The raw-looking internal crystal structure gives the piece an almost fossilised appearance while still maintaining a polished finish.\u003c\/p\u003e\n\u003cp\u003eKey Features\u003c\/p\u003e\n\u003cp\u003eMaterial: Septarian\u003c\/p\u003e\n\u003cp\u003eColour: Cream, honey, brown and black\u003c\/p\u003e\n\u003cp\u003eFinish: Polished with natural crystalline texture\u003c\/p\u003e\n\u003cp\u003eCarving: Skull\u003c\/p\u003e\n\u003cp\u003eUV Reaction: Calcite-rich areas fluoresce under UV light\u003c\/p\u003e\n\u003cp\u003eTransparency: Semi-translucent in some calcite-rich zones\u003c\/p\u003e\n\u003cp\u003eTexture: Crystalline and naturally fractured appearance\u003c\/p\u003e\n\u003cp\u003eFormation: Sedimentary concretion with mineral-filled fractures\u003c\/p\u003e\n\u003cp\u003eGeological \u0026amp; Scientific Notes\u003c\/p\u003e\n\u003cp\u003eSeptarian nodules formed millions of years ago when mudstone or clay-rich sediment began shrinking and cracking internally during dehydration. Mineral-rich fluids later filled these fractures, creating the dramatic natural vein systems seen today.\u003c\/p\u003e\n\u003cp\u003eThe creamy translucent zones in this carving are primarily calcite-rich material, while the darker brown patterning is commonly associated with aragonite and iron-rich sediment layers.\u003c\/p\u003e\n\u003cp\u003e�\u003c\/p\u003e\n\u003cp\u003eThe UV reactivity in this piece comes from the calcite-rich areas, which fluoresce under ultraviolet light due to trace elemental activators within the crystal structure.\u003c\/p\u003e\n\u003cp\u003eThe visible crystal texture throughout the skull gives the carving exceptional depth and geological character.\u003c\/p\u003e\n\u003cp\u003eWhy This Piece Stands Out\u003c\/p\u003e\n\u003cp\u003e• UV reactive calcite-rich zones\u003c\/p\u003e\n\u003cp\u003e• Natural fossil-like fracture patterns\u003c\/p\u003e\n\u003cp\u003e• Strong contrast between cream and dark brown banding\u003c\/p\u003e\n\u003cp\u003e• Visible crystalline internal texture\u003c\/p\u003e\n\u003cp\u003e• Highly unique geological formation patterning\u003c\/p\u003e\n\u003cp\u003eDimensions\u003c\/p\u003e\n\u003cp\u003e135 grams 5.7cm x 4cm \u003c\/p\u003e\n\u003cp\u003eCare\u003c\/p\u003e\n\u003cp\u003eHandle carefully due to the naturally crystalline structure of septarian material.\u003c\/p\u003e\n\u003cp\u003eClean gently with a soft cloth and avoid prolonged exposure to harsh chemicals or acidic cleaners.\u003c\/p\u003e","brand":"Crystal Ballerz","offers":[{"title":"Default Title","offer_id":53935247982933,"sku":null,"price":15.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1039\/9295\/1125\/files\/rn-image_picker_lib_temp_d5cdd191-10db-49fa-99ab-2f8966a3ae91.jpg?v=1778860680","url":"https:\/\/crystalballerz.co.uk\/products\/septarian-skull","provider":"Crystal Ballerz","version":"1.0","type":"link"}
