About this 0.54ct lab-grown heart diamond

This 0.54ct 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 LG825658640 or 825658640. Listed at 17 retailers as of November 1, 2026, with prices from £227 to £1,062, a £835 spread on the same certified stone. Reve Diamonds lists it at £1,062. 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.
