Listed at 16 retailers as of November 3, 2026, with prices from £273 to £1,324, a £1,050 spread on the same certified stone. MOH London lists it at £1,324. 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.
