This 0.5ct lab-grown marquise sits in the half to three-quarter carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG807614156 or 807614156. Listed at 13 retailers as of October 31, 2026, with prices from $370 to $2,662, a $2,292 spread on the same certified stone. Do Amore Diamonds lists it at $2,662. 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.
