About this 1.5ct natural marquise diamond

This 1.5ct natural marquise sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7542187299. Listed at 21 retailers as of November 5, 2026, with prices from HK$56,312 to HK$121,174, a HK$64,862 spread on the same certified stone. NZ Jewellers lists it at HK$121,174. 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.
