Listed at 6 retailers as of October 26, 2026, with prices from £373 to £1,047, a £674 spread on the same certified stone. MOH London lists it at £1,047. 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.
