This 1.51ct lab-grown marquise sits in the one-and-a-half to two carat band, graded E colour (colourless) and FL clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG768630028 or 768630028. Listed at 14 retailers as of October 29, 2026, with prices from HK$6,951 to HK$27,580, a HK$20,629 spread on the same certified stone. MOH London lists it at HK$27,580. 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.
