About this 1.21ct natural marquise diamond

This 1.21ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2235875742. Listed at 7 retailers as of November 5, 2026, with prices from HK$30,190 to HK$41,860, a HK$11,670 spread on the same certified stone. Cape Diamonds lists it at HK$41,860. 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.
