About this 1.7ct lab-grown radiant diamond

This 1.7ct 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 and certified by IGI LG729529458 or 729529458. Listed at 11 retailers as of October 28, 2026, with prices from $1,164 to $6,046, a $4,882 spread on the same certified stone. Brilliant Earth lists it at $6,046. 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.
