About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3525877639. Listed at 5 retailers as of November 7, 2026, with prices from HK$25,119 to HK$45,269, a HK$20,150 spread on the same certified stone. NZ Jewellers lists it at HK$45,269. 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.
