About this 0.9ct natural radiant diamond

This 0.9ct natural radiant sits in the just-under-one-carat band, graded H colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 2554383755. Listed at 8 retailers as of October 28, 2026, with prices from $1,955 to $4,354, a $2,399 spread on the same certified stone. Moon Ocean lists it at $4,354. 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.
