About this 3.07ct natural radiant diamond

This 3.07ct natural radiant sits in the three to five carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5553222722. Listed at 3 retailers as of November 3, 2026, with prices from £21,677 to £25,513, a £3,836 spread on the same certified stone. Blue Nile lists it at £25,513. 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.
