About this 1.51ct natural marquise diamond

This 1.51ct 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 standard cut grade stated by the retailer rather than the lab and certified by GIA 7556154054. Listed at 8 retailers as of November 3, 2026, with prices from HK$60,473 to HK$115,978, a HK$55,504 spread on the same certified stone. NZ Jewellers lists it at HK$115,978. 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.
