This 1.63ct 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 835638860. Listed at 14 retailers as of November 5, 2026, with prices from $3,909 to $10,365, a $6,456 spread on the same certified stone. NZ Jewellers lists it at $10,365. 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.
