About this 1.88ct lab-grown radiant diamond

This 1.88ct lab-grown radiant sits in the one-and-a-half to two carat band, graded D colour (colourless) and FL clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG818653767 or 818653767. Listed at 22 retailers as of October 30, 2026, with prices from $1,157 to $8,100, a $6,943 spread on the same certified stone. Rare Carat lists it at $8,100. 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.
