About this 1ct natural cushion diamond

This 1ct natural cushion sits in the classic 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 7421786854. Listed at 13 retailers as of November 4, 2026, with prices from HK$9,538 to HK$19,867, a HK$10,329 spread on the same certified stone. MOH London lists it at HK$19,867. 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.
