This 1.5ct lab-grown cushion sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG499105432 or 499105432. Listed at 12 retailers as of November 1, 2026, with prices from HK$2,633 to HK$11,675, a HK$9,042 spread on the same certified stone. MOH London lists it at HK$11,675. 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.
