Cut quality on small lab-grown fancy shapes has improved faster than any other size or shape category over the past year, closing a gap that used to favour rounds heavily.

  • Cutters have had more small fancy-shape rough to practise on as lab-grown volumes have grown, which has driven faster proportion and symmetry improvements at this size specifically.
  • This builds on the broader trend of fancy-shape lab-grown catching up to rounds on price stability, extending it specifically to cut quality at smaller sizes.
  • Buyers who avoided small fancy-shape lab-grown stones a year or two ago over cut-quality concerns should take another look at current stock.

Cut quality varies most at this size, so it's worth comparing actual stones rather than assuming all lab-grown fancy melee is equivalent. Browse fancy shapes or contact us for a recommendation.
