Vintage Freemason Blue Stone Signet Ring

This is a vintage masonic signet ring, characterized by a prominent yellow-gold metal band and setting. The focal point of the piece is an oval-shaped, bezel-set blue stone, likely a synthetic spinel or glass, which features an inlaid or applied gold-tone Masonic Square and Compasses symbol with the letter G at its center. The shoulders of the ring are intricately cast with commemorative or lodge-specific relief work, a hallmark of mid-20th-century fraternal jewelry. While the specific gold karat is not visible due to image quality, such pieces were traditionally crafted in 10k or 14k gold. The item shows signs of moderate wear, including surface scratches on the metal and minor abrasions on the stone's facet edges, consistent with regular use. The overall construction follows a classic 'class ring' style common from the 1950s through the 1970s. The craftsmanship displays heavy casting with detailed symbolic iconography on the shanks, indicating a piece meant for daily wear and formal lodge functions. No maker's mark is visible in this view, but the design suggests American manufacture.
