About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551200456. Listed at 22 retailers as of November 4, 2026, with prices from HK$25,918 to HK$54,744, a HK$28,826 spread on the same certified stone. MOH London lists it at HK$54,744. 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.
