About this 1.02ct natural heart diamond

This 1.02ct natural heart sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 808619710. Listed at 13 retailers as of November 4, 2026, with prices from $2,159 to $5,686, a $3,527 spread on the same certified stone. NZ Jewellers lists it at $5,686. 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.
