About this 1.71ct natural oval diamond

This 1.71ct natural oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade and certified by IGI 790691116. Listed at 16 retailers as of November 2, 2026, with prices from $8,385 to $18,563, a $10,178 spread on the same certified stone. NZ Jewellers lists it at $18,563. 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.
