About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 5543183579. Listed at 15 retailers as of November 4, 2026, with prices from $2,026 to $3,975, a $1,949 spread on the same certified stone. MOH London lists it at $3,975. 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.
