About this 1.23ct natural cushion diamond

This 1.23ct natural cushion sits in the classic one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7531894842. Listed at 3 retailers as of November 2, 2026, with prices from HK$11,662 to HK$20,952, a HK$9,290 spread on the same certified stone. MOH London lists it at HK$20,952. 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.
