This 2.59ct lab-grown cushion sits in the two to three carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG728517095 or 728517095. Listed at 18 retailers as of October 28, 2026, with prices from HK$9,447 to HK$48,883, a HK$39,436 spread on the same certified stone. Brilliant Earth lists it at HK$48,883. 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.
