About this 0.41ct natural cushion diamond

This 0.41ct natural cushion sits in the sub-half-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6522411001. Listed at 13 retailers as of November 4, 2026, with prices from £430 to £1,017, a £587 spread on the same certified stone. MOH London lists it at £1,017. 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.
