Measuring approximately 1.5–2 inches, it’s an approachable size for hands‑on learning, display, or building a rock collection. Its visible banding makes it especially useful for geology students, educators, and anyone curious about how minerals form over time through changing conditions.\u003c\/p\u003e\n\u003cp\u003eWhy you'll love this:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNaturally occurring calcite with visible banded patterns\u003c\/li\u003e\n\u003cli\u003eMeasures approximately 1.5–2 inches, making it easy to handle and display\u003c\/li\u003e\n\u003cli\u003eSmooth surfaces highlight mineral layering and structure\u003c\/li\u003e\n\u003cli\u003eDurable specimen suitable for classroom use, study, or collections\u003c\/li\u003e\n\u003cli\u003eHelpful for exploring mineral formation, color variation, and Earth science concepts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA simple, engaging way to explore geological processes through real mineral structure.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Howard","offers":[{"title":"Default Title","offer_id":50115641442497,"sku":"R699","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0074\/0638\/7247\/files\/BandedCalciteR699Howard_159b65f6-e3db-4ea5-a7d3-758c530f307a.png?v=1775142666","url":"https:\/\/store.smm.org\/products\/banded-calcite-6-99","provider":"The Science Museum of Minnesota","version":"1.0","type":"link"}
