About this 1.01ct natural heart diamond

This 1.01ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 805628218. Listed at 12 retailers as of November 5, 2026, with prices from £1,230 to £3,647, a £2,417 spread on the same certified stone. NZ Jewellers lists it at £3,647. 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.
