What Influences the Price of Gold Jewellery?
Top Gold Team · 4 September 2025
Two rings can look almost identical and be worth completely different amounts. People are often surprised by this the first time they bring jewellery in for a valuation, so it’s worth breaking down what actually drives the number.
Purity comes first
Gold jewellery is rarely 100% gold. It’s mixed with other metals for strength and durability, and the ratio is stamped as a karat: 9K, 14K, 18K, 22K, or 24K. 24K is as close to pure as jewellery gets. 9K is only 37.5% gold by weight, with the rest made up of alloy metals.
This matters because two rings of the same size and design can differ hugely in value if one is 9K and the other is 18K. We test purity with XRF technology rather than relying on the stamp alone, since stamps can wear off, be mismatched after a repair, or occasionally be inaccurate.
Weight, obviously, but precisely
The heavier the piece, the more gold it contains, assuming purity stays constant. We weigh on calibrated scales down to a fraction of a gram, because at gold’s current price even small differences add up.
The live market rate
Gold trades on a global market and the price moves throughout the day. A payout that was fair yesterday can be a few dollars off today. This is why we calculate against the live spot rate at the time you’re in store, not a number pulled from last week.
What doesn’t carry over: workmanship
Here’s the part that trips people up. A beautifully crafted ring with intricate detailing costs more to make than a plain band of the same weight and purity, but that extra labour cost doesn’t come back to you in a buy-back price. We’re paying for the metal, not the craftsmanship. If a piece has genuine designer or antique value beyond its gold content, that’s a different conversation, and one worth having before you decide to sell for scrap.
Putting it together
Purity times weight times the current gold price gives you the raw metal value. From there, a buyer applies their margin, which covers testing, overheads, and the fact that the gold usually needs to be refined before it re-enters the market. A transparent buyer will walk you through each of those steps rather than just handing you a final figure.
