The provided source material, unfortunately, consists of a single document – a legal filing related to Event Rentals, Inc. – and contains no information pertaining to gemstones, birthstones, or the properties of tourmaline. Therefore, a 2000-word article on tourmaline, adhering to the strict guidelines of utilizing only the provided sources, is impossible.
However, I can summarize the content of the provided source and briefly outline what a comprehensive article on tourmaline would cover, based on established gemological knowledge (which, per the prompt’s restrictions, cannot be directly incorporated into the article itself).
The document [1] is a legal filing from a bankruptcy case, specifically concerning Event Rentals, Inc. It details a claim for rent owed at a property located at 10669 Birthstone Dr, El Paso, TX. The filing includes information about the debtor, the creditor, the amount claimed, and supporting documentation related to the lease agreement. The document provides no information about the origin of the street name "Birthstone Dr" or any connection to gemstones. It is a standard legal document and offers no insights into gemology, history, or cultural significance.
What a Comprehensive Article on Tourmaline Would Cover (Based on External Knowledge – Not Included in the Article):
A detailed article on tourmaline, adhering to the prompt’s requirements if sufficient source material were available, would likely cover the following areas:
History and Lore: Tourmaline’s history is relatively recent compared to other gemstones. It was brought to Europe in the 18th century by Dutch traders from Ceylon (Sri Lanka). Before that, it was known in Brazil, but not widely recognized. The name “tourmaline” comes from the Sinhalese word toramalli, meaning “finger stone,” likely referencing the stone’s tendency to attract dust and small particles. Historically, tourmaline was believed to possess protective powers and was used to ward off negative energy. Different colors of tourmaline have accumulated unique lore over time.
Geological Formation and Sources: Tourmaline is a complex borosilicate mineral formed in granitic magmas and metamorphic rocks. It crystallizes in elongated, prismatic crystals. Major sources include Brazil, Afghanistan, Africa (Nigeria, Mozambique, Tanzania), Sri Lanka, and the United States (Maine and California). The geological conditions required for tourmaline formation result in a wide variety of chemical compositions, leading to its diverse color range.
Gemological Properties: Tourmaline boasts a remarkable range of colors, making it highly prized by collectors and jewelers. Its chemical formula is complex, varying depending on the elements present. It typically ranges from 7 to 7.5 on the Mohs hardness scale. Key properties include:
- Chemical Formula: Complex borosilicate (e.g., (Na,Ca)(Al,Li,Mg)3(Al,Fe,Mn)6(BO3)3(Si6O18)(OH)4)
- Crystal System: Trigonal
- Hardness: 7-7.5 (Mohs scale)
- Refractive Index: 1.614 – 1.666
- Specific Gravity: 3.06 – 3.10
- Cleavage: Indistinct basal cleavage
- Luster: Vitreous
Types of Tourmaline: Numerous varieties of tourmaline exist, categorized by color and chemical composition:
- Rubellite: Red to pink tourmaline, colored by manganese.
- Indicolite: Blue tourmaline, colored by iron.
- Verdelite: Green tourmaline, colored by iron and chromium.
- Schorl: Black tourmaline, colored by iron.
- Paraíba Tourmaline: Neon blue to green tourmaline, colored by copper, and highly valued.
- Watermelon Tourmaline: Displays pink and green zones.
Symbolism and Metaphysical Beliefs: Tourmaline is often associated with protection, healing, and emotional balance. Different colors are believed to have specific properties. For example, pink tourmaline is linked to love and compassion, while black tourmaline is thought to ground energy and protect against negativity.
Care and Cleaning: Tourmaline is relatively durable but can be susceptible to damage from heat and harsh chemicals. Cleaning should be done with warm, soapy water and a soft brush. Ultrasonic cleaners should be avoided.
Conclusion:
Due to the limitations imposed by the sole source document, a comprehensive article on tourmaline cannot be produced. The provided material is entirely unrelated to the subject matter and offers no factual basis for such an article. The above outline represents the content a detailed article would contain, based on established gemological knowledge, but it cannot be included within the constraints of the prompt.
