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 LG608389083 or 608389083. Listed at 2 retailers as of October 29, 2026, with prices from $573 to $661, a $88 spread on the same certified stone. MD Diamonds and Jewellers lists it at $661. 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.
