This 1.23ct lab-grown marquise sits in the classic one-carat band, graded D colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG753506828 or 753506828. Listed at 12 retailers as of November 3, 2026, with prices from $745 to $3,724, a $2,979 spread on the same certified stone. MOH London lists it at $3,724. 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.
