This is a traditional Chinese Feng Shui decorative amulet in the form of an octagonal copper Bagua mirror with a central Taiji (Yin-Yang) symbol. Crafted from solid brass/copper with a polished golden finish, it measures approximately 22.5 cm across diagonally and weighs 495g, indicating substantial heft and quality. The front features eight trigrams (Bagua) surrounding the reflective Taiji center, each inscribed with corresponding Chinese characters (Qian, Dui, Li, Zhen, Xun, Kan, Gen, Kun). The reverse side (shown inset) displays intricate Taoist deity or talismanic engravings, enhancing its spiritual protective function. Designed for hanging on doors, walls, or above entrances to deflect negative energy (Sha Qi) and promote harmony and balance according to classical Feng Shui principles. Its heavy gauge (0.4cm thick) ensures durability and authenticity as a ceremonial object rather than a lightweight novelty. Ideal for home, office, or temple decoration; not wearable jewelry but a symbolic architectural accessory. While culturally significant, it functions primarily as a spiritual decor item—not a fashion accessory—hence categorized under accessories > brooches for display-purpose ornamental objects.
