Victorian Drum Charm Mother of Pearl in Yellow Gold.  A very fine piece of Victorian craftsmanship is on display in this drum charm that is finished in 14 karat yellow gold. The delicate floral engraving continues all the way around the drum underneath a gold wire twisted and crisscrossed between buttons on the lip of the drum. The flat sections of the drum are made of mother-of-pearl and make this ornate drum charm look very realistic.
