This 1.5ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG529262305 or 529262305. Listed at 13 retailers as of October 29, 2026, with prices from HK$2,181 to HK$9,725, a HK$7,544 spread on the same certified stone. MOH London lists it at HK$9,725. 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.
