Larimar $4.00

Larimar is a rare blue variety of pectolite (NaCa₂Si₃O₈(OH)), a sodium calcium silicate mineral. Found only in the Dominican Republic, larimar displays a unique range of blue and turquoise hues caused by trace amounts of copper. These tumbled pieces have been polished to highlight their distinctive color and smooth texture. Features: Composition: Sodium calcium silicate hydroxide (pectolite) with trace copper contributing to its blue coloration. Appearance: Varies from light blue to deep turquoise with white streaks or patterns, polished to a glossy finish. Formation: Forms in volcanic cavities through the cooling of hydrothermal fluids rich in silica and other elements. Physical Properties: Moderate hardness (Mohs 4.5–5), relatively soft and requiring careful handling. Educational Value: Useful for studying mineral chemistry, volcanic rock formation, and trace element effects on mineral color. Tumbled larimar offers a rare glimpse into volcanic mineral formation with vibrant colors that reflect its unique geologic origins.
