About this 1.04ct lab-grown heart diamond

This 1.04ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG844657590 or 844657590. Listed at 15 retailers as of October 27, 2026, with prices from £131 to £819, a £688 spread on the same certified stone. Brilliant Earth lists it at £819. 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.
