About this 1.23ct natural asscher diamond

This 1.23ct natural asscher sits in the classic one-carat band, graded F 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 5231298630. Listed at 6 retailers as of November 4, 2026, with prices from $7,748 to $13,597, a $5,849 spread on the same certified stone. MOH London lists it at $13,597. 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.
