About this 1.03ct natural heart diamond

This 1.03ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 190000107469. Listed at 11 retailers as of November 5, 2026, with prices from £1,895 to £4,422, a £2,527 spread on the same certified stone. NZ Jewellers lists it at £4,422. 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.
