About this 1.21ct natural asscher diamond

This 1.21ct natural asscher sits in the classic one-carat band, graded I 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 1242116117. Listed at 8 retailers as of November 4, 2026, with prices from £1,673 to £3,361, a £1,688 spread on the same certified stone. MOH London lists it at £3,361. 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.
