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 VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6565341856. Listed at 14 retailers as of October 30, 2026, with prices from $1,129 to $3,730, a $2,601 spread on the same certified stone. NZ Jewellers lists it at $3,730. 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.
