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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 3555615862. Listed at 12 retailers as of November 4, 2026, with prices from HK$21,741 to HK$41,366, a HK$19,625 spread on the same certified stone. Helzberg Diamonds lists it at HK$41,366. 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.
