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 D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1508017639. Listed at 4 retailers as of November 2, 2026, with prices from £2,930 to £5,024, a £2,094 spread on the same certified stone. MOH London lists it at £5,024. 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.
