About this 1.51ct natural marquise diamond

This 1.51ct 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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551072778. Listed at 9 retailers as of November 2, 2026, with prices from HK$45,343 to HK$85,295, a HK$39,952 spread on the same certified stone. NZ Jewellers lists it at HK$85,295. 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.
