About this 0.9ct natural radiant diamond

This 0.9ct 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 6552147341. Listed at 16 retailers as of October 30, 2026, with prices from $1,403 to $3,633, a $2,230 spread on the same certified stone. Moon Ocean lists it at $3,633. 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.
