About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded I 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 2235994080. Listed at 11 retailers as of November 3, 2026, with prices from HK$52,590 to HK$101,246, a HK$48,657 spread on the same certified stone. NZ Jewellers lists it at HK$101,246. 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.
