About this 0.71ct natural round diamond

This 0.71ct natural round sits in the half to three-quarter carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 660497908. Listed at 13 retailers as of November 4, 2026, with prices from £401 to £1,362, a £961 spread on the same certified stone. NZ Jewellers lists it at £1,362. 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.
