About this 1.86ct lab-grown radiant diamond

This 1.86ct 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 LG833668463 or 833668463. Listed at 9 retailers as of October 30, 2026, with prices from $1,429 to $6,195, a $4,766 spread on the same certified stone. Blue Nile lists it at $6,195. 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.
