About this 1.2ct natural cushion diamond

This 1.2ct 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 6485076886. Listed at 19 retailers as of November 2, 2026, with prices from HK$17,238 to HK$37,994, a HK$20,757 spread on the same certified stone. MOH London lists it at HK$37,994. 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.
