About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 6542761928. Listed at 21 retailers as of October 30, 2026, with prices from HK$30,096 to HK$71,741, a HK$41,645 spread on the same certified stone. NZ Jewellers lists it at HK$71,741. 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.
