About this 1.21ct natural oval diamond

This 1.21ct natural oval 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 2557969790. Listed at 8 retailers as of November 2, 2026, with prices from HK$25,777 to HK$55,073, a HK$29,295 spread on the same certified stone. MOH London lists it at HK$55,073. 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.
