About this 1.21ct natural radiant diamond

This 1.21ct natural radiant sits in the classic one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 7551262443. Listed at 10 retailers as of November 5, 2026, with prices from $3,851 to $6,854, a $3,003 spread on the same certified stone. Wholesale Diamonds Direct lists it at $6,854. 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.
