Listed at 3 retailers as of October 29, 2026, with prices from $1,248 to $3,377, a $2,128 spread on the same certified stone. Brilliant Earth lists it at $3,377. 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.
