The Diamond Resale Problem

Imagine purchasing a diamond at full retail price, reflecting the manufacturer's cutting cost, the trader's margin, the retailer's markup and certification costs, all covered throughout this page as genuine value-adding steps in the journey from rough stone to finished jewellery, and then discovering, if you ever try to resell that same diamond, that the resale market values it considerably below what you originally paid, a genuine, structural feature of diamond ownership that catches many first-time buyers by surprise.

This resale gap exists because the retail price embeds all of those supply chain value-addition costs, covered elsewhere on this site, cutting, certification, wholesale and retail margins, that a resale buyer isn't willing to pay for a second time, a secondhand diamond essentially competes on the stone's raw wholesale value alone, closer to something resembling the Rapaport benchmark covered elsewhere on this site, rather than commanding the full retail price a first-time buyer originally paid including all the intermediary value addition.

This resale challenge has become genuinely more pronounced specifically for lab-grown diamonds, covered under the price collapse discussion elsewhere on this site, a lab-grown diamond purchased even a few years ago at a considerably higher price point than today's dramatically lower wholesale cost, covered elsewhere on this site, can find its resale value has fallen even more steeply than a comparable natural diamond's would, since the underlying wholesale lab-grown diamond price itself has kept declining as production scaled, compounding the standard retail-to-resale value gap with genuine ongoing commodity price deflation.

This dynamic matters directly for how consumers, jewellers and financial advisors, covered elsewhere on this site as relevant to LKR Advisors' own wealth advisory context, should think about diamonds as a purchase category, unlike gold, covered elsewhere on this site, which maintains meaningful resale liquidity tied closely to prevailing commodity prices, diamonds, and lab-grown diamonds specifically, function considerably more like a consumption purchase for personal enjoyment than a value-preserving asset, a genuinely important distinction worth understanding clearly before treating diamond jewellery as any kind of investment vehicle.
