About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2554854633. Listed at 15 retailers as of October 30, 2026, with prices from HK$53,197 to HK$116,209, a HK$63,012 spread on the same certified stone. NZ Jewellers lists it at HK$116,209. 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.
