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 IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG841643642 or 841643642. Listed at 22 retailers as of October 30, 2026, with prices from £183 to £1,000, a £817 spread on the same certified stone. Brilliant Earth lists it at £1,000. 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.
