About this 1.31ct natural round diamond

This 1.31ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded H colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by GIA 5231974938. Listed at 8 retailers as of October 30, 2026, with prices from HK$19,057 to HK$42,100, a HK$23,043 spread on the same certified stone. NZ Jewellers lists it at HK$42,100. 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.
