About this 1.26ct lab-grown heart diamond

This 1.26ct lab-grown heart sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG831679977 or 831679977. Listed at 13 retailers as of October 29, 2026, with prices from £160 to £821, a £661 spread on the same certified stone. Brilliant Earth lists it at £821. 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.
