About this 1.03ct natural marquise diamond

This 1.03ct natural marquise sits in the classic one-carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by HRD 260000145348. Listed at 5 retailers as of November 3, 2026, with prices from £1,066 to £2,601, a £1,535 spread on the same certified stone. NZ Jewellers lists it at £2,601. 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.
