This is the Cameo Tiara, a delicate and lovely miniature crown of pearls and feminine cameos which is owned by…King Carl Gustaf of Sweden! However the Swedish king doesn’t wear it, but rather lends it out to women in his family when they are being married. The cameos were carved separately and gathered into a crown in the first decade of the nineteenth century when cameos were all the rage. The crown was a gift from Napoleon to Josephine (or at least it is assumed that that is how she obtained it). Since the fall of the First French Empire, the little crown passed through surprisingly few hands. Orders of Splendor, a blog dedicated to such things describes its history succinctly:
Josephine left it to her daughter Princess Eugénie, who left it to her nephew Prince Eugén. Eugen loaned it to his niece by marriage, Crown Princess Margaret, and eventually gave it to Princess Sibylla of Saxe-Coburg and Gotha when she married Prince Gustaf Adolf in 1932. Sibylla lent it to her sister-in-law, the future Queen Ingrid of Denmark, for a costume ball and ultimately left it to her son, King Carl Gustaf.
The pretty crown seems ideally suited to weddings because of the central cameo—but that cameo is itself the subject of minor controversy. To me it appears to be Venus teasing her son Cupid by holding some cherished object just out of his reach (archery equipment maybe…or a girdle or even a crown). Others. However, see it as a Psyche and Cupid—although frankly I enjoy Psyche and Cupid art when the two are more evenly matched in age (and when Psyche is not unwisely tormenting her spouse). Maybe the question adds charm and interest to the piece.
Whatever the case it is a beautiful little crown. I just wish we could see what is on the other four cameos on the back! The next time a Swedish princess invites me to her wedding I will be sure to ask (in a polite and cautious manner of course, the last thing I need is to be stabbed by some rich beefy Scandinavian nobleman).
