This stunning 1 year AA Medallion is a Black Color Tri-Plate meaning that it has the clear epoxy dome (very glass like) and Gold and Silver Plating. BUT what really sets this sobriety chip apart are the Clear Sparkly Diamond Like Swarovski Crystals which are installed by persons in recovery. The crystal color changes in various lighting. The back of the coin has the Serenity Prayer in gold and a single Swarovski Crystal in the center of the coin. Great gift to celebrate anniversaries in Alcoholics Anonymous.
