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 1146647770. Listed at 8 retailers as of November 6, 2026, with prices from HK$32,306 to HK$43,576, a HK$11,270 spread on the same certified stone. Jared lists it at HK$43,576. 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.
