About this 1.5ct natural marquise diamond

This 1.5ct 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 standard cut grade stated by the retailer rather than the lab and certified by GIA 2556768747. Listed at 2 retailers as of November 3, 2026, with prices from HK$23,214 to HK$29,016, a HK$5,802 spread on the same certified stone. Yorxs lists it at HK$29,016. 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.
