About this 1.21ct lab-grown marquise diamond

This 1.21ct lab-grown marquise sits in the classic one-carat band, graded F colour (colourless) and VVS2 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG825623092 or 825623092. Listed at 17 retailers as of November 1, 2026, with prices from $300 to $1,260, a $960 spread on the same certified stone. Brilliant Earth lists it at $1,260. 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.
