About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2564212519. Listed at 19 retailers as of November 5, 2026, with prices from HK$25,378 to HK$59,345, a HK$33,967 spread on the same certified stone. NZ Jewellers lists it at HK$59,345. 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.
