About this 0.55ct lab-grown cushion diamond

This 0.55ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade and certified by IGI LG817672704 or 817672704. Listed at 14 retailers as of October 30, 2026, with prices from £133 to £794, a £661 spread on the same certified stone. Reve Diamonds lists it at £794. 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.
