About this 1.01ct natural heart diamond

This 1.01ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 806601718. Listed at 9 retailers as of October 30, 2026, with prices from £1,018 to £3,271, a £2,253 spread on the same certified stone. NZ Jewellers lists it at £3,271. 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.
