The result calculator displays the melt value, which is the pure gold content of your piece at the current spot rate. This is not the same value that buyers pay you. All buyers have different payout rates, and we will guide you as follows.
What Is 18K Gold?
18K gold contains 18 parts pure gold out of 24. It contains 75% pure gold, with the remaining 25% made up of metal alloys such as silver, copper, or zinc. It is known for its deeper yellow color, premium feel, and lasting beauty.
The perfect balance of metal alloys makes it harder, durable for daily wear, and resistant to tarnishing over time. It is widely used in engagement rings, wedding bands, family heirlooms, and other jewelry pieces.
What the 750 Hallmark Means
The three-digit number “750” stamped on a jewelry piece means it is an 18K gold piece. It is the official European and internationally recognized stamp for 18K gold. This hallmark is usually stamped on many jewelry pieces, like inside the band of rings, on the clasp of necklaces and chains, and behind earrings.
Gold Stamp | Gold Purity Meaning |
|---|---|
18K | 75% pure gold |
18KT | Same purity as 18K |
750 | 75% gold content |
AU750 | Gold with 75% purity |
.750 | Decimal purity mark |
How to Identify 18K Gold on Jewelry at Home
First, you look at the stamp of your jewelry pieces. The stamp is typically on the inner band of a ring, the clasp of a necklace or bracelet, or the post of an earring. Beyond the stamp, you can do a magnetic test to verify your pieces. It’s a quick test to verify that gold, which is nonmagnetic, is present. To identify real value, you can conduct a professional acid test or an XRF (X-ray fluorescence) analysis.
18K Yellow Gold vs White Gold vs Rose Gold
All three colors of 18K gold carry the same melt value per gram. Here are the alloy combinations of each gold:
How to Calculate 18K Gold Price Per Gram
You can calculate the price of 18K gold per gram at home. Here’s the guide:
Formula:
(Spot Price Per Gram) x 0.75 x Weight in Grams = Melt Value
The 24K gold spot price per gram is the starting point. To convert that to the 18K price per gram, multiply by 0.75. Then multiply by your piece’s weight in grams.
Worked Example:
That $876 is the raw gold content value at spot price.
How to Weigh Your 18K Gold Accurately at Home
To estimate the exact value of your gold, always weigh it in grams, because the 18k gold per gram rate is what determines your item’s true melt value. Gold spot prices are quoted globally in troy ounces, not standard ounces. One troy ounce equals 31.1 grams, and any incorrect conversion will create an underestimate or overestimate of the gold’s value.
Here are tips you should follow when weighing your jewelry pieces:
Factors Influencing 18k Gold Price Per Gram
Here are all the factors that affect the value of 18K gold price per gram:
Global Gold Spot Price
The global gold spot price is the main factor affecting its value. When it rises or falls, gold prices also change.
Weight & Purity
Weight and purity are also the main factors in evaluating jewelry value. Since 18K gold has a higher gold content and weighs more than lower karats, it is more valuable.
US Dollar Strength
Gold trades globally in the US dollars. So, when the dollar weakens, the price of 18 karat gold rises.
Federal Reserve Policy, Interest Rates, and Inflation
Federal Reserve decisions on interest rates and inflation can strongly influence 18K gold prices. Gold prices often rise during high inflation or economic uncertainty.
Geopolitical Events
Global conflicts, political instability, and economic uncertainty can increase gold demand. During this time, many investors buy gold as a safe-haven asset to protect their wealth.
Central Bank Gold Buying
The central bank plays a major role in the global gold market, as they hold gold as its largest reserve asset. They buy gold in large quantities when demand increases, thereby raising prices.
Market Supply and Demand
Depending on the market supply and customers’ demand, prices also change. Higher jewelry demand and investment in gold push prices upward.
Jewelry Demand
Designer brands, luxury collections, and popular jewelry styles can increase the value of 18K gold pieces.
Why Your 18K Gold Is Worth Less Than Market Price
The 18K gold price per gram you see in the calculator result above for your item is the raw market value of pure gold. It is not the one that buyers pay you. Buyers normally deduct refining costs, testing fees, dealer margins, and resale risks before making an offer.
Pawn Shops vs Online Gold Buyers vs Refineries: Payout Comparison
Buyer Type | Typical Payout Rate |
|---|---|
Pawn Shop | 40% – 60% of melt value |
Cash-for-Gold Store | 60% – 75% of melt value |
Online Gold Buyer | 80% – 92% of melt value |
Gold Refinery (Bulk Sales) | 85% – 95% of melt value |
Why Jewelry Costs More Than Melt Value?
When you buy 18K gold jewelry from a store, you pay more than its melt value. It is because the jewelry covers labor, design, retail markup, and brand value. But when you sell your jewelry as scrap, buyers will pay you for its gold content rather than its craftsmanship or original retail price.
18K Gold Price Per Gram vs Other Karats
Here’s the detailed comparison that shows how the price of 18k gold per gram stacks up against all other karats:
Karat | Purity | Fineness Stamp |
|---|---|---|
10K | 41.7% | 417 |
14K | 58.3% | 585 |
18K | 75.0% | 750 |
22K | 91.7% | 916 |
24K | 99.9% | 999 |
How to Sell 18K Gold at the Best Price
Selling 18K gold items demands three principles: know your item’s melt value, get multiple quotes, and choose your buyer based on payout rate.
Where to Sell 18K Gold
Here are all the selling options from which you can sell your item and choose an accurate buyer:
How to Get Multiple Quotes and Negotiate
For the best payout, get at least three quotes before making a final deal. Gold prices fluctuate throughout the day, so get quotes on the same day for better rate comparison. Ask each buyer about the weight they measure for your item, the karat they assigned, the payout percentage, and how they arrived at their 18k price per gram offer. A legitimate buyer will provide you with all details without hesitation. If the buyer refuses to provide this information, then walk away.
Red Flags When Selling
Here are the red flags you need to avoid when you see buyers doing these things:
Is 18K Gold a Good Investment
18K gold is a good investment due to its mix of durability, gold content, and lasting market demand.

A common misconception about 18K gold is that it is 100% pure gold, when in reality it contains 75% pure gold and 25% alloy metals. Many buyers also wonder how much 18k gold is worth and assume all 18K jewelry has the same value, but factors like craftsmanship, weight, market prices, and dealer margins can affect the final price.
