About this 0.51ct natural asscher diamond

This 0.51ct natural asscher sits in the half to three-quarter carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6425525757. Listed at 12 retailers as of November 4, 2026, with prices from £428 to £1,037, a £609 spread on the same certified stone. MOH London lists it at £1,037. 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.
