About this 0.91ct natural heart diamond

This 0.91ct natural heart sits in the just-under-one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2195159757. Listed at 8 retailers as of October 30, 2026, with prices from $4,218 to $10,088, a $5,870 spread on the same certified stone. NZ Jewellers lists it at $10,088. 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.
