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 SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 7456895999. Listed at 13 retailers as of November 6, 2026, with prices from $4,503 to $8,976, a $4,473 spread on the same certified stone. MOH London lists it at $8,976. 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.
