This 1.5ct lab-grown marquise sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG843629193 or 843629193. Listed at 4 retailers as of October 27, 2026, with prices from HK$3,716 to HK$7,310, a HK$3,595 spread on the same certified stone. Taylor and Hart lists it at HK$7,310. 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.
