About this 1.7ct natural heart diamond

This 1.7ct natural heart sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 6445201943. Listed at 20 retailers as of October 30, 2026, with prices from $7,327 to $17,669, a $10,342 spread on the same certified stone. NZ Jewellers lists it at $17,669. 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.
