About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5546223817. Listed at 15 retailers as of November 2, 2026, with prices from HK$48,161 to HK$81,848, a HK$33,687 spread on the same certified stone. MOH London lists it at HK$81,848. 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.
