About this 1.21ct natural cushion diamond

This 1.21ct natural cushion sits in the classic one-carat band, graded I 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 6302486253. Listed at 6 retailers as of October 31, 2026, with prices from $3,130 to $4,770, a $1,640 spread on the same certified stone. 77 Diamonds lists it at $4,770. 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.
