About this 2.51ct natural asscher diamond

This 2.51ct natural asscher sits in the two to three carat band, graded D colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2447551142. Listed at 9 retailers as of November 6, 2026, with prices from £16,046 to £20,389, a £4,343 spread on the same certified stone. GemTrove lists it at £20,389. 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.
