About this 1.2ct natural radiant diamond

This 1.2ct natural radiant sits in the classic one-carat band, graded K colour (faint-tinted) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2554821058. Listed at 10 retailers as of November 4, 2026, with prices from $1,760 to $2,937, a $1,178 spread on the same certified stone. Wholesale Diamonds Direct lists it at $2,937. 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.
