This 0.68ct 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 LG799608259 or 799608259. Listed at 24 retailers as of October 31, 2026, with prices from $295 to $3,431, a $3,136 spread on the same certified stone. Do Amore Diamonds lists it at $3,431. 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.
