This 1.23ct lab-grown marquise sits in the classic one-carat band, graded D colour (colourless) and VS2 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG694530230 or 694530230. Listed at 14 retailers as of October 29, 2026, with prices from $401 to $1,965, a $1,564 spread on the same certified stone. MOH London lists it at $1,965. 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.
