About this 1ct natural asscher diamond

This 1ct natural asscher sits in the classic one-carat band, graded J 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 7522735574. Listed at 8 retailers as of October 31, 2026, with prices from £587 to £738, a £151 spread on the same certified stone. Michael Trio lists it at £738. 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.
