18K Gold Price: Today’s 18K Gold Price Per Gram, Ounce & Kilogram

The 18K gold price is determined primarily by the international gold spot price, the purity of the gold, currency exchange rates and the premium charged by a dealer, jeweller or gold refiner. Because 18K gold is 75% pure gold, its underlying metal value is lower than 22K or 24K gold of the same weight, but it remains one of the most popular gold purities for jewellery, watches and selected gold bars.

If you are searching for the 18K gold price today, 18K gold price per gram, 18K gold price per ounce, 18K gold price per kilogram, or the 18K gold rate in Africa, understanding how the price is calculated will help you avoid confusing the raw gold value with the final retail price.

Important: Gold prices change throughout the day. The figures below are reference calculations and published market examples rather than a guaranteed live buying quotation. For an exact transaction price, request a current quotation from a reputable dealer.

What Is 18K Gold?

18K gold, also called 18 karat gold or 18ct gold, contains 18 parts pure gold out of 24 parts total metal.

That means:

18 ÷ 24 = 75% pure gold

The remaining 25% consists of other metals such as copper, silver, zinc, palladium or other alloys. These metals make 18K gold harder and allow manufacturers to create different gold colours.

The international hallmark for 18K gold is commonly 750, meaning 750 parts per 1,000 are pure gold.

Gold purity	Fineness	Pure gold content
24K	999/999.9	99.9–99.99%
22K	916	91.6%
18K	750	75.0%
14K	585	58.5%
10K	417	41.7%

Our detailed guide to 18K gold purity, hallmarks and value explains why 750 and 18K represent the same 75% gold purity.

18K Gold Price Today

The 18K gold price today depends on where you are buying and whether you are looking at raw bullion value, jewellery prices or a finished gold product.

As a useful current market reference, a published Indian gold-rate report on August 24, 2026 listed 18K gold at approximately ₹122,930 per 10 grams, equivalent to about ₹12,293 per gram. The same report listed 24K gold at ₹163,970 per 10 grams and 22K gold at ₹150,300 per 10 grams.

That illustrates the basic relationship between purity and gold value.

For African markets, Buy Gold Bars Africa’s published 2026 pricing examples also demonstrate how the 18K price is derived from the 24K gold value. Its Uganda guide, for example, gives a published 18K reference of approximately UGX 402,570 per gram, or about $107–$112 per gram, based on the market data used in that guide.

Because gold prices and currencies move continuously, do not treat an old published price as a guaranteed buying or selling price.

18K Gold Price Per Gram

The 18K gold price per gram can be calculated from the 24K spot price using the gold purity.

The basic calculation is:

18K gold price per gram = 24K gold price per gram × 0.75

For example, if pure 24K gold is worth $150 per gram:

$150 × 75% = $112.50 per gram

Therefore, the theoretical metal value of 18K gold would be approximately $112.50 per gram, before dealer premiums, manufacturing charges, taxes, refining costs and other expenses.

This calculation is especially useful when you want to check whether a quoted 18K gold price per gram is reasonable.

Example 18K Gold Price Calculation

24K gold price	18K theoretical metal value
$100/g	$75/g
$120/g	$90/g
$140/g	$105/g
$150/g	$112.50/g
$160/g	$120/g
$170/g	$127.50/g
$200/g	$150/g

These are mathematical examples, not live dealer quotations.

How Much Is 18K Gold Worth Per Gram?

The answer depends on the current price of pure gold.

For every 1 gram of 18K gold, approximately 0.75 grams is pure gold.

So if the current 24K gold price were $150 per gram, the underlying gold content of 1 gram of 18K gold would be worth approximately $112.50.

But an actual jewellery item could sell for considerably more because the customer may also be paying for:

Design
Manufacturing
Labour
Brand
Stones
Retail overhead
VAT or sales taxes
Dealer margin
Packaging

Consequently, the 18K gold jewellery price is usually not the same as the raw 18K gold melt value.

18K Gold Price Per Ounce

Gold is internationally traded using the troy ounce, not the ordinary household ounce.

One troy ounce equals approximately 31.1035 grams.

Therefore, if 18K gold were worth $112.50 per gram based on its underlying metal content:

$112.50 × 31.1035 = approximately $3,499 per troy ounce

This demonstrates why the 18K gold price per ounce is normally lower than the price of a 24K troy ounce.

The actual price will change as the international gold market changes.

For authoritative international benchmark information, the LBMA Gold Price is an important reference used by the global precious-metals industry.

18K Gold Price Per Kilogram

A kilogram contains 1,000 grams.

Because 18K gold is 75% pure, one kilogram of 18K gold contains approximately:

1,000g × 75% = 750g of pure gold

Therefore:

18K gold price per kilogram = 24K gold price per gram × 750

For example, at a hypothetical pure-gold price of $150 per gram:

$150 × 750 = $112,500

So the theoretical metal value would be approximately $112,500 per kilogram of 18K gold.

A finished 18K jewellery product or commercially traded bar may have a different price because of premiums, refining, manufacturing, assay and other transaction costs.

18K Gold Price in Africa

The 18K gold price in Africa is not identical in every country. Local prices are affected by the international gold price, exchange rates, local supply, taxes, import/export requirements and dealer margins.

For example, Buy Gold Bars Africa’s published Kenya gold-rate table gives 18K gold at approximately KES 14,400–14,700 per gram, or around $111–$114 per gram, in the market data presented on its page.

Its Ghana gold-pricing guide gives a June 2026 reference of approximately GHS 1,174 per gram, equivalent to about $104.57 per gram, for 18K gold.

The difference between these figures does not necessarily mean that gold itself has a different intrinsic value. Currency conversion, market timing, premiums and local commercial conditions all influence the final quotation.

18K Gold Price in Uganda

Uganda is an important gold-trading and refining market in East Africa.

Buy Gold Bars Africa’s published Uganda guide gives the following 18K reference price:

Weight	Approximate 18K gold content	Published reference
1 gram	0.75g fine gold	UGX 402,570 / ~$107–$112
10 grams	7.5g fine gold	Calculated from per-gram value
100 grams	75g fine gold	Calculated from per-gram value
1 kilogram	750g fine gold	Calculated from per-gram value

These figures are based on the market conditions and exchange-rate information used by Buy Gold Bars Africa in its May 2026 guide and should be replaced with a live quotation when a transaction is being arranged.

If you are specifically interested in Uganda, see our detailed guide to gold bars in Uganda for information about gold bar sizes, purity and pricing.

18K Gold Price in Ghana

Ghana is one of Africa’s major gold-producing markets, and 18K gold in Ghana is commonly encountered in jewellery and other gold products.

Buy Gold Bars Africa’s June 2026 Ghana pricing guide lists 18K gold at approximately GHS 1,174 per gram, or $104.57 per gram, with a 10g reference of approximately GHS 11,740 or $1,045.70.

The same guide shows how the value changes according to purity:

Purity	Fineness	Published Ghana reference
24K	999	~$139.39/g
22K	916	~$127.78/g
18K	750	~$104.57/g

These figures are useful for illustrating the relationship between gold purity and price, but a live quotation should always be requested before purchasing.

18K Gold vs 24K Gold

One of the most common searches is 18K gold vs 24K gold.

The main difference is purity.

24K gold is nearly pure gold, while 18K gold contains 75% pure gold and 25% alloy metals.

Feature	18K Gold	24K Gold
Purity	75%	99.9–99.99%
Hallmark	750	999/999.9
Durability	Higher	Softer
Jewellery use	Very common	Common for high-purity jewellery
Investment bullion	Less common	Preferred
Colour options	Yellow, white, rose	Primarily rich yellow
Fine gold in 10g	7.5g	~9.999g

If your objective is primarily investment gold, 24K bullion generally provides more fine gold for the same gross weight.

If your objective is jewellery that balances gold content with durability, 18K gold can be an attractive choice.

Our guide to gold bar sizes and prices can help you compare different bullion denominations.

18K Gold vs 22K Gold

The 18K vs 22K gold price difference comes directly from the amount of pure gold contained in each gram.

22K gold is approximately 91.6% pure, while 18K gold is 75% pure.

For every 100 grams:

18K contains approximately 75 grams of pure gold.
22K contains approximately 91.6 grams of pure gold.
24K contains approximately 99.9 grams of pure gold.

This explains why a 22K gold product generally has a higher raw gold value than an equivalent-weight 18K product.

You can compare this with our dedicated 22K gold bars guide.

Is 18K Gold a Good Investment?

Whether 18K gold is a good investment depends on what you mean by investment.

For jewellery ownership, 18K gold can be excellent because it combines a substantial gold content with greater durability than very high-purity gold.

For pure bullion investment, however, buyers generally compare the amount of fine gold they receive against the premium they pay.

A 10g 18K item contains approximately 7.5g of pure gold. A 10g 24K item contains approximately 9.999g of fine gold.

Therefore, if two products have the same gross weight, you must compare their fine gold content, not simply the number of grams.

For investors seeking physical bullion, our guide to buying gold bars in Africa provides further information about gold bar sourcing and purchasing.

18K Gold Jewellery Price vs 18K Gold Melt Value

This distinction is extremely important.

Melt value represents the approximate value of the actual gold contained in an item.

Retail jewellery price can include much more.

For example, an 18K gold ring weighing 10 grams contains approximately 7.5 grams of pure gold. But the retail price could include the designer’s labour, manufacturing, gemstones, branding, shop overhead and taxes.

Consequently:

Retail price ≠ gold melt value

This is why someone selling an 18K gold ring to a gold buyer may receive less than the original jewellery purchase price even if the gold price has risen.

If you want to understand how gold is priced across different products, our African gold bar prices guide provides additional context.

How to Calculate the Value of 18K Gold

The simplest calculation is:

18K gold value = weight × 75% × 24K gold price per gram

Suppose you have 50 grams of 18K gold and the 24K market price is $150 per gram:

50 × 0.75 × $150 = $5,625

The theoretical gold content is therefore worth approximately $5,625.

The actual buying or selling price could be different because of the dealer’s spread, refining costs, assay fees and other transaction factors.

Example 18K Gold Value Table

18K weight	Fine gold content	Example value at $150/g 24K
1g	0.75g	$112.50
5g	3.75g	$562.50
10g	7.50g	$1,125
20g	15g	$2,250
50g	37.5g	$5,625
100g	75g	$11,250
1kg	750g	$112,500

These are illustrative calculations only, not live buying prices.

How to Check Whether Gold Is Really 18K

If you are buying or selling valuable gold, do not rely solely on the stamp.

An item marked 750, 18K, 18KT or 18ct indicates the claimed purity, but professional verification is preferable for significant transactions.

Common verification methods include:

XRF testing
Professional assay
Density testing
Acid testing
Laboratory analysis
Checking refinery or manufacturer documentation

For larger transactions, an independent assay can provide much greater confidence than visual inspection.

18K Gold Bars: Can You Buy Them?

Yes, 18K gold bars can exist, although 24K/999 or 999.9 gold is more typical for investment bullion.

An 18K gold bar contains 75% fine gold and 25% other metals.

For example, a 100g 18K bar would contain approximately 75g of pure gold.

When buying an 18K gold bar, check:

Gross weight
Fineness
Fine-gold content
Refinery or manufacturer
Serial number if applicable
Assay certificate
Seller documentation
Purchase price
Resale arrangements

18K Gold Price and Gold Market Movements

The 18K gold rate moves with the wider gold market because 18K gold contains a fixed proportion of pure gold.

When the international gold price rises, the theoretical value of 18K gold normally rises as well.

When gold falls, the underlying metal value of 18K gold also falls.

Currency movements matter too.

For example, an 18K gold price quoted in Ugandan shillings, Ghanaian cedis, Kenyan shillings, British pounds or euros can change because of both:

Gold price movement + exchange-rate movement

This is why the same amount of 18K gold can have different local-currency prices from one day to another.

Should You Buy 18K Gold in Africa?

Africa has some of the world’s most important gold-producing regions, but buying gold responsibly requires more than finding an attractive price.

You should establish:

Where the gold originated
Who owns the gold
Whether the seller is properly licensed
Whether the gold has been independently assayed
Whether the transaction is legally documented
What taxes and duties apply
How the gold will be transported
Whether the shipment is insured
What export documentation is required

What Affects the Final 18K Gold Price?

The number shown on a gold-price website is not necessarily the amount you will pay.

Your final 18K gold price can be influenced by:

Factor	Effect on price
International gold spot price	Major underlying factor
Gold purity	Determines fine-gold content
Weight	More gold means higher value
Currency exchange rate	Changes local-currency price
Dealer premium	Added to metal value
Jewellery workmanship	Can substantially increase retail price
Assay/certification	May add transaction costs
Shipping and insurance	Important for international purchases
Taxes and duties	Depend on jurisdiction
Market demand	Can affect premiums and resale

This is particularly important when comparing an 18K gold price online with an actual quotation from a gold dealer.

Frequently Asked Questions About 18K Gold Price

What is 18K gold worth today?

18K gold is 75% pure, so its theoretical metal value is approximately 75% of the current 24K gold price per gram. The actual buying price can be higher because of premiums and other costs.

How much is 18K gold per gram?

Multiply the current 24K gold price per gram by 0.75. For example, at $150/g for 24K gold, the theoretical 18K value is $112.50/g.

What does 750 mean on gold?

750 means the metal contains 750 parts pure gold per 1,000 parts, or 75% pure gold. It is the standard fineness designation for 18K gold.

Is 18K gold real gold?

Yes. Genuine 18K gold contains 75% pure gold, with the remaining 25% consisting of alloy metals.

Is 18K better than 24K?

Neither is universally better. 24K provides much higher purity and is generally preferred for high-purity bullion, while 18K offers greater hardness and is widely used for jewellery.

Is 18K gold good for investment?

It can hold significant intrinsic value, but investors should focus on fine-gold content, premiums, liquidity and resale costs. For pure bullion investment, higher-purity bars are usually easier to compare directly with the international gold price.

How much is 10 grams of 18K gold worth?

Ten grams of 18K gold contains approximately 7.5 grams of pure gold. Its theoretical value is therefore 7.5 times the current 24K gold price per gram, before premiums and other costs.

Is 18K gold common in Africa?

Yes. 18K gold is used in jewellery markets across Africa, while higher-purity gold is also widely traded as bullion. The availability and pricing vary by country and market.
