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 $6,835 to $15,056, a $8,220 spread on the same certified stone. NZ Jewellers lists it at $15,056. 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.
