About this 1.2ct natural heart diamond

This 1.2ct natural heart sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2558092949. Listed at 7 retailers as of November 3, 2026, with prices from $3,516 to $7,612, a $4,095 spread on the same certified stone. NZ Jewellers lists it at $7,612. 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.
