LAB-GROWN DIAMONDS continue to make inroads into independent jewelry stores, with more than half of jewelers, or 52%, now stocking the once-controversial merchandise, according to the 2020 INSTORE Big Survey. That is up from 10 percent just four years ago.
According to the jewelers who stock man-made diamonds, their average ticket size is typically lower than for natural diamonds – 30% of them said it was “smaller” and 28% said it was “much “smaller” – but the margins are better. Altogether, 70% of those selling lab-grown diamonds said they get a better return than from natural diamonds, with more than one in four saying their profit is 25% higher.
