About this 0.63ct natural radiant diamond

This 0.63ct natural radiant sits in the half to three-quarter carat band, graded E colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 6552272951. Listed at 8 retailers as of October 28, 2026, with prices from $999 to $1,386, a $386 spread on the same certified stone. Jared lists it at $1,386. 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.
