About this 1ct natural radiant diamond

This 1ct natural radiant sits in the classic one-carat band, graded I colour (near-colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5513129259. Listed at 5 retailers as of November 4, 2026, with prices from $1,946 to $2,336, a $390 spread on the same certified stone. Blue Nile lists it at $2,336. 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.
