About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6445956527. Listed at 14 retailers as of November 2, 2026, with prices from £1,274 to £2,803, a £1,529 spread on the same certified stone. MOH London lists it at £2,803. 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.
