This 1.7ct natural oval sits in the one-and-a-half to two carat band, graded L colour (faint-tinted) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 539243286. Listed at 10 retailers as of November 4, 2026, with prices from £1,320 to £3,564, a £2,244 spread on the same certified stone. NZ Jewellers lists it at £3,564. 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.
