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 VS1 clarity (very-slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1448487257. Listed at 3 retailers as of November 1, 2026, with prices from $3,862 to $5,101, a $1,239 spread on the same certified stone. 77 Diamonds lists it at $5,101. 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.
