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 SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1555999788. Listed at 15 retailers as of October 30, 2026, with prices from HK$51,821 to HK$114,490, a HK$62,670 spread on the same certified stone. NZ Jewellers lists it at HK$114,490. 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.
