About this 1.21ct natural cushion diamond

This 1.21ct 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 2476151644. Listed at 14 retailers as of November 1, 2026, with prices from HK$8,838 to HK$20,816, a HK$11,978 spread on the same certified stone. MOH London lists it at HK$20,816. 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.
