About this 1.21ct natural asscher diamond

This 1.21ct natural asscher sits in the classic one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5241030106. Listed at 12 retailers as of November 4, 2026, with prices from £2,945 to £5,525, a £2,580 spread on the same certified stone. MOH London lists it at £5,525. 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.
