About this 0.68ct lab-grown heart diamond

This 0.68ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG756513800 or 756513800. Listed at 9 retailers as of October 30, 2026, with prices from £278 to £1,978, a £1,699 spread on the same certified stone. Do Amore Diamonds lists it at £1,978. 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.
