About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6371888168. Listed at 14 retailers as of October 29, 2026, with prices from HK$15,308 to HK$22,236, a HK$6,928 spread on the same certified stone. Yorxs lists it at HK$22,236. 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.
