About this 1.7ct natural marquise diamond

This 1.7ct natural marquise sits in the one-and-a-half to two 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 7566501824. Listed at 10 retailers as of November 1, 2026, with prices from HK$90,513 to HK$156,075, a HK$65,562 spread on the same certified stone. MOH London lists it at HK$156,075. 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.
