About this 3.01ct natural radiant diamond

This 3.01ct natural radiant sits in the three to five carat band, graded H 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 2557628686. Listed at 3 retailers as of November 5, 2026, with prices from £15,943 to £18,939, a £2,996 spread on the same certified stone. Blue Nile lists it at £18,939. 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.
