About this 1.58ct natural heart diamond

This 1.58ct natural heart sits in the one-and-a-half to two 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 6565210521. Listed at 16 retailers as of November 2, 2026, with prices from $6,985 to $15,418, a $8,433 spread on the same certified stone. NZ Jewellers lists it at $15,418. 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.
