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 SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2354093239. Listed at 15 retailers as of November 4, 2026, with prices from HK$12,132 to HK$28,557, a HK$16,424 spread on the same certified stone. MOH London lists it at HK$28,557. 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.
