About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6435807278. Listed at 17 retailers as of October 30, 2026, with prices from $1,216 to $3,993, a $2,777 spread on the same certified stone. NZ Jewellers lists it at $3,993. 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.
