Listed at 11 retailers as of November 4, 2026, with prices from £364 to £2,982, a £2,618 spread on the same certified stone. MOH London lists it at £2,982. 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.
