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 $4,320 to $9,138, a $4,819 spread on the same certified stone. NZ Jewellers lists it at $9,138. 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.
