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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7538718383. Listed at 7 retailers as of November 4, 2026, with prices from £1,325 to £2,985, a £1,660 spread on the same certified stone. MOH London lists it at £2,985. 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.
