About this 5.15ct lab-grown radiant diamond

This 5.15ct lab-grown radiant sits in the over five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7518886008. Listed at 15 retailers as of October 28, 2026, with prices from $25,582 to $62,764, a $37,182 spread on the same certified stone. Yorxs lists it at $62,764. 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.
