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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1535791409. Listed at 16 retailers as of October 30, 2026, with prices from $3,669 to $8,429, a $4,760 spread on the same certified stone. NZ Jewellers lists it at $8,429. 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.
