Listed at 13 retailers as of October 29, 2026, with prices from £98 to £640, a £542 spread on the same certified stone. MOH London lists it at £640. 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.
