About this 1.05ct natural cushion diamond

This 1.05ct natural cushion sits in the classic one-carat band, graded J colour (near-colourless) and VS1 clarity (very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1248510622. Listed at 7 retailers as of November 1, 2026, with prices from $4,147 to $6,637, a $2,490 spread on the same certified stone. MOH London lists it at $6,637. 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.
