About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2407506829. Listed at 14 retailers as of October 31, 2026, with prices from HK$7,516 to HK$26,194, a HK$18,678 spread on the same certified stone. Moon Ocean lists it at HK$26,194. 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.
