Listed at 15 retailers as of October 29, 2026, with prices from £1,441 to £11,396, a £9,956 spread on the same certified stone. Brilliant Earth lists it at £11,396. 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.
