This 1ct lab-grown cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG766659411 or 766659411. Listed at 8 retailers as of November 4, 2026, with prices from HK$2,226 to HK$6,330, a HK$4,105 spread on the same certified stone. MOH London lists it at HK$6,330. 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.
