This 0.9ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG569304118 or 569304118. Listed at 4 retailers as of October 30, 2026, with prices from HK$3,868 to HK$5,335, a HK$1,467 spread on the same certified stone. Kay Jewelers lists it at HK$5,335. 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.
