About this 0.91ct natural radiant diamond

This 0.91ct natural radiant sits in the just-under-one-carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1215215357. Listed at 11 retailers as of October 28, 2026, with prices from $4,017 to $6,009, a $1,991 spread on the same certified stone. The Diamond Guys lists it at $6,009. 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.
