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 I colour (near-colourless) and I1 clarity (included), with a very-good cut grade and certified by GIA 5396709488. Listed at 9 retailers as of October 30, 2026, with prices from €1,971 to €5,511, a €3,540 spread on the same certified stone. NZ Jewellers lists it at €5,511. 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.
