Listed at 12 retailers as of October 29, 2026, with prices from £448 to £3,113, a £2,665 spread on the same certified stone. MOH London lists it at £3,113. 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.
