A captivating combination of brilliant turquoise-blue, delicate translucent crystals, and golden metallic contrasts, this Selenite on Shattuckite with Marcasite specimen offers an incredible variety of colors and textures.
Intricate, glass-like selenite crystals form sparkling clusters and delicate layered formations across the vibrant blue mineralization. Creamy yellow accents and dark metallic-looking marcasite add depth, while small crystal-lined pockets create beautiful details to discover from every angle.
With its dramatic color palette and fascinating mineral association, this is an eye-catching addition to any mineral collection.
Dimensions: 3 × 2.5 × 1.5 inches
Weight: 168 grams
Locality: Ojuela Mine, Mapimí, Durango, Mexico
Selenite: Mental clarity, energetic cleansing, peace, and spiritual awareness.
Shattuckite: Communication, intuition, truth, and emotional understanding.
Marcasite: Grounding, focus, confidence, and personal transformation.
Together, these minerals are believed to encourage clear communication, balanced energy, and a deeper connection to intuition.
A mineral named after the moon! Selenite takes its name from Selene, the Greek goddess of the moon, inspired by its luminous, appearance. Despite its name, selenite contains no significant selenium; it is a crystalline variety of gypsum.
A mine with a bridge in the sky! Ojuela Mine is famous not only for its extraordinary minerals but also for its historic suspension bridge, which once carried mining materials across a dramatic canyon. Today, the bridge remains one of the area's most recognizable landmarks.
The secret behind the blue: Shattuckite is a copper-bearing mineral that develops its striking coloration through its chemical composition. It typically forms during the alteration of copper deposits, when mineral-rich fluids interact with existing copper minerals.
Marcasite's surprising twin: Marcasite and pyrite have exactly the same chemical formula, FeS₂, but their atoms are arranged differently. This makes them polymorphs, proving that the same ingredients can create two distinctly different minerals!
Care: This specimen contains delicate crystal formations. Keep it dry, avoid prolonged humidity, and handle gently. Marcasite is especially vulnerable to oxidation in humid conditions.
