This 0.81ct lab-grown marquise sits in the just-under-one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG816662571 or 816662571. Listed at 23 retailers as of November 2, 2026, with prices from HK$1,538 to HK$15,153, a HK$13,615 spread on the same certified stone. Diamond Exchange Canada lists it at HK$15,153. 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.
