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 very-good cut grade and certified by IGI LG826685966 or 826685966. Listed at 11 retailers as of November 2, 2026, with prices from $202 to $2,070, a $1,868 spread on the same certified stone. MOH London lists it at $2,070. 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.
