About this 1.51ct natural marquise diamond

This 1.51ct natural marquise sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6452767979. Listed at 12 retailers as of October 30, 2026, with prices from HK$86,072 to HK$160,186, a HK$74,114 spread on the same certified stone. NZ Jewellers lists it at HK$160,186. 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.
