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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1335609275. Listed at 13 retailers as of November 5, 2026, with prices from $2,357 to $6,778, a $4,421 spread on the same certified stone. NZ Jewellers lists it at $6,778. 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.
