About this 1.7ct natural heart diamond

This 1.7ct natural heart sits in the one-and-a-half to two carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1449071295. Listed at 17 retailers as of October 30, 2026, with prices from $11,032 to $24,317, a $13,285 spread on the same certified stone. NZ Jewellers lists it at $24,317. 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.
