About this 3.1ct natural radiant diamond

This 3.1ct natural radiant sits in the three to five carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 15878515. Listed at 3 retailers as of November 1, 2026, with prices from £31,147 to £43,476, a £12,329 spread on the same certified stone. Cape Diamonds lists it at £43,476. 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.
