This 0.45ct natural cushion sits in the sub-half-carat band, graded F colour (colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6522499875. Listed at 13 retailers as of November 1, 2026, with prices from £184 to £581, a £397 spread on the same certified stone. MOH London lists it at £581. 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.
