About this 1.2ct natural cushion diamond

This 1.2ct natural cushion sits in the classic one-carat band, graded I 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 5423877179. Listed at 21 retailers as of November 4, 2026, with prices from $4,336 to $10,027, a $5,692 spread on the same certified stone. MOH London lists it at $10,027. 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.
