Vintage lot 2 pr silver earrings, styles contemporary & tribal

1st pair marked sterling, signed S.J. Length 1.5 inches, perfect condition, simply beautiful with five inscribed black lines and a pleasing well proportioned shape. 2nd pair tribal in feel, unmarked, laser cut with a dark etched background. 1.25 inches in diameter, convex on the front like a shield. There are minor areas of wear that show a copper color layer under the silver finish. Appears plated, polishes with a jeweler's cloth just like tarnished silver. Despite flaws, these earrings are striking. Both from my personal collection, purchased new during 80s to 90s. Questions, comments, and offers welcome.
