This 5.16ct lab-grown cushion sits in the over five carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG680520468 or 680520468. Listed at 17 retailers as of November 1, 2026, with prices from HK$29,493 to HK$140,079, a HK$110,586 spread on the same certified stone. Novita Diamonds lists it at HK$140,079. 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.
