Listed at 15 retailers as of October 29, 2026, with prices from £378 to £1,971, a £1,592 spread on the same certified stone. MOH London lists it at £1,971. 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.
