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 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 6531863019. Listed at 10 retailers as of November 5, 2026, with prices from HK$26,294 to HK$52,338, a HK$26,044 spread on the same certified stone. NZ Jewellers lists it at HK$52,338. 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.
