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 SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 2554597321. Listed at 7 retailers as of November 4, 2026, with prices from $1,372 to $2,231, a $859 spread on the same certified stone. Wholesale Diamonds Direct lists it at $2,231. 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.
