About this 1.02ct lab-grown heart diamond

This 1.02ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG842604007 or 842604007. Listed at 19 retailers as of October 30, 2026, with prices from £149 to £1,008, a £859 spread on the same certified stone. Brilliant Earth lists it at £1,008. 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.
