Is a diamond an investment? An honest answer

What a diamond is worth after you buy it, why resale is lower than you expect, and how our exchange works.

Customers sometimes tell us they are buying a diamond partly as an investment, the way families buy gold. We think it is fairer to explain how diamond value really behaves before you spend.

Gold has a single daily price that every jeweller in India follows, so selling it is simple. Diamonds do not. Each stone is priced on its own weight, colour, clarity and cut, and a buyer will offer you the wholesale price, not the retail price you paid. For a natural stone, that usually means getting back 50 to 70 per cent of the purchase price, depending on size and grade, and less for small stones under 0.30 ct.

Lab-grown diamonds are different again. Their prices have fallen steadily as production has grown, so a lab-grown stone bought today will almost certainly be worth less in five years. That does not make it a poor choice for a ring you love; it simply means it is not a store of value.

What we can offer is an exchange. Any Tapti diamond can be brought back at any time and its current value counted against a new piece, so you pay only the difference. Bhavesh from Vadodara did this with his wife’s pendant after ten years. It is a fair way to upgrade, but it is not the same as selling for cash. Our view: buy a diamond because you want to wear it. If your aim is to save for the future, gold coins or a bank deposit will serve you better.
