A bit too plain for jewelry, these lovely silk buttons are perfect for costuming & reenactorsThe 2 cards at the top have a subtle stripe, while the set at the bottom has a braided center. The braided buttons are in a hard setting, most likely vegetable ivory. All have padded backs to sew through. Because these buttons would be more permanently attach having been sewn on,  they were probably made for garments that weren't laundered as often such as coats & vests.
 
 
In the Victorian era, people enjoyed the use of symbolism in their everyday objects to provide additional meaning & transmit secret messages of love & friendship. There was entire "language of flowers," in which different floral arrangements conveyed certain feelings & messages. Even the placement & direction of a stamp on correspondence could convey a secret message of the heart.
One might expect anchors to represent the navy or military. In fact, the anchor was often paired in Victorian jewelry, accessories & buttons with a cross & heart. This trio represented faith hope & charity (or love), with the anchor meaning hope.
This card was made in Paris, France & the buttons still have their bright gold finish.
