About this 1.72ct lab-grown radiant diamond

This 1.72ct 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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 3515126475. Listed at 24 retailers as of October 30, 2026, with prices from $2,305 to $10,456, a $8,151 spread on the same certified stone. Taylor and Hart lists it at $10,456. 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.
