Listed at 18 retailers as of November 1, 2026, with prices from $515 to $2,232, a $1,716 spread on the same certified stone. MOH London lists it at $2,232. 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.
