About this 1.63ct natural heart diamond

This 1.63ct natural heart sits in the one-and-a-half to two 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 6432039096. Listed at 17 retailers as of October 30, 2026, with prices from $3,846 to $8,471, a $4,625 spread on the same certified stone. NZ Jewellers lists it at $8,471. 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.
