This 1.81ct lab-grown marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG835668048 or 835668048. Listed at 13 retailers as of November 1, 2026, with prices from HK$13,257 to HK$41,529, a HK$28,273 spread on the same certified stone. With Clarity lists it at HK$41,529. 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.
