In your case, the ruling planet Mercury has made you a very talented but also extremely volatile sign. You are very curious, playful, pleasant in company. You are a sign of duality that constantly strives to unite all these diverse aspects of personality into one whole.
You have a curious research mind in which ideas are constantly swarming. Overwhelmed by such a large number of ideas, you are often not able to set priorities and decide which ideas to implement and in what order, which can lead you to unenviable situations.
In your case, crystals can help you by slowing and directing you. For this purpose, get tourmaline, citrine, yellow calcite, jade, rutile quartz and carnelian.
Tourmaline - twins often don't even seem to understand themselves, so this is a great crystal that will give you mental clarity. It balances the left and right hemispheres of the brain, improves memory and transforms negative emotions into positive ones. It helps you to establish order and harmony in life.
Citrine - this crystal brings good mood, raises energy levels and gives the freshness that twins are constantly in need of. Citrine will clear your mind, make decisions easier and help you solve some dilemmas more easily. Known as the crystal of success, it will help you attract material prosperity and progress.
Yellow calcite - as you are forever in plans and ideas, yellow calcite will help you recognize quality opportunities and take advantage of them. It is a crystal of intellect, which will help you improve your organizational skills and achieve better concentration and memory. Since the twins are in constant motion, yellow calcite is good for you because it gives vitality, preserves health and brings a large amount of energy.
Jade - removes negativity and replaces it with calmness. This is a good crystal for you, as it will bring balance to your physical, emotional and intellectual body and help you relax and unwind sometimes.
Rutile quartz - this crystal is unique in its ability to connect you with the highest spiritual spheres, and thus to bring you fresh ideas, which is what the twins are constantly striving for.
Carnelian - this crystal will strengthen your curiosity and personal power. This is another crystal that will bring the twins what they love the most - enriching life with new knowledge and information.
