This 1.25ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG836603482 or 836603482. Listed at 24 retailers as of November 4, 2026, with prices from $446 to $2,684, a $2,238 spread on the same certified stone. Brilliant Earth lists it at $2,684. 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.
