Listed at 17 retailers as of October 26, 2026, with prices from $728 to $3,926, a $3,198 spread on the same certified stone. MOH London lists it at $3,926. 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.
