About this 1.64ct lab-grown radiant diamond

This 1.64ct lab-grown radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG529247638 or 529247638. Listed at 6 retailers as of October 31, 2026, with prices from $356 to $1,689, a $1,333 spread on the same certified stone. Michael Trio lists it at $1,689. 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.
