Santa Rosa Tourmaline

Santa Rosa Tourmaline (Available 53+ grams) Santa Rosa tourmaline, primarily found in Brazil, is known for its vibrant green and teal colors, often displaying a unique color zoning transition from teal at the base to a darker emerald green at the top. These gem-quality crystals are typically transparent with minor internal fractures and exhibit a glassy luster with striations parallel to their length. Some specimens also display a chatoyancy effect, and can feature complex, multi-tiered terminations. Here’s a more detailed breakdown: Color: The most common colors are rich green and teal, often with a distinct color zoning effect where the base is a lighter teal and the top transitions to a darker, emerald green. Some specimens also exhibit pink or orangish-pink hues at the base. Clarity: Generally transparent, with some specimens exhibiting minor internal fracture inclusions. Luster: Santa Rosa tourmaline is known for its glassy luster. Texture: The crystals often display striations parallel to their length, and some may have a chatoyancy effect. Termination: Many specimens have a complex, multi-tiered termination, sometimes appearing as a mass of fibrous filaments, rather than a smooth termination, according to iRocks.com. Rarity: While green tourmaline is relatively common, high-quality specimens with intense color saturation and exceptional clarity, like those from Santa Rosa, are rare and highly sought after by collectors, notes Adastra Jewelry. Location: Primarily found in the Santa Rosa mine, Itambacuri, Minas Gerais, Brazil. Historical Significance: Some specimens were mined in the 1970s and 1980s, with some of the finest examples coming from this era. Due to the rarity of new discoveries, specimens from this locality are increasingly valuable.
