About this 1.02ct natural heart diamond

This 1.02ct 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 1543677273. Listed at 14 retailers as of November 5, 2026, with prices from £970 to £3,256, a £2,285 spread on the same certified stone. NZ Jewellers lists it at £3,256. 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.
