About this 0.45ct natural cushion diamond

This 0.45ct natural cushion sits in the sub-half-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2336205594. Listed at 12 retailers as of November 4, 2026, with prices from £306 to £831, a £526 spread on the same certified stone. MOH London lists it at £831. 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.
