About this 12.1ct lab-grown radiant diamond

This 12.1ct lab-grown radiant sits in the over five carat band, graded H colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade and certified by IGI LG589390525 or 589390525. Listed at 14 retailers as of October 31, 2026, with prices from $3,125 to $20,073, a $16,948 spread on the same certified stone. Brilliant Earth lists it at $20,073. 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.
