About this 1.59ct natural asscher diamond

This 1.59ct natural asscher sits in the one-and-a-half to two carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3565306132. Listed at 21 retailers as of October 30, 2026, with prices from £3,684 to £7,360, a £3,676 spread on the same certified stone. NZ Jewellers lists it at £7,360. 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.
