Africa - Many of the kingdoms of West Africa had amazing royal regalia.  A great deal of it can be seen in museums.

In Nigeria, Yoruban descendants of the divine Oduduwa are permitted to wear "adentas" or tall beaded crowns that include beaded veils for the face and embroidered birds.  Fakes abound.

Ethiopia - The British Museum didn’t get to be fabulous by borrowing treasures.  Greece wants it’s Elgin Marbles back, and Ethiopia wants the Maqdala Ethiopian Treasures.

France - The remaining French crown jewels can be found in a small display at the Louvre Museum in Paris .  They are glorious - although Wikipedia says the crowns are now set with glass, but few in number because some vanished during the French Revolution and the rest were sold in the 19th century.

The Hope Diamond, now in the Smithsonian Museum in Washington, DC, was cut from the Royal French Blue Diamond.

The story of the Regent Diamond has been very well told in Julie Baumgold's The Diamond.

Germany - Germany wasn't a unified kingdom until the 1800s.  Thus, there are numerous royal families and many jewels still in existence.  We saw an exhibit of the treasures of Dresden (Saxony) on a 2006 trip to Versailles in France.  Photos were not permitted, but the items on display were amazing.  Details to follow. 

Hungary - The highly venerated thousand year old Crown of St. Stephen has probably been through more adventures than any other piece of jewelry on the planet.  Seized by the US Army in 1945, it was held in Ft Knox, along with the US Treasury, until 1978.

India - The emperors and rajas of India had fabulous jewels.  While many of those incredible stones and objects are now in other hands, there are many gorgeous pieces still under the control of the Indian people. 

I was overwhelmed by an exhibit of privately held Mogul jewels in 2002 in Houston (September 23, 2202 entry).

Ireland - Ireland was a land of many kings before England’s Henry II thought it would make a nice property for Prince John of Robin Hood fame.  While a few pieces of medieval Irish jewelry survive in museums and private collections, the case of the Irish “Crown Jewels” makes an interesting footnote to history.

Italy - Italy’s long history meant lots of crowns and other fabulous jewels – we saw a heart-stopping Etruscan laurel wreath crown of gold in a special 2004 Vatican exhibit in Shawnee,Oklahoma. (scroll down to the September 5 entry)

   Norway – The Norwegian crown jewels date from the 1800s.

Spain – With a number of kingdoms and several royal families succeeding one another – not to speak of the wealth of the Aztecs and Incas, one might expect more lavish jewels in Spain.

Thailand - The Siamese royals are close to the mines of Southeast Asia, and their jewels are consequently wonderful.

Turkey - The Gold Festival Throne is gold plated and covered with 957 peridots.  It's kept in Topkapi Palace along with other treasures.

United Kingdom - The queen’s regalia is kept in the Tower of London.  A tour of the historic Tower is a must-see on any trip to London.  They are breathtaking in number and beauty.  Photos are prohibited, but an article on the Tower is in progress.

When King John, who is better known for being forced to sign the Magna Carta as well as being the bad little brother of Richard the Lionheart, was on the throne, the crown jewels were lost in a swamp known as The Wash.

     Scotland - The Scots got to keep their crown jewels, the Honours of Scotland, when their King James VI became James I of England.
