Vintage Brutalist Silver-Tone Square Pendant Necklace

This item is a vintage-style pendant necklace featuring an architectural, Brutalist-inspired square pendant attached to a textured silver-tone chain. The pendant measures approximately 1 to 1.5 inches across and is constructed from a non-precious base metal with a silver-colored plating. Its design is characterized by a grid-like or 'waffle' texture consisting of raised rectangular sections surrounding a central square motif, a common aesthetic in mid-century modernist costume jewelry from the 1960s and 1970s. The reverse side appears relatively flat with a similar geometric structure. The chain is an intricate double-link style, providing a sturdy and masculine weight to the piece. Regarding condition, the necklace exhibits significant signs of wear and age-related patina. There is visible tarnish and darkening in the recessed areas (oxidation), and the plating appears to be thinning or worn away in several high-point spots, revealing a darker base metal underneath. This type of wear is typical for base-metal costume jewelry of this era. While no specific maker’s mark is clearly legible in the current image, the construction style is reminiscent of commercial costume jewelry brands like Avon or Sarah Coventry from the late mid-century period. The craftsmanship is industrial and heavy, emphasizing form and texture over delicate detailing.
