About this 1.01ct natural heart diamond

This 1.01ct natural heart sits in the classic one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6551881534. Listed at 19 retailers as of November 5, 2026, with prices from £1,023 to £3,257, a £2,235 spread on the same certified stone. NZ Jewellers lists it at £3,257. 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.
