About this 1.02ct natural radiant diamond

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 $1,909 to $5,201, a $3,292 spread on the same certified stone. NZ Jewellers lists it at $5,201. 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.
