About this 1ct natural asscher diamond

This 1ct natural asscher sits in the classic one-carat band, graded H 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 6551437712. Listed at 7 retailers as of October 29, 2026, with prices from £858 to £1,649, a £791 spread on the same certified stone. MOH London lists it at £1,649. 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.
