About this 1.56ct natural oval diamond

This 1.56ct natural oval sits in the one-and-a-half to two carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade and certified by IGI 384954498. Listed at 10 retailers as of October 28, 2026, with prices from £4,329 to £9,218, a £4,889 spread on the same certified stone. NZ Jewellers lists it at £9,218. 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.
