How much does it cost to replace a diamond that fell out of a ring?
Quick answer
In Australia, replacing a small accent diamond usually costs $100 to $300 with setting. A centre stone costs whatever the new diamond costs, plus about $200 to $300 to re-tip four worn claws in gold or platinum. A 1 carat lab-grown replacement runs about $1,000 to $1,600, while a comparable mined diamond starts near $3,900. Whatever let the first stone go has to be repaired before a new one goes in, or you risk losing that one too.
What each part of the repair costs
The bill has two parts: the diamond, and the work to make the setting safe again. On a small pavé or accent stone, the labour often costs more than the diamond. On a centre stone, the diamond is nearly all of it.
The prices below come from published 2025 and 2026 Australian jeweller price lists and our own stone feed in September 2026. Expect the top of each range for platinum, white gold that needs re-plating, or an unusual setting.
| Repair | Typical Australian price |
|---|---|
| Setting a small stone under 2.5mm (labour only) | $35 to $50 per stone |
| Replacing a small accent diamond, stone and setting | $100 to $300 |
| Re-tipping one claw in gold or platinum | $60 to $100 |
| Re-tipping four claws in gold or platinum | $200 to $300 |
| Rebuilding four claws completely | $240 to $385 |
| Rhodium re-plating on white gold | $80 to $200 |
| 1 carat lab-grown centre diamond | $1,000 to $1,600 |
| 1 carat mined centre diamond (H colour, VS2) | From about $3,900 |
Why the diamond fell out, and why it changes the quote
Diamonds rarely fall out without warning. The usual cause is a claw that has worn thin, been bent by a knock or been caught on fabric and lifted. Less often, a solder join fails or a small stone chips and works loose.
Whatever let the first stone go will let the next one go, so a good jeweller repairs the setting before setting a new diamond and checks every other stone while the ring is on the bench. If one pavé stone has fallen out, the stones beside it are often loose too, which is why a quote can cover more than the missing diamond.
Will insurance or a warranty cover it?
Jewellery insurance usually covers a lost diamond, including the cost of setting the replacement, as long as the ring is listed on the policy with a current valuation. Contact your insurer before you pay for the repair, since some insurers want to approve the quote or choose the jeweller.
A warranty usually does not cover it. Most jewellers, including us, cover a stone lost because the setting was made badly, but not one lost to worn claws, knocks or everyday wear.

Ask the studioFrequently asked questions
- What should I do if a diamond falls out of my ring?
- Take the ring off and put it somewhere safe. Search where you have been, including pockets, bags, bedding and clothing, because a stone often catches in fabric. If you find the diamond, keep it in a closed box rather than a loose pouch. Then contact your insurer before you book the repair.
- Can I glue the diamond back in?
- No. Glue will not hold a diamond through daily knocks, it dulls the stone from behind, and the jeweller has to clean it all out before doing the proper repair.
- How long does it take to replace a lost diamond?
- A small accent stone usually takes about one to two weeks. A centre stone takes longer if a matching diamond has to be sourced or the claws need rebuilding.
- How can I stop it happening again?
- Have the ring checked by a jeweller once a year and re-tip claws as soon as they look thin. Between checks, look for gaps between the claws and the stone, and listen for a faint rattle when you tap the ring near your ear. Take it off for the gym, gardening and heavy cleaning.
