About this 3.03ct natural heart diamond

This 3.03ct natural heart sits in the three to five carat band, graded J 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 200000047209. Listed at 10 retailers as of November 4, 2026, with prices from £10,223 to £14,662, a £4,439 spread on the same certified stone. My Antwerp Diamonds lists it at £14,662. 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.
