About this 2.51ct natural asscher diamond

This 2.51ct natural asscher sits in the two to three 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 1525399708. Listed at 5 retailers as of November 1, 2026, with prices from £17,265 to £22,048, a £4,783 spread on the same certified stone. 77 Diamonds lists it at £22,048. 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.
