About this 1.7ct natural heart diamond

This 1.7ct natural heart sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 662419788. Listed at 16 retailers as of October 30, 2026, with prices from $7,628 to $14,627, a $7,000 spread on the same certified stone. NZ Jewellers lists it at $14,627. 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.
