This 1.76ct lab-grown cushion sits in the one-and-a-half to two carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG779634282 or 779634282. Listed at 16 retailers as of October 31, 2026, with prices from HK$4,731 to HK$30,677, a HK$25,946 spread on the same certified stone. Brilliant Earth lists it at HK$30,677. 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.
