About this 1.59ct natural oval diamond

This 1.59ct natural oval sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2537057557. Listed at 26 retailers as of November 5, 2026, with prices from £5,432 to £12,251, a £6,819 spread on the same certified stone. NZ Jewellers lists it at £12,251. 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.
