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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6442782280. Listed at 20 retailers as of October 30, 2026, with prices from HK$22,496 to HK$52,451, a HK$29,955 spread on the same certified stone. NZ Jewellers lists it at HK$52,451. 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.
