About this 1.51ct natural round diamond

This 1.51ct natural round sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 646462155. Listed at 17 retailers as of October 30, 2026, with prices from €3,229 to €7,142, a €3,913 spread on the same certified stone. NZ Jewellers lists it at €7,142. 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.
