About this 0.8ct natural radiant diamond

This 0.8ct natural radiant sits in the just-under-one-carat band, graded I colour (near-colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1555685976. Listed at 8 retailers as of November 2, 2026, with prices from $1,179 to $1,627, a $448 spread on the same certified stone. Jared lists it at $1,627. 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.
