Universe Charm Sterling Silver | Astronomy Jewelry | Solar System Jewelry | Made in USA

Our sterling silver alloy uses copper in the 7.5% composition — never the nickel that many overseas producers substitute to cut costs. That distinction matters for the estimated 10-20% of the population with nickel sensitivity. After casting, each piece is hand-polished through progressive compounds to a clean, reflective surface. A sterling silver jump ring comes attached and ready for wear.

The flat-cast design renders concentric orbital rings around a central sun, evoking the elegant diagrams of Copernicus and Kepler that first mapped our place in the cosmos. It is an understated piece — recognizable to anyone who looks closely, but subtle enough for everyday wear.

Makes a meaningful gift for astronomy enthusiasts, science teachers, planetarium volunteers, astrophysics students, or anyone who has ever stayed up too late staring at the Milky Way. Works beautifully as a pendant on a chain or as a focal charm on a bracelet.
