Converting Jewelry Weight to Troy Ounces
Jewelers and pawn shops typically weigh items in grams using a precision scale. However, precious metals spot prices are quoted per troy ounce. To determine the melt value of a piece of jewelry, you first need to convert its gram weight to troy ounces, then multiply by the current spot price and the item's purity (karat for gold, fineness for silver).
For example, a 10-gram 14K gold chain contains 5.83 grams of pure gold (14/24 = 0.583 purity). That equals 0.18745 troy ounces of fine gold. At current spot prices, you can quickly calculate the intrinsic melt value — though dealers typically pay 70–90% of melt for scrap jewelry.
Why Grams Matter for Jewelry
The metric system is the standard in most jewelry markets worldwide. Even in the United States, where troy ounces dominate bullion trading, jewelers use grams for precision. A typical engagement ring weighs 3–6 grams, and even a small difference of 0.5 grams can affect the price when dealing with gold or platinum.
Key Conversion Factor
The exact conversion is 1 troy ounce = 31.1035 grams. To convert grams to troy ounces, divide the gram weight by 31.1035. This factor is universally used across all precious metals markets and is essential for anyone buying, selling, or appraising gold, silver, platinum, or palladium.
