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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2556551367. Listed at 14 retailers as of November 5, 2026, with prices from £1,013 to £3,145, a £2,132 spread on the same certified stone. NZ Jewellers lists it at £3,145. 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.
