This 1.02ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 801639536. Listed at 14 retailers as of November 2, 2026, with prices from £790 to £2,154, a £1,363 spread on the same certified stone. NZ Jewellers lists it at £2,154. 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.
