Elegant 8 mm black tourmaline stud earrings set in sterling silver. Perfect for any occasion. New Sterling Silver genuine black tourmaline stone pierced stud earrings. Brazilian Black Tourmaline is a powerful gemstone, known for its natural beauty and durability. It originates from the rich mines of Brazil, where it forms into striking black crystals. This tourmaline is often admired for its deep, glossy surface and robust structure. Black tourmaline (also known as schorl) is best known for its powerful energetic protection and deep grounding properties. It is widely used to absorb negative energies, shield against electromagnetic pollution, and anchor the root chakra to promote a strong sense of safety and stability. Not all '925' is created equal. My items are solid sterling silver, not silver-plated over brass or nickel. This piece is made of solid, high-quality sterling silver, designed to last a lifetime. I am a former jewelry artisan and silversmith/metalsmith/bench jeweler with deep technical knowledge of high-quality fabrication techniques and a background in identifying, sourcing, and setting natural gemstones.
