1. **Gardening and Landscaping**: Volcanic rock is often used in gardening and landscape design because its porous structure aids in drainage and moisture retention, while also providing trace elements to plants.

2. **Building Material**: Due to its lightweight and fire-resistant properties, volcanic rock is commonly used in building materials, especially in fire bricks and insulation.

3. **Jewelry and Ornaments**: Volcanic rock is used to create jewelry and ornaments, particularly bracelets and necklaces. Its rough texture and natural colors add a raw beauty to the accessories.

4. **Massage and Healing**: Volcanic rock is often used in hot stone massage therapy because it absorbs and retains heat well, helping to relieve muscle tension and improve blood circulation.

5. **Aromatherapy Diffuser**: Because of its porous nature, volcanic rock is also used as an essential oil diffuser. When essential oils are applied, the volcanic rock slowly releases the scent, providing long-lasting aromatic effects.
