Listed at 5 retailers as of November 4, 2026, with prices from £460 to £1,150, a £690 spread on the same certified stone. MOH London lists it at £1,150. 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.
