This 1ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI LG843650591 or 843650591. Listed at 10 retailers as of October 25, 2026, with prices from HK$1,185 to HK$11,000, a HK$9,816 spread on the same certified stone. MOH London lists it at HK$11,000. 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.
