About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2544781019. Listed at 17 retailers as of November 4, 2026, with prices from HK$18,081 to HK$40,481, a HK$22,400 spread on the same certified stone. MOH London lists it at HK$40,481. 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.
