About this 1.7ct natural oval diamond

This 1.7ct natural oval sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1429722988. Listed at 18 retailers as of November 2, 2026, with prices from $16,351 to $31,282, a $14,931 spread on the same certified stone. NZ Jewellers lists it at $31,282. 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.
