Two questions come up in almost every conversation about moissanite and money. What is it worth if I sell it, and what should I tell my insurer? The answers are not flattering, but they are simple, and knowing them in advance saves an unpleasant afternoon later.
What moissanite is worth second-hand
Very little. A loose 6.5mm colourless moissanite that cost €60 new will realistically fetch €15 to €25 on a resale marketplace, and often less, because a buyer has no reason to take a used stone over a new one with a warranty attached.
A complete ring does better, but not much. A €300 moissanite solitaire in plated silver might reach €80 to €140 on eBay or Vinted. A €900 ring in 18ct gold will hold more, though most of that value is the metal. At current scrap prices, 18ct gold is worth a meaningful fraction of the band, and a jeweller buying for scrap will pay you the metal content and treat the stone as worth nothing.
The reason is straightforward. Moissanite is manufactured, supply is effectively unlimited, and the price of new stones keeps falling as growing capacity expands. There is no scarcity to support a secondhand market, and there never will be.
What does hold value
The metal, and only the metal.
- Platinum — holds the most. Scrap value tracks the platinum price and a good bench can resell a clean band.
- 18ct gold — a solid resale floor, typically 60 to 75 per cent of the metal's spot value when sold to a trade buyer.
- 9ct gold — lower, but still real metal value in the band.
- Sterling silver with gold plating — the plating is worth nothing, and silver scrap is pennies per gram. A €300 silver moissanite ring may hold €10 of metal value.
If resale matters to you at all, put the money into the metal and the setting, not the stone. That is the opposite of diamond buying advice, and it is the correct advice here.
How insurers value a ring
Two different numbers matter and they are constantly confused.
Replacement value is what it would cost to buy the same item new from a retailer today. This is the figure you insure for. For a moissanite ring, the replacement value is the cost of a like-for-like ring, which for most pieces is €250 to €600. It is not the price of a diamond ring that looks similar.
Market value is what you could sell it for. This is what a payout on a total loss may be based on in some policies, and it is much lower. Read the settlement clause before you assume otherwise.
Most UK and EU home contents policies cover jewellery as standard only up to a single-item limit, commonly £1,000 to £2,500, or €1,500 to €3,000. Above that limit you need to list the item individually, which usually requires a valuation and sometimes a receipt or certificate.
What to declare, and how
Declare it accurately. Tell the insurer it is a moissanite ring, state the metal, the millimetre size of the centre stone, and the replacement cost. Insurers do not care that it is moissanite. They care that the sum insured matches what you actually own, because a claim for a diamond ring that turns out to be moissanite is a declined claim, and possibly a fraud file.
Keep the paperwork. A receipt showing what you paid, the certificate or report, and photographs of the ring from three angles with a ruler in frame. If you ever claim, those three things decide the outcome far more than the certificate number does.
Get a written valuation if the ring is over about €1,000 or if it uses recycled metal or a bespoke setting. A high-street jeweller will do this for €40 to €75, and most insurers want it refreshed every two to three years because metal prices move.
Insurance for a wearable ring
| Ring value | Typical route | Extra cost per year |
|---|---|---|
| Under €300 | Covered within contents single-item limit | €0 |
| €300–€1,000 | Listed item, sometimes no valuation needed | €15–€35 |
| €1,000–€3,000 | Listed item plus valuation | €30–€70 |
| Above €3,000 | Specialist jeweller policy or valuable items schedule | €70–€150 |
Two exclusions catch people out. Cover away from the home is often optional, so a ring lost on holiday may not be covered unless you added it. And accidental damage may be excluded on listed items, meaning a chipped stone from a knock is not a claim.
The blunt summary
Buy moissanite because you like how it looks and because it leaves money in the budget for something else. Do not buy it expecting it to hold value.
Insure it for what it would cost to replace, not for what a diamond would have cost. Declare it honestly. Keep the receipt.
And if you are weighing up whether the insurance is worth it on a €300 ring, run the numbers before you pay a premium. For many moissanite buyers the honest answer is that self-insuring a modest ring and putting the premium in the drawer makes more sense.
