About this 1.5ct natural oval diamond

This 1.5ct 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 stated by the retailer rather than the lab and certified by GIA 7446303146. Listed at 25 retailers as of November 4, 2026, with prices from £3,846 to £8,737, a £4,891 spread on the same certified stone. NZ Jewellers lists it at £8,737. 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.
