About this 1.65ct lab-grown radiant diamond

This 1.65ct lab-grown radiant sits in the one-and-a-half to two 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 5486187217. Listed at 24 retailers as of October 30, 2026, with prices from $1,775 to $8,058, a $6,283 spread on the same certified stone. Taylor and Hart lists it at $8,058. 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.
