About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded G 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 6183371945. Listed at 10 retailers as of November 4, 2026, with prices from $4,242 to $6,461, a $2,219 spread on the same certified stone. 77 Diamonds lists it at $6,461. 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.
