About this 1.01ct lab-grown heart diamond

This 1.01ct lab-grown heart sits in the classic one-carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG825667185 or 825667185. Listed at 19 retailers as of October 28, 2026, with prices from £255 to £1,599, a £1,345 spread on the same certified stone. Brilliant Earth lists it at £1,599. 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.
