The Gemini sign is the third sign of the zodiac and is known for its duality and complexity. Represented by two figures, the twins, the Gemini is a symbol of duality and understanding, as it’s often associated with the idea of understanding both sides of a situation. For many, it’s a sign of strength and resilience, as it’s thought to represent a person’s ability to adapt to different environments and situations. As such, it’s no surprise that the Gemini symbol is popular for tattoos.
