I am surrounded… Designed in collaboration with Maum Market, the Korean Trigram Ring represents the four trigrams in the Korean flag. The trigrams represent movement and harmony as fundamental principles. The four corners of the Korean flag represents one of the four classical elements - 건 geon (air), 곤 gon (earth), 감 gam (water), 리 ri (fire). Respectively, these elements symbolize justice, vitality, wisdom, and fruition. The Korean Trigram is a representation of the power of community and the movement of Maum to build partnerships across Asian-owned small businesses. Maum Market is a monthly marketplace that features a mindful curation of local Asian artists, creatives, and entrepreneurs. 925 Sterling Silver. Polished Finish. Nickel free. Handcrafted in Korea Sterling silver naturally tarnishes when exposed to salty air, chlorine, sulfur, humidity, perspiration, cosmetics, household bleach and other strong chemicals. To remove any tarnish, we recommend routinely wiping your sterling silver jewelry with the polishing cloth included. Regular wear of LOUPN sterling silver jewelry can also help prevent tarnishing as the oils in your skin help keep Silver from oxidizing faster. Remove heavy tarnish with warm water, mild soap and a clean, soft cotton or flannel cloth, a special sterling silver cleaning cloth or a very soft-bristle brush like a baby toothbrush. Silver polish or dip-style cleaning solutions are NOT recommended. When not in use, please store the design in the provided pouch with the anti-tarnish tab.
