This 1.7ct natural round 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 and certified by GIA 7452842536. Listed at 18 retailers as of October 30, 2026, with prices from $13,517 to $25,805, a $12,289 spread on the same certified stone. NZ Jewellers lists it at $25,805. 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.
