This 1.33ct lab-grown cushion sits in the one-and-a-quarter to one-and-a-half carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG831696418 or 831696418. Listed at 17 retailers as of October 30, 2026, with prices from HK$4,982 to HK$16,868, a HK$11,886 spread on the same certified stone. Helzberg Diamonds lists it at HK$16,868. 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.
