About this 0.77ct natural radiant diamond

This 0.77ct natural radiant sits in the just-under-one-carat band, graded J 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 15304220. Listed at 2 retailers as of November 1, 2026, with prices from $4,099 to $6,052, a $1,954 spread on the same certified stone. 77 Diamonds lists it at $6,052. 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.
