About this 0.9ct natural heart diamond

This 0.9ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 671474664. Listed at 17 retailers as of October 30, 2026, with prices from $1,832 to $4,843, a $3,011 spread on the same certified stone. NZ Jewellers lists it at $4,843. 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.
