Vintage Gold Filled Heart Locket Engraved

Beautiful vintage yellow gold filled engraved heart locket pendant. Pretty flowers engraved on the front, flowing over a geometric grid, nice Art Deco look. Inside are two open compartments for photos or keepsakes (no plastic or glass covers), and the back is undecorated. Marked inside "Gold Filled" and "1/20 12KT". Color is a warm yellow like the first photo, more yellow than second photo looks. -- 3/4" x 3/4" excluding bale at top, and weighs 2 grams on my scale --Wonderful vintage condition with just a few tiny scratches as expected. Just lovely!
