About this 1.54ct natural oval diamond

This 1.54ct natural oval sits in the one-and-a-half to two carat band, graded I colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 717514656. Listed at 17 retailers as of November 5, 2026, with prices from £2,217 to £4,691, a £2,474 spread on the same certified stone. NZ Jewellers lists it at £4,691. 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.
