Among these, bi-color tourmaline is one of the most popular and highly demanded varieties. Its rarity makes it more expensive compared to most other tourmaline colors, second only to the coveted Paraiba tourmaline. Bi-color tourmaline is also commonly referred to as \"watermelon tourmaline\" due to its distinctive and striking appearance.\u003c\/p\u003e\n\u003cp\u003eTourmaline is a complex borosilicate mineral that contains a combination of elements such as aluminum, iron, magnesium, lithium, or potassium. Its chemical composition can vary widely, resulting in an extraordinary range of colors. Tourmaline crystallizes in the trigonal system and typically forms in elongated, prismatic crystals with vertical striations. It has a hardness of 7–7.5 on the Mohs scale, making it a durable gemstone.\u003c\/p\u003e\n\u003ch3\u003eAssociations and Properties\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eGeological Associations\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTourmaline is commonly found in granite pegmatites, metamorphic rocks, and hydrothermal veins.\u003c\/p\u003e\n\u003cp\u003eIt is often associated with quartz, feldspar, lepidolite, and beryl in pegmatite deposits.\u003c\/p\u003e\n\u003cp\u003eNotable sources include Brazil, Madagascar, Afghanistan, and Nigeria.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCultural and Mystical Associations\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTourmaline is believed to possess protective and grounding properties.\u003c\/p\u003e\n\u003cp\u003eWatermelon tourmaline (bi-color variety) is often associated with emotional healing and balance.\u003c\/p\u003e\n\u003cp\u003eIt is a popular stone in crystal healing practices for promoting creativity and harmony.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptical Properties\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTourmaline exhibits pleochroism, where it displays different colors when viewed from different angles.\u003c\/p\u003e\n\u003cp\u003eSome specimens show chatoyancy (cat's-eye effect) or even asterism (star effect) when cut and polished properly.\u003c\/p\u003e","brand":"Folkmarketgems","offers":[{"title":"Default Title","offer_id":51750061736258,"sku":null,"price":10800.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/5376\/6978\/files\/79B17136-8E92-4AC0-87F8-587C34EBDEAB.jpg?v=1767076730","url":"https:\/\/www.bullvendors19.com\/products\/200-carats-graded-quality-tourmaline-raw-crystals-for-faceting","provider":"Bull Vendors 19","version":"1.0","type":"link"}
