About this 0.99ct natural radiant diamond

This 0.99ct natural radiant sits in the just-under-one-carat band, graded K colour (faint-tinted) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2181131750. Listed at 2 retailers as of November 6, 2026, with prices from $2,719 to $4,052, a $1,333 spread on the same certified stone. 77 Diamonds lists it at $4,052. 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.
