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 gold value tool
Estimate the indicative intrinsic value of 9ct, 14ct, 18ct, 22ct or 24ct gold in GBP using current gold spot pricing and the latest available GBP conversion rate.
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.

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
UK gold hallmarks commonly identify fineness in parts per thousand. For example, 375 indicates 37.5% fine gold, corresponding to 9 carat gold.
375 = 9ct / 37.5%
585 = 14ct / 58.5%
750 = 18ct / 75.0%
916 = 22ct / 91.6%
999 = 24ct / 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.

Questions answered
The indicative intrinsic value of 9ct gold is 37.5% of the current fine-gold value per gram. The live table applies that purity factor automatically. An actual purchase offer can differ after inspection and testing.
Multiply the item’s weight in grams by its gold purity and by the current fine-gold value per gram. For example, 9ct gold uses a purity factor of 0.375.
A 375 fineness mark indicates 375 parts of fine gold per 1,000 parts of alloy, equivalent to 37.5% gold or 9 carat gold.
At the same weight, 18ct gold contains twice the fine-gold proportion of 9ct gold: 75% versus 37.5%. Finished jewellery value can also depend on brand, stones, condition and collectability.
No. It shows an indicative intrinsic metal value from current reference pricing. Any Imperial Time offer is confirmed after specialist assessment, testing and inspection.
Yes. Brand, maker, gemstones, age, design, condition, rarity, provenance and resale demand can make a complete piece more valuable than its raw gold content.
