About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by GIA 6541690790. Listed at 21 retailers as of November 1, 2026, with prices from €3,024 to €7,205, a €4,181 spread on the same certified stone. NZ Jewellers lists it at €7,205. 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.
