This black obsidian crystal is a great gift or a personal item to keep. You can place it in your room to create a calm and energetic atmosphere. It also makes a wonderful reminder when you keep the sentiment card with it. To maintain it, simply wipe it gently with a soft cloth every once in a while. Avoid dropping it as obsidian can break. Keep it away from harsh chemicals. You can carry it in the drawstring bag when you're on the go.
