About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2557770054. Listed at 20 retailers as of November 4, 2026, with prices from HK$37,980 to HK$70,630, a HK$32,650 spread on the same certified stone. MOH London lists it at HK$70,630. 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.
