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 very-good cut grade and certified by IGI 791618046. Listed at 12 retailers as of October 30, 2026, with prices from $1,407 to $4,150, a $2,743 spread on the same certified stone. NZ Jewellers lists it at $4,150. 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.
