About this 1.7ct natural oval diamond

This 1.7ct natural oval sits in the one-and-a-half to two carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI 768663715. Listed at 11 retailers as of November 5, 2026, with prices from $4,497 to $10,501, a $6,003 spread on the same certified stone. NZ Jewellers lists it at $10,501. 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.
