Understand the number
The spot price is a market reference for fine precious metal. It changes through the trading day and is normally quoted for pure metal rather than finished jewellery.
The calculator adjusts the fine-metal reference for the item’s stated purity and weight. This estimates the value of the precious-metal content itself.
An actual offer can differ after testing, inspection, refining considerations and market movements. Resale, brand or collectable value may also make a piece worth more than melt value.
Purity guide
Silver fineness marks show how much of the alloy is fine silver. Sterling Silver 925 is 92.5%, Britannia 958 is 95.8%, and fine 999 is 99.9%.
500 = 50.0%
800 = 80.0%
900 = 90.0%
925 = Sterling / 92.5%
958 = Britannia / 95.8%
999 = Fine / 99.9%
A hallmark is useful evidence of stated fineness, but Imperial Time may still test or inspect an item before making an offer.
Transparent calculation

The current fine-metal value per gram is derived from the latest available spot-market reference converted to GBP. The same rate object powers the calculator, table and examples.

Do not scrap value you cannot replace
Raw metal value is only one component of value. Signed or branded jewellery, luxury watches, diamond or gemstone-set pieces, antique and period jewellery, unusual craftsmanship, coins and collectable objects can command a premium above their intrinsic metal content.
Before selling solely for metal value, consider whether the maker, brand, stones, rarity, design, condition, provenance or resale demand could make the piece worth more. Imperial Time can assess the complete item rather than assuming it should be melted.
