About this 1.03ct natural heart diamond

This 1.03ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 746534103. Listed at 12 retailers as of November 5, 2026, with prices from $2,797 to $7,108, a $4,311 spread on the same certified stone. NZ Jewellers lists it at $7,108. 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.
