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 VS2 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG785606163 or 785606163. Listed at 12 retailers as of November 2, 2026, with prices from $236 to $2,185, a $1,949 spread on the same certified stone. MOH London lists it at $2,185. 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.
