Shoyeido created the Jewel Series to evoke the spirits of five precious stones, each a symbol of humanity’s greatest inner qualities: Diamond, for power. Ruby, for strength. Emerald, for awareness. Sapphire, for devotion. Amethyst, for balance. Each fragrance is blended from only the finest aromatic woods, herbs, roots, resins and spices. Each bundle contains forty 5.25″ sticks that burn for 30 minutes each.
