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 789604444. Listed at 11 retailers as of November 4, 2026, with prices from $2,222 to $6,089, a $3,867 spread on the same certified stone. NZ Jewellers lists it at $6,089. 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.
