About this 1.71ct lab-grown radiant diamond

This 1.71ct 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 LG712535601 or 712535601. Listed at 23 retailers as of October 30, 2026, with prices from $1,104 to $6,192, a $5,089 spread on the same certified stone. Brilliant Earth lists it at $6,192. 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.
