This 0.91ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade and certified by IGI LG517283270 or 517283270. Listed at 12 retailers as of October 29, 2026, with prices from HK$1,091 to HK$10,143, a HK$9,053 spread on the same certified stone. MOH London lists it at HK$10,143. 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.
