Lab-grown or natural? The same stone, both ways
Identical shape, weight and grade. One is grown in a reactor in weeks, the other in the mantle over a billion years — and they are chemically the same. The difference is entirely in what they cost and what they are worth later.
The stone
Very Good cut; natural graded GIA, lab-grown IGI.
What the numbers mean
Retail is what you would pay today. Resale is what a buyer would offer the day after — for lab-grown stones that is already close to nothing, because a stone that can be manufactured to order has no scarcity for a secondary market to price. Natural resale is weak too, but it is a market.
The honest way to decide: if you want the largest, cleanest stone you can wear for the money and do not care what it is worth later, lab-grown wins and it is not close. If the stone is also meant to be an heirloom, a store of value, or something you might one day need to sell, that is what the natural premium buys — nothing else.
Five years on
Lab-grown wholesale prices fell by roughly 85% between 2022 and 2025 and have not stopped falling. We model resale at 5–12% of today's retail, and expect today's retail itself to be lower in five years. A natural stone's resale band has been stable for decades. The chart above prices both today; the direction of travel is the part to weigh.
