About this 0.54ct lab-grown heart diamond

This 0.54ct lab-grown heart sits in the half to three-quarter carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836612976 or 836612976. Listed at 16 retailers as of October 30, 2026, with prices from £191 to £1,025, a £834 spread on the same certified stone. Reve Diamonds lists it at £1,025. 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.
