About this 1ct natural round diamond

This 1ct natural round sits in the classic one-carat band, graded J colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 467133077. Listed at 15 retailers as of November 5, 2026, with prices from $2,433 to $5,630, a $3,197 spread on the same certified stone. NZ Jewellers lists it at $5,630. 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.
