About this 1.21ct natural heart diamond

This 1.21ct natural heart sits in the classic one-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1537737014. Listed at 9 retailers as of November 5, 2026, with prices from $4,000 to $8,334, a $4,334 spread on the same certified stone. NZ Jewellers lists it at $8,334. 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.
