About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2567197770. Listed at 14 retailers as of November 5, 2026, with prices from HK$19,468 to HK$35,425, a HK$15,957 spread on the same certified stone. Helzberg Diamonds lists it at HK$35,425. 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.
