About this 0.77ct natural radiant diamond

This 0.77ct natural radiant sits in the just-under-one-carat band, graded F colour (colourless) and IF clarity (flawless or internally-flawless), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1555601399. Listed at 3 retailers as of November 2, 2026, with prices from $1,730 to $1,999, a $269 spread on the same certified stone. Blue Nile lists it at $1,999. 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.
