Precious Metals Reference & Buying Guide

What is a Troy Ounce vs. Standard Ounce?

Precious metals are weighed in Troy Ounces (oz t), which are heavier than standard Avoirdupois Ounces (oz) used for food. One troy ounce is exactly 31.1035 grams, whereas a standard ounce is only 28.3495 grams. Always ensure your commodity weights are converted to troy measurements.

How does Karat Fineness affect value?

Karat represents gold purity on a scale of 24. 24K gold is pure gold (99.9% fine). 18K is 18 parts gold and 6 parts alloy (75% pure), and 14K is 14 parts gold and 10 parts alloy (58.3% pure). When calculating melt value, we multiply the total weight by the purity percentage to isolate the weight of the pure gold.

What is spot price and dealer premium?

Spot price is the current global market rate at which a troy ounce of raw refined metal is trading. Dealers buy and sell bullion at a markup called the "Premium." This premium covers their refining, minting, shipping, and operational margins, usually representing a 2% to 15% charge.
