About this 1.6ct natural heart diamond

This 1.6ct natural heart sits in the one-and-a-half to two carat band, graded J colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 673408427. Listed at 11 retailers as of November 5, 2026, with prices from $3,964 to $8,098, a $4,134 spread on the same certified stone. NZ Jewellers lists it at $8,098. 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.
