About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6532133207. Listed at 10 retailers as of November 5, 2026, with prices from $3,569 to $8,459, a $4,890 spread on the same certified stone. NZ Jewellers lists it at $8,459. 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.
