About this 1ct natural radiant diamond

This 1ct 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 2175389799. Listed at 4 retailers as of November 6, 2026, with prices from $1,952 to $2,940, a $988 spread on the same certified stone. 77 Diamonds lists it at $2,940. 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.
