About this 1.7ct natural radiant diamond

This 1.7ct natural radiant sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5556315668. Listed at 34 retailers as of November 5, 2026, with prices from $10,135 to $18,769, a $8,634 spread on the same certified stone. NZ Jewellers lists it at $18,769. 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.
