About this 1.31ct natural heart diamond

This 1.31ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2568437370. Listed at 17 retailers as of October 30, 2026, with prices from HK$16,169 to HK$45,052, a HK$28,883 spread on the same certified stone. NZ Jewellers lists it at HK$45,052. 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.
