About this 0.43ct natural cushion diamond

This 0.43ct natural cushion sits in the sub-half-carat band, graded E 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 6552629529. Listed at 11 retailers as of October 27, 2026, with prices from £324 to £794, a £470 spread on the same certified stone. Diamond Quarter lists it at £794. 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.
