About this 1.5ct lab-grown heart diamond

This 1.5ct lab-grown heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG837641669 or 837641669. Listed at 17 retailers as of November 4, 2026, with prices from £177 to £1,037, a £860 spread on the same certified stone. Brilliant Earth lists it at £1,037. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
