About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded I 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 5303799521. Listed at 13 retailers as of November 1, 2026, with prices from HK$14,361 to HK$33,908, a HK$19,547 spread on the same certified stone. MOH London lists it at HK$33,908. 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.
