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 LG840664981 or 840664981. Listed at 12 retailers as of October 26, 2026, with prices from $119 to $1,105, a $986 spread on the same certified stone. MOH London lists it at $1,105. 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.
