About this 4.51ct lab-grown radiant diamond

This 4.51ct lab-grown radiant sits in the three to 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 1533678398. Listed at 19 retailers as of October 28, 2026, with prices from $11,745 to $50,693, a $38,948 spread on the same certified stone. Frank Darling lists it at $50,693. 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.
