About this 3.16ct lab-grown radiant diamond

This 3.16ct lab-grown radiant sits in the three to five carat band, graded E 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 2486767899. Listed at 3 retailers as of October 26, 2026, with prices from $6,956 to $18,571, a $11,614 spread on the same certified stone. Brilliant Earth lists it at $18,571. 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.
