About this 0.9ct natural heart diamond

This 0.9ct natural heart sits in the just-under-one-carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 746532738. Listed at 17 retailers as of October 30, 2026, with prices from $1,441 to $3,810, a $2,369 spread on the same certified stone. NZ Jewellers lists it at $3,810. 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.
