Though the piece was once said to date from the 18th century, the Spencer tiara is actually made up of other pieces of jewellery of varying ages and from different jewellers that has gone through several changes over time. The oldest parts of the tiara are the ends. They are said to have come from a tiara that once belonged to Frances Manby, the last Viscountess Montagu, and left to Lady Sarah Spencer in 1875.[1][page needed] The centre element was a wedding present from Lady Sarah Isabella Spencer to Cynthia, Viscountess Althorp (Diana's grandmother), when she married Albert, Viscount Althorp, the future 7th Earl Spencer, in 1919.
