Fancy-shape lab-grown stones are stabilising, closing a gap that opened last year when rounds settled first.
- Lab-grown rounds found a floor earlier this year; fancy shapes kept sliding for several months afterward.
- Over the summer, month-on-month declines in lab-grown ovals, cushions and emerald cuts narrowed sharply, following the pattern rounds set earlier.
- Emerald and radiant cuts, which use more rough per carat of finished stone, have firmed the most among fancies.
For buyers who prefer a fancy shape but held off waiting for lab-grown prices to bottom, the gap to rounds is closing rather than widening further. Make still separates well-cut fancies from the rest — the cut guide and individual shape pages cover proportions to check before price. Browse lab-grown fancy shapes.
