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 2568608905. Listed at 15 retailers as of November 1, 2026, with prices from HK$107,785 to HK$193,187, a HK$85,402 spread on the same certified stone. With Clarity lists it at HK$193,187. 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.
