This 3.09ct lab-grown marquise sits in the three to five carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG833657400 or 833657400. Listed at 9 retailers as of October 31, 2026, with prices from HK$25,546 to HK$86,701, a HK$61,156 spread on the same certified stone. Taylor and Hart lists it at HK$86,701. 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.
