About this 0.9ct natural cushion diamond

This 0.9ct natural cushion sits in the just-under-one-carat band, graded J 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 6265325423. Listed at 20 retailers as of November 1, 2026, with prices from $3,114 to $6,882, a $3,768 spread on the same certified stone. MOH London lists it at $6,882. 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.
