About this 0.3ct natural cushion diamond
This 0.3ct natural cushion sits in the sub-half-carat band, graded J 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 6542975652. Listed at 15 retailers as of November 1, 2026, with prices from €151 to €489, a €338 spread on the same certified stone. MOH London lists it at €489. 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.
