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 €1,720 to €4,351, a €2,632 spread on the same certified stone. NZ Jewellers lists it at €4,351. 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.
