About this 3.1ct natural radiant diamond

This 3.1ct natural radiant sits in the three to five carat band, graded I 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 1563741619. Listed at 7 retailers as of November 5, 2026, with prices from £15,664 to £19,740, a £4,076 spread on the same certified stone. Adiamor lists it at £19,740. 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.
