Common questions
18K Gold questions
How do I calculate what my gold is worth?⌄
Multiply the weight in grams by the purity for its karat (for example 0.583 for 14K) and by the current gold price per gram. This gives the melt value, which is the value of the pure gold content.
Does karat change how much my gold is worth?⌄
Yes. Karat measures purity, so a higher karat means more pure gold by weight and a higher melt value. 24K is 99.9% pure, while 14K is 58.3% pure.
Is melt value the same as what my jewelry is worth?⌄
Melt value is the value of the gold content alone and acts as a floor. A finished piece can be worth more once craftsmanship, brand, age, and any stones are considered. A free jewelry appraisal weighs all of these.
How accurate is a free photo-based appraisal?⌄
A photo appraisal reads the karat stamp, style, and condition to value your piece against comparable sales. It is a strong starting point and takes under 60 seconds, though a hands-on appraisal can confirm exact weight and purity.
