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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1565578236. Listed at 15 retailers as of November 1, 2026, with prices from HK$84,932 to HK$152,199, a HK$67,267 spread on the same certified stone. With Clarity lists it at HK$152,199. 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.
