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 very-good cut grade stated by the retailer rather than the lab and certified by GIA 2556445940. Listed at 16 retailers as of October 26, 2026, with prices from $420 to $927, a $507 spread on the same certified stone. MOH London lists it at $927. 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.
