About this 1.21ct natural asscher diamond

This 1.21ct natural asscher sits in the classic one-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 3545398902. Listed at 15 retailers as of November 4, 2026, with prices from £2,734 to £5,559, a £2,825 spread on the same certified stone. MOH London lists it at £5,559. 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.
