About this 1.3ct natural asscher diamond

This 1.3ct natural asscher sits in the one-and-a-quarter to one-and-a-half carat band, graded I 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 5563311729. Listed at 14 retailers as of November 5, 2026, with prices from £1,841 to £4,170, a £2,329 spread on the same certified stone. NZ Jewellers lists it at £4,170. 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.
