About this 1.02ct natural radiant diamond

This 1.02ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 800655117. Listed at 14 retailers as of October 27, 2026, with prices from $3,055 to $5,996, a $2,941 spread on the same certified stone. NZ Jewellers lists it at $5,996. 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.
