Gold jewelry is usually not made of pure gold, as this metal is too soft and any items made of it would bend easily. Instead, it is mixed with other metals, such as zinc and copper, and the resulting alloy is harder and more suitable for making jewelry. Karat is the most widely used...
The amount and percentages of other alloys can do interesting things to gold. Pure gold (which is24kt, is measured in troy standards from 1-24. One troy ounce equals 31.1033 grams), isbright yellow-orange in color(thinkgold bullions). It’s almost like the color of abeautiful golden sun...

The purity of gold alloys is expressed in karats, which is the mass fraction of gold multiplied by 24. Pure gold is 24 kt, whereas 16 kt gold jewelry typically contains 66.666667% gold, 16.666667% silver, and 16.666667% copper (by mass). Estimate ...
However, because platinum jewelry is more pure (typically 95 percent platinum versus 58.5 percent gold in 14 kt. gold jewelry) and more dense than gold, it will still cost a bit more than a similar gold ring," she notes. (On July 9, 2019, the price of platinum was $816.60 per ounce...
If it's 14 kt, you can weigh it, multiply by 14/24 and by the current price of gold to determine it's intrinsic value. If it's only electroplated with gold, it has zero intrinsic metal value and is only worth it's decorative value as costume jewelry. Regards, Ted Mooney, P.E....
