About this 1.21ct natural radiant diamond

This 1.21ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and VVS1 clarity (very-very-slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1255238625. Listed at 5 retailers as of November 1, 2026, with prices from $3,056 to $4,649, a $1,593 spread on the same certified stone. 77 Diamonds lists it at $4,649. 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.
