This 1ct lab-grown cushion sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade and certified by IGI LG500148231 or 500148231. Listed at 6 retailers as of November 5, 2026, with prices from HK$1,803 to HK$8,709, a HK$6,907 spread on the same certified stone. MOH London lists it at HK$8,709. 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.
