About this 0.81ct lab-grown heart diamond

This 0.81ct lab-grown heart sits in the just-under-one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG797643306 or 797643306. Listed at 15 retailers as of October 29, 2026, with prices from £167 to £894, a £727 spread on the same certified stone. Reve Diamonds lists it at £894. 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.
