Listed at 12 retailers as of October 25, 2026, with prices from £353 to £1,919, a £1,566 spread on the same certified stone. MOH London lists it at £1,919. 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.
