About this 0.9ct lab-grown marquise diamond

This 0.9ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG735503436 or 735503436. Listed at 22 retailers as of October 25, 2026, with prices from $298 to $2,301, a $2,003 spread on the same certified stone. Brilliant Earth lists it at $2,301. 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.
