This 2.57ct lab-grown cushion sits in the two to three carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG529263226 or 529263226. Listed at 8 retailers as of November 5, 2026, with prices from HK$5,525 to HK$15,070, a HK$9,544 spread on the same certified stone. MOH London lists it at HK$15,070. 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.
