About this 0.3ct natural cushion diamond

This 0.3ct natural cushion sits in the sub-half-carat band, graded G colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552708098. Listed at 11 retailers as of October 31, 2026, with prices from $232 to $758, a $526 spread on the same certified stone. MOH London lists it at $758. 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.
