About this 1.73ct lab-grown radiant diamond

This 1.73ct 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 6491874605. Listed at 7 retailers as of October 31, 2026, with prices from $2,414 to $8,178, a $5,764 spread on the same certified stone. Frank Darling lists it at $8,178. 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.
