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 €3,434 to €8,185, a €4,751 spread on the same certified stone. NZ Jewellers lists it at €8,185. 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.
