There has been a spread of royal houses across the continents, in the tumultuous years marked by two World Wars. It may well be that, in homes in the United States or abroad, a woman will be invited to a gathering at which a member of the nobility or of a royal family will be present. Whether the person is in actual power or dethroned by the vicissitudes of revolution, there is no need to wear more elaborate jewels than the occasion in itself calls for. A woman should always be herself, at her best; there is no need to seek better than that best for any nobleman. The effort would be undemocratic; the result would be overdone. Good taste, and the requirements of the particular party, formal or informal, should reign. Good taste does suggest one specific warning: under the circumstances, in deference to the noble guest, a woman should refrain from wearing a tiara, or any head jewel resembling a coronet. _Coronation_ A coronation, or a royal wedding—which usually includes the coronation of the one marrying into the reigning house—is a special function, growing less frequent in our strangely mixed times. The accession of Grace Kelly, however, to become Princess of Monaco, shows that these occasions may still spread their glamour wide. At such events, the type of diadem or coronet each person may wear is strictly defined in regulations that for centuries have been built up around the aristocracy in various lands. Manuals describe the ceremonial and the regalia in detail. An untitled woman privileged to be present will wear nothing but diamonds and precious and semiprecious stones; imitation jewelry is out of place. If she has a large diamond necklace, with pendants, there will be diamond earclips; if the necklace is a choker, the earclip may have pear-shaped diamond pendant or emerald or pearl drops. A beautiful diamond bracelet and ring will complete the regal costume. _A Queen’s Crown_ The monarch’s crown, and often his consort’s or his queen’s, has of course been handed down from the heads of those that ruled before. Occasionally there is a deviation from the tradition, as at the bridal coronation of Queen Geraldine of Albania. Geraldine was a Roman Catholic countess betrothed to a Mohammedan king. A royal crown usually bears a symbol of the monarch’s faith incorporated into its design; there are religious motifs in the ornamentation. In this case, naturally, such motifs and symbolism were not to be involved.
