About this 1.03ct natural cushion diamond

This 1.03ct 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 1398080275. Listed at 14 retailers as of November 4, 2026, with prices from HK$11,991 to HK$29,174, a HK$17,182 spread on the same certified stone. MOH London lists it at HK$29,174. 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.
