Spot price
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.
Free UK precious-metal value tool
Estimate the indicative intrinsic value of gold or silver in GBP from weight and purity. This calculator is for precious metals; it does not calculate industrial base metals such as copper, brass, aluminium or steel.
The figure is an indicative intrinsic metal value, not a guaranteed purchase offer. Branded, signed, gemstone-set, antique or collectable pieces may be worth more than their metal content.

Waiting for current market data.
Estimate only, not a purchase offer or guaranteed price. Spot and FX prices can move, third-party data may be delayed, and any Imperial Time offer is confirmed only after specialist review, testing and inspection.

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
Hallmarks help identify metal fineness. Gold is commonly described by carat and millesimal fineness; silver by fineness marks such as 925, 958 and 999.
375 = 9ct / 37.5%
585 = 14ct / 58.5%
750 = 18ct / 75.0%
916 = 22ct / 91.6%
999 = 24ct / 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
Example formula for 10g of 9ct gold: 10g × 0.375 × current fine-gold £/g.
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.

Bring the item to our Kensington showroom or start with an enquiry. A specialist can assess purity, condition, stones, brand and resale value before you decide how to sell.
Questions answered
This Imperial Time calculator covers gold and silver precious metals. It is not an industrial base-metal calculator and does not price copper, brass, aluminium, steel or similar materials.
It multiplies weight by purity and by the current fine-metal value per gram. This produces an indicative intrinsic-value reference, not a guaranteed purchase price.
A lower-purity alloy contains less fine precious metal at the same total weight. For example, 9ct gold is 37.5% fine gold while 18ct gold is 75%.
The page requests current spot-market references and a GBP conversion rate. If a live request temporarily fails, a recent session-cached reference may be shown and is clearly labelled.
No. The result is an indicative intrinsic metal value. Any purchase offer is confirmed only after specialist review, testing and inspection.
Yes. Brand, maker, gemstones, rarity, design, condition, provenance and collectability can make a complete item worth substantially more than its melt value.
