About this 1.51ct natural princess diamond

This 1.51ct natural princess sits in the one-and-a-half to two carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2231015437. Listed at 12 retailers as of October 27, 2026, with prices from HK$43,775 to HK$83,956, a HK$40,181 spread on the same certified stone. NZ Jewellers lists it at HK$83,956. 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.
