About this 1.21ct natural asscher diamond

This 1.21ct natural asscher sits in the classic one-carat band, graded H colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6402830600. Listed at 6 retailers as of November 4, 2026, with prices from £3,759 to £6,077, a £2,318 spread on the same certified stone. MOH London lists it at £6,077. 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.
