This 0.51ct lab-grown cushion sits in the half to three-quarter carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG841646070 or 841646070. Listed at 5 retailers as of October 29, 2026, with prices from $348 to $1,320, a $972 spread on the same certified stone. MOH London lists it at $1,320. 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.
