Listed at 11 retailers as of October 25, 2026, with prices from $218 to $1,265, a $1,047 spread on the same certified stone. MOH London lists it at $1,265. 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.
