How Much Is My Gold Worth?
Every gold offer on earth comes from one formula: weight × purity × the day’s gold price. Here’s exactly how it works — the same math we run at our counter — so you can spot a lowball anywhere.

The formula
Step 1 — Purity. Pure gold is 24k. Your stamp tells the fraction: 10k = 41.7% gold, 14k = 58.3%, 18k = 75%, 22k = 91.7%.
Step 2 — Weight. Gold is weighed in troy ounces (31.1 grams) or pennyweight (dwt — 1 dwt = 1.555 grams). A heavy chain surprises people: weight is where the money is.
Step 3 — Spot. Multiply pure-gold weight by today’s spot price per troy ounce. That’s melt value — the floor every honest offer is built from.
What changes the offer
Broken gold pays. Scrap and broken pieces are priced on melt — and broken gold is honestly where smart sellers do best, because nobody’s charging you for "craftsmanship" on a snapped chain.
Designer and antique pieces can pay over melt — a signed Cartier or Tiffany piece is worth more than its weight, and a real buyer says so.
Stones count. Diamonds and gems in your gold add value when the buyer can grade them.

Questions we hear
- Why do offers differ so much between shops?
- Because the percentage of melt a shop pays is their choice. Shops that won’t show you the weight, the karat test, or the spot price are choosing not to. We do all three in front of you.
- Is gold-filled or gold-plated worth anything?
- Very little — the gold layer is a tiny fraction of the weight. Stamps "GF" or "HGE" give it away. We’ll test it free and tell you straight.
