About this 1.01ct natural round diamond

This 1.01ct natural round sits in the classic one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI 626482613. Listed at 20 retailers as of November 5, 2026, with prices from £857 to £3,206, a £2,349 spread on the same certified stone. NZ Jewellers lists it at £3,206. 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.
