About this 1.7ct natural oval diamond

This 1.7ct 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 758570994. Listed at 15 retailers as of November 1, 2026, with prices from £5,056 to £10,117, a £5,061 spread on the same certified stone. NZ Jewellers lists it at £10,117. 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.
