Replacing a missing or damaged diamond or gemstone requires more than choosing a stone that looks approximately right. The replacement needs to suit the dimensions of the setting, stone shape and cut, while the surrounding metal must be secure enough to hold it correctly.
Diamond and gemstone replacement
We assess jewellery where a diamond, coloured gemstone or other stone has fallen out, become chipped or needs replacing. This can include rings, engagement rings, earrings, pendants and other stone-set jewellery.
A replacement may need to be matched for size, shape, colour and visual character, particularly where it sits beside existing stones. The condition of the setting is equally important: fitting a new stone into worn or damaged claws can leave the replacement at risk.
When stone replacement may be needed
- A diamond or gemstone has fallen out.
- A stone is chipped, cracked or heavily abraded.
- An existing replacement does not sit correctly.
- A setting is empty following impact or gradual wear.
- A matching stone is required beside existing diamonds or gemstones.
What happens when a diamond falls out?
We first look for the reason the stone was lost. Worn claws, a damaged setting, distortion or previous repair work may need attention before another stone is fitted. Replacing only the missing diamond without correcting the underlying problem can result in another loss.
If the surrounding claws are worn, see our claw and prong repair service.
How is a replacement stone selected?
Selection can involve the type of stone, dimensions, shape, cut and appearance. Where a replacement sits beside existing stones, matching the replacement to neighbouring stones can also be important. The correct approach depends on the jewellery and the role of the missing stone within the design.
How much does it cost to replace a stone in a ring?
Cost depends on the replacement stone and the work required to make the setting secure. Stone type, size, quality, matching requirements, claw or setting repairs and finishing can all affect the quotation.
Read our guide to stone replacement cost.
Can you assess a missing diamond from photographs?
Clear photographs of the whole item and close photographs of the empty setting are useful for an initial assessment. Some jewellery still requires physical inspection before the exact replacement and repair work can be confirmed.
Do not continue wearing an insecure setting
If another stone moves, clicks or the claws appear damaged, stop wearing the jewellery until it has been assessed. Continuing to wear a weakened setting can put additional stones at risk.
Request a stone or diamond replacement assessment
Send photographs showing the jewellery, the missing or damaged stone position and any visible damage. We can then determine the appropriate next step and whether the setting also requires repair.

Sourcing Calibrated Stones and Practical Guidance for Replacements
Many missing stones can be replaced with calibrated (mass-produced) gems that match common sizes and shapes. Calibrated stones are often a cost-effective option for repairs where an exact bespoke match is not essential, but suitability depends on the existing setting, the visual match required and the stone type.
What to expect when sourcing replacements: calibrated stones are available from multiple trade suppliers and lapidaries. We can arrange sourcing and resetting through our managed repair network, which assesses the item and recommends whether a calibrated or specially selected stone is the better solution. Factors that influence the choice include size tolerance, cut and shape, colour and visual character compared with neighbouring stones, and whether the setting needs repair before a new stone can be secured.
Matching considerations: where a replacement sits beside original stones (for example in anniversary or cluster rings) even small differences in hue, brilliance or cut can be noticeable. In those cases a hand‑matched or bespoke stone may be recommended. Calibrated stones work well where an approximate match is acceptable or where the design uses many identical stones.
Postage and handling: if you are asked to send jewellery for assessment or repair, follow agreed instructions carefully. Use a suitable tracked and insured service, package items securely and keep records of tracking. Our process typically begins with a visual and technical assessment on receipt to confirm the condition of the setting and the best replacement approach; this assessment may change the initial recommendation.
Photographs and quotations: clear photographs can support an initial assessment and help identify obvious size, shape and colour issues, but they may not be sufficient for a final quotation. A physical inspection is usually needed to confirm setting condition, measure dimensions accurately and determine whether claws, seats or other repairs are required before a stone can be fitted.
Quality and checks after refitting: a secure setting is essential. If setting repair or re-tipping is required to prevent future loss, this will be highlighted in the assessment. Following refitting, a condition check is recommended to ensure the stone is seated and the work meets the agreed specification.
