About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2407158165. Listed at 16 retailers as of November 2, 2026, with prices from HK$8,267 to HK$21,385, a HK$13,119 spread on the same certified stone. Moon Ocean lists it at HK$21,385. 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.
