About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded G 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 3555246295. Listed at 19 retailers as of October 30, 2026, with prices from HK$78,532 to HK$141,073, a HK$62,541 spread on the same certified stone. NZ Jewellers lists it at HK$141,073. 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.
