About this 1.22ct lab-grown heart diamond

This 1.22ct lab-grown heart sits in the classic one-carat band, graded D colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG846641831 or 846641831. Listed at 17 retailers as of October 23, 2026, with prices from £150 to £1,046, a £896 spread on the same certified stone. Brilliant Earth lists it at £1,046. 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.
