About this 1.2ct natural marquise diamond

This 1.2ct natural marquise sits in the classic one-carat band, graded F colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1558604351. Listed at 4 retailers as of November 5, 2026, with prices from HK$56,070 to HK$66,355, a HK$10,285 spread on the same certified stone. Blue Nile lists it at HK$66,355. 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.
