About this 1.25ct natural round diamond

This 1.25ct natural round sits in the one-and-a-quarter to one-and-a-half carat band, graded J colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by GIA 6415581706. Listed at 10 retailers as of October 31, 2026, with prices from €1,426 to €3,026, a €1,600 spread on the same certified stone. MOH London lists it at €3,026. 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.
