About this 0.99ct natural radiant diamond

This 0.99ct natural radiant sits in the just-under-one-carat band, graded E colour (colourless) and SI2 clarity (slightly-included), with a very-good cut grade stated by the retailer rather than the lab and certified by GIA 1116661523. Listed at 4 retailers as of October 28, 2026, with prices from $3,181 to $6,018, a $2,837 spread on the same certified stone. MOH London lists it at $6,018. 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.
