About this 1.7ct natural marquise diamond

This 1.7ct natural marquise sits in the one-and-a-half to two carat band, graded M colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1559568817. Listed at 7 retailers as of November 4, 2026, with prices from HK$23,183 to HK$38,750, a HK$15,567 spread on the same certified stone. Wholesale Diamonds Direct lists it at HK$38,750. 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.
