About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded I 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 5373922170. Listed at 17 retailers as of November 2, 2026, with prices from HK$15,229 to HK$22,120, a HK$6,891 spread on the same certified stone. Yorxs lists it at HK$22,120. 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.
