About this 1.02ct natural cushion diamond

This 1.02ct natural cushion sits in the classic one-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 6391854246. Listed at 22 retailers as of November 2, 2026, with prices from $3,377 to $7,144, a $3,767 spread on the same certified stone. MOH London lists it at $7,144. 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.
