About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a very-good cut grade and certified by IGI 646466607. Listed at 12 retailers as of November 5, 2026, with prices from $3,124 to $7,906, a $4,782 spread on the same certified stone. NZ Jewellers lists it at $7,906. 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.
