About this 2.78ct lab-grown radiant diamond

This 2.78ct lab-grown radiant sits in the two to three 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 7506164040. Listed at 19 retailers as of October 27, 2026, with prices from $3,483 to $26,245, a $22,762 spread on the same certified stone. Zales lists it at $26,245. 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.
