About this 1.26ct natural heart diamond

This 1.26ct natural heart sits in the one-and-a-quarter to one-and-a-half carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2556091386. Listed at 15 retailers as of November 5, 2026, with prices from $3,774 to $9,047, a $5,273 spread on the same certified stone. NZ Jewellers lists it at $9,047. 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.
