About this 0.74ct lab-grown heart diamond

This 0.74ct 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 LG840632593 or 840632593. Listed at 15 retailers as of November 4, 2026, with prices from £179 to £977, a £798 spread on the same certified stone. Reve Diamonds lists it at £977. 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.
