About this 1.21ct natural heart diamond

This 1.21ct 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 7548099120. Listed at 8 retailers as of October 30, 2026, with prices from €1,800 to €4,095, a €2,295 spread on the same certified stone. NZ Jewellers lists it at €4,095. 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.
