Listed at 18 retailers as of October 27, 2026, with prices from $377 to $2,140, a $1,763 spread on the same certified stone. Brilliant Earth lists it at $2,140. 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.
