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 GIA 2566326143. Listed at 21 retailers as of November 5, 2026, with prices from $3,437 to $9,775, a $6,338 spread on the same certified stone. NZ Jewellers lists it at $9,775. 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.
