Rubaya Tourmalines

Rubaya Tourmalines (1 Mozambique) Rubaya tourmalines, particularly those from the Rubaya Pegmatite District in North Kivu, DR Congo, are known for their exceptional quality, including vibrant colors, clarity, and complex terminations. These tourmalines are considered to be some of the finest available on the market. They often exhibit a teal color that can fade into blue and green tones. Rubaya tourmalines are primarily elbaite, with a modest liddicoatite component and Fe and Mn as main chromophores, according to Laurs et al. (2017). Here’s a more detailed look at their properties: Color: Rubaya tourmalines are known for their stunning and diverse colors, including deep greens, blues, and rare pinks and reds. Clarity: They often exhibit good clarity, making them desirable for jewelry and collections. Crystal Morphology: The tourmalines from this region are known for their sharp and complex terminations, which are a hallmark of quality. Structure: Rubaya tourmalines can have perfectly preserved terminations, such as the antilogous pole with well-defined trigonal pyramids. Locality: Rubaya is a specific pegmatite district within the Bahunde, Masisi Territory of North Kivu, DR Congo. Rarity: While production has declined, Rubaya tourmalines of this quality are increasingly difficult to find, making them sought-after specimens. Other minerals: They can be found in association with other minerals like quartz, albite, lepidolite, microlite, and cassiterite. Mining: The area is known for its tourmaline gem rough, and while many crystals are damaged during extraction, high-quality specimens are still found. Illicit Trade: The region is also known for the illicit export of tourmaline gem rough, often through Uganda, from the capital Goma. Rubellite: Some Rubaya tourmalines exhibit a subtle red or pink hue, making them rubellites.
