About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5556221606. Listed at 13 retailers as of November 5, 2026, with prices from HK$39,603 to HK$83,826, a HK$44,223 spread on the same certified stone. NZ Jewellers lists it at HK$83,826. 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.
