Listed at 16 retailers as of November 2, 2026, with prices from $413 to $1,839, a $1,426 spread on the same certified stone. MOH London lists it at $1,839. 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.
