This 0.81ct lab-grown heart sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836619139 or 836619139. Listed at 19 retailers as of November 4, 2026, with prices from £223 to £1,106, a £883 spread on the same certified stone. MOH London lists it at £1,106. 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.
