| Item weight | Pure gold content | Estimated melt value |
|---|---|---|
| 1 g | 0.585 g | $78.91 |
| 5 g | 2.925 g | $394.56 |
| 10 g | 5.850 g | $789.12 |
| 20 g | 11.700 g | $1,578.23 |
A worked 14K calculation
For a 10 g item with no non-gold deductions, multiply 10 by 0.585 to obtain 5.85 g of pure gold. Divide the reference of $4,195.60 USD per troy ounce by 31.1034768, then multiply by 5.85. The estimated metal value is $789.12 USD.
If stones and other non-gold parts weigh 2 g, calculate the gold content on the remaining 8 g, not the full 10 g. A hallmark is a starting assumption; an assay may find a different purity.
Metal value, buyer offer and retail price
Metal value estimates the gold content. A buyer's net cash offer is what you receive after any fees and deductions. Retail jewelry prices may include labor, brand premiums, stones and taxes. These figures answer different questions.
The 70% and 90% figures in the calculator are hypothetical arithmetic examples, not typical payouts or a fair-price range. Compare itemized net quotes using the same tested weight and purity. Compare multiple buyer quotes or read the calculation method.
What is 14K gold?
14-karat gold contains approximately 58.5% pure gold, with the remainder made from metals that influence color and durability. It is widely used for rings, chains, bracelets and other everyday jewelry in the United States.
14K and 585 hallmarks
Common marks include “14K,” “14KT” and “585.” The 585 mark means roughly 585 parts of gold per thousand. Older or repaired pieces may test differently from the stamped mark.
How the per-gram estimate works
For a multi-item lot, weigh pieces together only when they share the same tested purity. Calculate different karats separately and add the results.
Comparing a 14K buyer offer
Use the offer calculator to divide a buyer's final cash quote by estimated melt value. This creates a consistent percentage for comparing a pawn shop, local gold buyer and mail-in service.
