About this 0.78ct natural cushion diamond

This 0.78ct natural cushion sits in the just-under-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 7356351382. Listed at 4 retailers as of November 4, 2026, with prices from $2,621 to $4,261, a $1,640 spread on the same certified stone. MOH London lists it at $4,261. 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.
