About this 0.81ct natural radiant diamond

This 0.81ct natural radiant sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1558508791. Listed at 8 retailers as of October 28, 2026, with prices from $1,715 to $2,392, a $676 spread on the same certified stone. Jared lists it at $2,392. 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.
