This 1.7ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI 739551325. Listed at 18 retailers as of November 5, 2026, with prices from $3,909 to $9,037, a $5,127 spread on the same certified stone. NZ Jewellers lists it at $9,037. 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.
