This 1.23ct lab-grown marquise sits in the classic one-carat band, graded G colour (near-colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG541281623 or 541281623. Listed at 4 retailers as of October 29, 2026, with prices from $534 to $1,407, a $873 spread on the same certified stone. MOH London lists it at $1,407. 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.
