Listed at 8 retailers as of November 4, 2026, with prices from $347 to $2,115, a $1,768 spread on the same certified stone. MOH London lists it at $2,115. 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.
