About this 1.7ct natural marquise diamond

This 1.7ct natural marquise sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3555196465. Listed at 3 retailers as of November 1, 2026, with prices from HK$94,764 to HK$115,900, a HK$21,136 spread on the same certified stone. 77 Diamonds lists it at HK$115,900. 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.
