About this 1ct natural heart diamond

This 1ct natural heart sits in the classic one-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6561126118. Listed at 15 retailers as of November 5, 2026, with prices from $1,693 to $5,547, a $3,854 spread on the same certified stone. NZ Jewellers lists it at $5,547. 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.
