A gem of a find, this sterling silver Deco bar pin is adorned with diamante and channel-set clear and emerald green pastes and it is signed by CSS and Co.. I love the little sparkly bird shown in flight and want to believe it's a swallow. Swallows are the sentinels of spring in my country and I miss them so much here in upstate New York. Rich emerald green, flashes of crystal light from the clear pastes and sterling that complements them - so Deco indeed... The pin is 1 3/8" long by 9/16" wide (that is the height of the bird applique) and weighs 3.7 grams. It is signed with maker's initials "CSS Co" and "STERLING" both on the bar as well as on the pin closure and dates in the 1920s-40s. It is in excellent vintage condition with very good sparkle in the pastes, rich color in the emerald green ones, all of them in place, having the sweetest ever bird applique and no damage and no repairs noted.
