About this 1.5ct natural oval diamond

This 1.5ct 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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 1545131846. Listed at 22 retailers as of November 5, 2026, with prices from £3,923 to £8,761, a £4,838 spread on the same certified stone. NZ Jewellers lists it at £8,761. 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.
