About this 0.53ct lab-grown heart diamond

This 0.53ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818658693 or 818658693. Listed at 18 retailers as of November 1, 2026, with prices from £224 to £1,051, a £828 spread on the same certified stone. Reve Diamonds lists it at £1,051. 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.
