This 1.22ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI LG840622278 or 840622278. Listed at 17 retailers as of November 4, 2026, with prices from HK$2,832 to HK$15,645, a HK$12,812 spread on the same certified stone. Helzberg Diamonds lists it at HK$15,645. 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.
