About this 0.3ct natural cushion diamond

This 0.3ct natural cushion sits in the sub-half-carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 3545103512. Listed at 16 retailers as of November 2, 2026, with prices from $338 to $1,064, a $726 spread on the same certified stone. MOH London lists it at $1,064. 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.
