Listed at 11 retailers as of October 29, 2026, with prices from £344 to £1,492, a £1,148 spread on the same certified stone. MOH London lists it at £1,492. 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.
