The American National Retail Jewelers Association assigned garnet to January in 1912 when they created the modern birthstone list. Historical associations between garnet and winter months date back to ancient trade routes, where the stone represented warmth and safe travel.
Garnet measures 6.5 to 7.5 on the Mohs scale, depending on variety. This hardness level withstands normal daily activities. Remove garnet jewelry during heavy physical work or exposure to harsh chemicals to preserve the stone's surface.
All necklaces use .925 sterling silver, an alloy containing 92.5% pure silver. This standard provides durability while maintaining the white metal appearance that complements garnet's red tones.
