About this 1ct lab-grown radiant diamond

This 1ct lab-grown radiant sits in the classic one-carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included) and certified by IGI LG621498640 or 621498640. Listed at 2 retailers as of November 5, 2026, with prices from $697 to $809, a $111 spread on the same certified stone. MD Diamonds and Jewellers lists it at $809. 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.
