This piece has that gorgeous icy, almost glass-like appearance Optical Calcite is known for, with layers of internal structure creating flashes of colour as the sphere is turned in the light.\n\u003c\/p\u003e\n\n\u003cp\u003e\nThroughout the sphere are intricate natural cleavage lines, veils and crystalline textures, giving it an almost frozen appearance. The real standout feature, however, is the collection of \u003cstrong\u003ebright internal rainbows\u003c\/strong\u003e. Depending on the angle, flashes of blue, pink, green, yellow and violet appear across the internal fractures, with some areas producing beautifully defined spectrum-like bands.\n\u003c\/p\u003e\n\n\u003cp\u003e\nOptical Calcite is particularly fascinating because of its interaction with light. Clear varieties of Calcite are known for \u003cstrong\u003edouble refraction\u003c\/strong\u003e, an optical phenomenon where light entering the crystal is split into two rays. Combined with the internal crystalline structures in this particular sphere, it makes for an incredibly interesting piece to turn and explore from different angles.\n\u003c\/p\u003e\n\n\u003cp\u003e\nSmall natural golden to ochre mineral markings are also visible in places, adding a subtle contrast against the otherwise icy-clear crystal. Every turn reveals something slightly different, from soft flashes of colour to larger concentrated rainbows hidden deeper within the sphere.\n\u003c\/p\u003e\n\n\u003ch3\u003eOptical Calcite\u003c\/h3\u003e\n\n\u003cp\u003e\nCalcite is traditionally associated with \u003cstrong\u003eclarity, cleansing, focus and personal growth\u003c\/strong\u003e. Clear and Optical Calcite varieties are particularly associated with mental clarity, perspective and helping to bring a sense of openness and understanding.\n\u003c\/p\u003e\n\n\u003cp\u003e\nRainbow-filled crystals are also often treasured symbolically for \u003cstrong\u003epositivity, hope and transformation\u003c\/strong\u003e, making this a lovely piece for both a crystal collection and a bright, uplifting display.\n\u003c\/p\u003e\n\n\u003ch3\u003eOften Associated With\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003eClarity\u003c\/li\u003e\n  \u003cli\u003eFocus\u003c\/li\u003e\n  \u003cli\u003ePositivity\u003c\/li\u003e\n  \u003cli\u003eTransformation\u003c\/li\u003e\n  \u003cli\u003ePersonal growth\u003c\/li\u003e\n  \u003cli\u003eSpiritual growth\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMineral:\u003c\/strong\u003e Optical Calcite\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eForm:\u003c\/strong\u003e Sphere\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Polished\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e Natural rainbows, internal cleavage lines \u0026amp; crystalline veils\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approx. 250g\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e Approx. 5.5cm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChakra:\u003c\/strong\u003e Crown \u0026amp; Third Eye\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIntention:\u003c\/strong\u003e Spiritual Growth\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Raven's Nest Crystals","offers":[{"title":"Default Title","offer_id":54620863332685,"sku":null,"price":26.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/5796\/8461\/files\/optical-calcite-sphere-rainbows-250g.png?v=1788117824","url":"https:\/\/www.ravensnestcrystals.co.uk\/products\/optical-calcite-sphere-with-rainbows-no-1","provider":"Raven's Nest Crystals","version":"1.0","type":"link"}
