About this 1.23ct lab-grown radiant diamond

This 1.23ct lab-grown radiant sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG608300806 or 608300806. Listed at 10 retailers as of October 30, 2026, with prices from $248 to $1,756, a $1,508 spread on the same certified stone. Jared lists it at $1,756. 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.
