This 1.21ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI LG494177484 or 494177484. Listed at 8 retailers as of November 1, 2026, with prices from $598 to $1,616, a $1,018 spread on the same certified stone. MOH London lists it at $1,616. 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.
