About this 0.51ct lab-grown cushion diamond

This 0.51ct 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 LG797674482 or 797674482. Listed at 17 retailers as of October 29, 2026, with prices from £92 to £863, a £772 spread on the same certified stone. MOH London lists it at £863. 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.
