About this 1.5ct natural marquise diamond

This 1.5ct 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 6455423519. Listed at 9 retailers as of November 1, 2026, with prices from HK$84,824 to HK$150,888, a HK$66,064 spread on the same certified stone. NZ Jewellers lists it at HK$150,888. 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.
