When she visited in November 1967, she was the Queen of Malta, Malta having maintained her as head of state after gaining independence from Britain in 1964. (This lasted until 1974, when they became a republic.)
Video: The Queen's visit highlightsMany of the jewels brought along for the trip were pretty standard state visit picks, such as the Dorset Bow Brooch and the Cullinan V Brooch (worn with a sparkling badge underneath), but there were also some interesting and relatively new pieces at play.
Brazilian Aquamarine Parure on this trip, at a time when it looked slightly different - she wouldn't have the tiara modified to its current format until 1971. (She was also wearing her Garter insignia and Royal Family Orders, of course.)
She also selected one of her favorite sparkling suites of jewelry to open Malta's parliament in grand style: Queen Alexandra's Kokoshnik Tiara, the Greville Chandelier Earrings, the George VI Festoon Necklace, and Queen Mary's Chain-Link Bracelet.
The Queen and The Duke of Edinburgh's next trip to Malta is fast approaching: they'll travel there in late November for the 2015 session of the Commonwealth Heads of Government Meeting. The Prince of Wales and The Duchess of Cornwall will also be along for the ride.
