The combination of brassy gold pyrite and contrasting dark mineral veins creates a bold, high-contrast appearance, enhanced by the mirror-like finish of the polished surfaces.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eUnlike typical quartz-based towers, this piece stands out for its dense metallic composition and weight, giving it a solid, substantial feel.

Its metallic lustre and pale brass-yellow colour are caused by its crystal structure, which reflects light efficiently across smooth surfaces.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe black inclusions visible within this piece are consistent with tourmaline, most likely the iron-rich variety known as schorl. Tourmaline forms under different chemical conditions than pyrite, meaning this specimen represents a multi-phase mineralisation process where two distinct minerals formed and became naturally intergrown.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe polished finish enhances the reflectivity of the pyrite while preserving internal structures, fractures, and inclusion zones—offering a clear view into the mineral’s formation history.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eCare Information\u003cbr\u003eAvoid prolonged exposure to moisture (pyrite can oxidise over time)\u003cbr\u003eStore in a dry environment\u003cbr\u003eDo not use harsh chemicals or acidic cleaners\u003cbr\u003eClean gently with a dry or slightly damp soft cloth\u003cbr\u003eAvoid dropping, as natural fractures may be present\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eWhy This Piece Stands Out\u003cbr\u003eHigh-contrast combination of metallic pyrite and black tourmaline\u003cbr\u003eDense, weighty feel compared to quartz-based pieces\u003cbr\u003eNaturally occurring inclusion pattern – no two pieces are the same\u003cbr\u003eStrong reflective surfaces that change appearance with light and angle\u003c\/p\u003e","brand":"Crystal Ballerz","offers":[{"title":"Default Title","offer_id":53777014030677,"sku":null,"price":26.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1039\/9295\/1125\/files\/rn-image_picker_lib_temp_2fc8114c-c23f-482f-b9ed-092fdeda2705.jpg?v=1777296059","url":"https:\/\/crystalballerz.co.uk\/products\/pyrite-polished-cylinder-tower-with-tourmaline-inclusions","provider":"Crystal Ballerz","version":"1.0","type":"link"}
