About this 0.7ct lab-grown heart diamond

This 0.7ct 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 LG840620864 or 840620864. Listed at 17 retailers as of October 30, 2026, with prices from £170 to £957, a £787 spread on the same certified stone. Reve Diamonds lists it at £957. 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.
