About this 1.01ct natural radiant diamond

This 1.01ct natural radiant sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6551666166. Listed at 7 retailers as of November 2, 2026, with prices from £3,289 to £4,357, a £1,068 spread on the same certified stone. GS Diamonds lists it at £4,357. 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.
