About this 1.02ct natural cushion diamond

This 1.02ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1377923611. Listed at 11 retailers as of November 6, 2026, with prices from HK$12,916 to HK$20,293, a HK$7,377 spread on the same certified stone. Yorxs lists it at HK$20,293. 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.
