This 0.71ct lab-grown heart sits in the half to three-quarter carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG840620858 or 840620858. Listed at 17 retailers as of November 1, 2026, with prices from £136 to £849, a £712 spread on the same certified stone. Reve Diamonds lists it at £849. 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.
