This 1.5ct lab-grown cushion sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG557236083 or 557236083. Listed at 11 retailers as of November 6, 2026, with prices from HK$2,955 to HK$18,261, a HK$15,306 spread on the same certified stone. Do Amore Diamonds lists it at HK$18,261. 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.
