About this 0.71ct lab-grown cushion diamond

This 0.71ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG799665833 or 799665833. Listed at 17 retailers as of October 30, 2026, with prices from £120 to £760, a £639 spread on the same certified stone. Reve Diamonds lists it at £760. 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.
