About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded G colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 851659463. Listed at 3 retailers as of November 6, 2026, with prices from $5,173 to $6,326, a $1,153 spread on the same certified stone. The Perfect Carat lists it at $6,326. 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.
