.

24K Gold Price in Kenya — June 2026

The 24K gold price per gram in Kenya in June 2026 is approximately KES 18,200 (USD $139) — based on the LBMA gold spot of approximately $4,430 per troy ounce and a KES/USD exchange rate of approximately 131.

For the 1kg price (KES 18,200,000 / USD $138,932) and full historical price trend data, see our dedicated 1kg gold bullion price in Kenya page. The live gold price in Kenya today is updated continuously throughout the London trading session.

Why 24K Gold Is Too Soft for Everyday Jewellery

Pure gold has a Vickers hardness of approximately 25 HV — softer than most common metals you encounter daily, including copper (40–50 HV) and silver (25–35 HV).

In practical terms, this means a 24K gold ring worn daily will visibly scratch within the first week, lose defined design details within months, and physically deform under normal hand pressure within a year.

The malleability that makes 24K gold perfect for gold leaf, coin striking, and electronics is precisely what makes it a poor choice for a ring, bracelet, or watch case that must withstand daily contact with hard surfaces.

What 24K Gold Is Used For

Investment bars and bullion coins: The primary use — LBMA Good Delivery bars (400 troy oz), smaller retail bars (1g–1kg), and government-minted coins (Krugerrand, Maple Leaf, Britannia). Browse Buy Gold Bars Kenya’s 24K gold bars for sale.
Long-term wealth preservation: A 24K gold bar loses no gold content value from the moment of purchase to decades later. Its value tracks 100% of the LBMA spot price at all times.
Export gold for international delivery: All international gold export standards (LBMA, DMCC, COMEX) require 999.9 fine (24K) for Good Delivery. If you are buying gold from Kenya for export, 24K is the correct product.
Electronics and technology: Gold’s corrosion resistance and conductivity make 24K gold essential in circuit board contacts, semiconductor bonding wires, and satellite components.
Medical applications: Dental work, pacemaker electrodes, and cancer treatment nanoparticles use 24K gold for its biocompatibility.

VAT Treatment of 24K Gold in Kenya

Under Kenya’s VAT Act 2013, 24K investment gold bars (999.9 fine) are VAT-exempt — classified as financial instruments rather than consumer goods. This means a buyer purchasing a 24K gold bar from Buy Gold Bars Kenya pays no VAT on the transaction.

Gold jewellery products (including 22K and 18K) attract 16% VAT in Kenya. This VAT difference makes 24K investment bars significantly more tax-efficient for investors than jewellery-grade gold at any karat.

22K Gold — The Premier Jewellery Karat: Price, Properties, and Best Uses

22K gold (916 fine, 91.67% pure gold) is the most widely used gold purity for fine jewellery worldwide — particularly in India (the world’s largest jewellery market), the Middle East, and East Africa.

The 8.33% alloy content — primarily copper and silver — gives 22K gold a meaningfully higher hardness than 24K (approximately 90–120 Vickers vs 24K’s 25 HV) while retaining a gold content high enough to maintain the metal’s characteristic warm yellow lustre and intrinsic value.

22K Gold Price Per Gram in Kenya — June 2026

The 22K gold price per gram in Kenya in June 2026 is approximately KES 16,683 (USD $127) — exactly 91.67% of the 24K price, since 22K contains 91.67% of the gold content per gram that 24K contains. For the full 22K price history and current live rate see our live Kenya gold price page which shows all four major purities simultaneously.

22K Gold vs 24K Gold — The Key Differences

Purity: 22K = 91.67% gold vs 24K = 99.99% gold. The 8.32% difference in gold content means 22K always costs 8.32% less per gram than 24K at identical LBMA spot prices.
Hardness: 22K’s copper-silver alloy raises hardness from 24K’s 25 HV to approximately 90–120 HV — sufficient for jewellery that sees moderate daily wear. Still softer than 18K (120–200 HV).
Colour: 22K gold has a very rich yellow colour — marginally less vivid than pure 24K but richer than 18K yellow gold. The high gold content means the warm yellow tone dominates despite the alloy addition.
VAT in Kenya: 22K gold jewellery attracts 16% VAT, while 22K bars (if produced) are generally treated as VAT-exempt in the same way as 24K bars. However, 22K is not accepted as LBMA Good Delivery standard — it has lower international secondary market liquidity than 24K.
LBMA and export: 22K gold does not meet LBMA Good Delivery standard (which requires 999.5 fine minimum). For international export of investment-grade gold, 24K is required. 22K is primarily a jewellery product rather than an export commodity.

Who Should Buy 22K Gold

22K gold is the correct choice for:

Fine jewellery buyerswho want the highest possible gold content in wearable jewellery — particularly wedding jewellery, chains, and bangles
Indian and Middle Eastern jewellery marketswhere 22K (916 hallmark) is the culturally preferred standard for bridal gold
Hybrid investorswho want jewellery that also functions as a gold holding — the high 22K content means the resale gold value of well-made 22K pieces is relatively close to the purchase price, especially where making charges are low
Jewellery manufacturersimporting gold for production of high-purity wearable pieces. Buy Gold Bars Kenya supplies 22K gold for manufacturing applications through our services and wholesale supply page.

18K Gold — The Jewellery Industry Standard for Durability and Everyday Wear

18K gold (750 fine, 75% pure gold) is the gold standard for fine jewellery that must withstand daily wear — engagement rings, tennis bracelets, earrings, watches, and everyday necklaces.

The 25% alloy content (copper, silver, palladium, or nickel depending on the target colour) raises hardness to approximately 120–200 Vickers — four to eight times harder than 24K pure gold — making 18K rings and bracelets capable of surviving years of daily contact, scratching, and impact without visible deformation or loss of design detail.

18K Gold Price Per Gram in Kenya — June 2026

The 18K gold price per gram in Kenya in June 2026 is approximately KES 13,650 (USD $104) — exactly 75% of the 24K price, reflecting its 75% gold content. The price difference between 24K and 18K gold per gram in Kenya is approximately KES 4,550 (USD $35) per gram — which on a 100-gram jewellery purchase represents a difference of KES 455,000 (USD $3,500).

This significant price gap is why 18K is the dominant purity for fine jewellery retail globally — buyers get gold’s warmth and prestige at 75% of the pure gold price, plus superior durability. See all current prices at buygoldbarskenya.com/gold-price-in-kenya-today-per-gram/.

18K Gold Colours — Yellow, White, and Rose

Unlike 24K (which is always yellow) or 22K (which is always warm yellow), 18K gold is available in three distinct colours determined by the alloy composition:

18K Colour	Gold Content	Alloy Composition	Appearance	Most Common Uses
Yellow 18K	75%	12.5% silver + 12.5% copper	Classic warm yellow — richer than 14K, slightly paler than 22K	Wedding bands, classic jewellery, East African fine jewellery
White 18K	75%	25% palladium or nickel + rhodium plating	Silver-white, resembles platinum	Engagement rings, diamond settings, modern fine jewellery
Rose 18K	75%	22% copper + 3% silver	Warm rose-pink — fashionable and distinctly warm-toned	Fashion rings, contemporary pieces, popular globally since 2015

18K vs 24K — Is 18K Worth Buying?

For jewellery that you will wear daily — an engagement ring, a bracelet, a pair of earrings — 18K is not just acceptable, it is the superior choice to 24K for that specific purpose. A 24K engagement ring will deform within months of daily wear. An 18K engagement ring will last decades.

The 25% alloy content reduces the price per gram by 25% while making the piece dramatically more practical. Where 18K underperforms vs 24K is as a financial investment vehicle: 18K tracks only 75% of the LBMA spot price gain, attracts 16% VAT in Kenya as jewellery, and carries making charges that are not recovered on resale. For wealth preservation, always choose 24K bars.

24K, 22K, and 18K Gold Price Comparison in Kenya — Full Size Range (June 2026)

Which Karat Should You Buy? 24K, 22K, or 18K — A Decision Guide

The answer depends entirely on your purpose. The 24K vs 22K vs 18K decision is not about which karat is “best” in the abstract — each is best for a specific application:

Choose 24K Gold If You Are:

Investing for wealth preservation: 24K tracks 100% of the LBMA gold spot price. A 24K bar purchased today will be worth exactly the current LBMA-equivalent price ten years from now — no making charges, no deductions, no depreciation. Browse our 24K gold bars for sale at Buy Gold Bars Kenya.
Exporting gold internationally: LBMA Good Delivery, UAE DMCC, Swiss DFI, and most international gold market standards require 999.5 fine minimum (24K). If you are buying gold in Kenya for international delivery, only 24K meets these standards. See our export documentation and services.
Diversifying a financial portfolio: Gold ETFs, gold-backed financial instruments, and allocated vault storage programmes all price gold at 24K (999.9 fine) LBMA spot. Holding physical 24K gold gives you direct parity with these benchmarks.
Storing value over the long term: A 24K gold bar has no expiry date, requires no maintenance, and can be sold immediately to any licensed gold dealer worldwide. Its liquidity is superior to every other form of physical gold investment.

Choose 22K Gold If You Are:

Buying high-purity fine jewellery: 22K is the preferred jewellery standard for Indian, Middle Eastern, and East African bridal gold — offering 91.67% gold content in a form durable enough for occasional wear pieces like wedding bangles, heavy necklaces, and ceremonial chains
A jewellery manufacturer producing high-gold-content pieces: 22K allows higher gold content per piece than 18K while maintaining sufficient hardness for fabrication of rings, pendants, and chains. Contact Buy Gold Bars Kenya via our buying gold in Kenya guidefor wholesale 22K sourcing enquiries
A hybrid investor in a market that values jewellery resale: In markets like India, Dubai, and Kenya where jewellery is actively bought and resold by weight, well-made 22K pieces from reputable jewellers can be sold near their gold content value — particularly in periods of rising gold prices

Choose 18K Gold If You Are:

Buying everyday fine jewellery — particularly engagement rings: 18K is the correct choice for any ring intended for daily wear. Its hardness (120–200 HV) prevents the deformation and scratching that would rapidly degrade a 24K or 22K piece in the same application
Buying designer watches or complex jewellery pieces: Major watch brands (Rolex, Cartier, Patek Philippe) use 18K gold (usually yellow, white, or rose) for all their gold cases and bracelets — specifically because 18K withstands the mechanical stresses of daily watch wear that 22K or 24K would not
A fashion jewellery buyer seeking a lower price entry point: The 25% price reduction vs 24K gold means 18K is the most affordable entry point for genuine-gold fine jewellery while still containing 75% pure gold content
Buying in European and US markets where 18K is the dominant standard: In Western Europe, the UK, and the USA, 18K is the most widely used purity for fine jewellery retail. Local jewellery buyers are familiar with the 750 hallmark and 18K resale markets are well-developed

📊 Decision shortcut: Investment or export → buy 24K. Occasional-wear fine jewellery with high gold content → buy 22K. Daily-wear rings, watches, and bracelets → buy 18K. Never buy 24K gold jewellery for daily wear — it will deform and scratch too quickly to be practical regardless of how beautiful it looks in the display case.

Investment Value: 24K vs 22K vs 18K Gold — Which Holds Value Best?

For any buyer approaching gold as a financial investment rather than a jewellery purchase, the comparison between 24K, 22K, and 18K gold investment returns is straightforward — and 24K wins on every financial metric:

Gold price tracking: A 24K bar gains the full benefit of every LBMA spot price increase. A 22K bar gains 91.67% of that increase. An 18K bar gains 75%. Over the 214% LBMA gold price increase from January 2020 (≈$55/gram) to June 2026 (≈$139/gram), a 1kg 24K bar gained KES 10,921,200 in value. A 1kg 18K bar gained only KES 8,190,900 — a difference of KES 2,730,300 on a single kilogram from the same starting investment
Making charges — the hidden investment killer: Every piece of jewellery carries making charges — the labour cost of fabrication, typically KES 500–5,000 per gram in Kenya depending on complexity. These charges are not recoverable on resale, which values the piece at its metal content value (scrap price), not its retail price. A 22K or 18K jewellery piece purchased for KES 25,000/gram (including making charges and 16% VAT) may resell at KES 14,000–16,000/gram (scrap gold content value). A 24K bar purchased at KES 18,200/gram resells at KES 17,300–18,200/gram — a dramatically smaller bid-ask spread
VAT efficiency: In Kenya, 24K investment bars are VAT-exempt; 22K and 18K jewellery attracts 16% VAT. On a KES 1,000,000 jewellery purchase, KES 138,000 goes to VAT and is not recovered on resale. A KES 1,000,000 purchase of 24K bars attracts zero VAT — 100% of the capital is in gold
Resale liquidity: 24K gold (999.9 fine) is accepted without re-assaying by dealers worldwide. Any gold bullion dealer in Kenyawill buy 24K bars at near-spot price immediately. 22K and 18K jewellery must be physically assessed and may be discounted to 80–90% of gold content value depending on condition

How to Verify Gold Karat When Buying in Kenya — Testing Methods

When buying gold jewellery or bars in Kenya, knowing how to verify the stated karat before paying is an essential buyer protection skill. The following methods are available:

For Gold Bars — The Most Reliable Methods

Check the hallmark stamp: Every genuine gold bar from a licensed mint or refinery is stamped with its fineness (999.9, 916, 750) and a unique serial number. The stamp should be crisp and clearly defined — blurred or shallow stamps are a fraud indicator
SGS or Intertek independent assay certificate: The most authoritative verification — an independent laboratory certificate confirming purity, weight, and elemental composition. Buy Gold Bars Kenya provides an SGS Kenya or Intertek assay certificate with every gold bar purchase before payment is requested. See how we verify gold at our services page.
XRF (X-ray fluorescence) testing: A non-destructive surface elemental analysis that identifies gold content within seconds. Available at Buy Gold Bars Kenya’s Westlands showroom — buyers can observe the XRF test on their bars in person. Note: XRF only tests the surface layer; bars above 10g should also receive a density test
Density (Archimedes) test: The definitive anti-fraud test for gold bars. Measures the bar’s density in water and compares against pure gold’s known density of 19.32 g/cm³. Tungsten-filled fake bars show a significantly different density. Buy Gold Bars Kenya performs density testing on all bars at our Westlands showroom

For Gold Jewellery — Accessible Testing Options

Look for the hallmark: Genuine 18K jewellery should be stamped “750” or “18K” inside the piece. 22K should show “916” or “22K”. The absence of any hallmark on jewellery claiming to be gold is a significant warning sign
Electronic gold tester: A non-destructive conductivity test that estimates karat based on electrical resistance. Widely available at Nairobi jewellery shops and bullion dealers — quick, inexpensive, and sufficient for initial verification of jewellery
Acid test: A drop of nitric acid applied to a scratch mark on the gold surface — gold of each karat reacts differently to different acid concentrations. 24K pure gold shows no reaction; lower-karat pieces show progressively stronger reactions. A basic but effective screening tool for small jewellery items
