Sordavalite is a rare mineral that is found in the Turkestan Range in Kazakhstan. The word "Sordavalite" is pronounced as /sɔrdəvəlaɪt/ with the emphasis on the second syllable. The pronunciation of the word reflects its spelling, with each letter representing a specific sound. The first syllable "sor" is pronounced like the word "sore." The second syllable has a distinct "d" sound followed by a short "a" sound. The final syllable contains a long "i" sound and the letter "t" is pronounced clearly.
Sordavalite is a fairly rare mineral that belongs to the phosphate mineral group. It is typically classified as a complex hydrated sodium iron aluminum phosphate with the chemical formula NaV5Al3(PO4)10·26H2O. The mineral was first discovered in the 19th century in the Ilmen Mountains of Russia.
Sordavalite is known for its distinct deep blue to blue-green color, which can be attributed to its composition and crystal structure. It typically occurs as small prismatic crystals or as fibrous aggregates within granite pegmatites. The mineral is often associated with other phosphates and rare-earth elements.
In terms of properties, sordavalite has a Mohs hardness of around 4-5, indicating that it is relatively soft. Its specific gravity varies between 2.43 and 2.47, which suggests that it is moderately dense. Sordavalite also exhibits perfect cleavage and has a vitreous or almost resinous luster.
Due to its rarity and attractive blue color, sordavalite has been sought after by mineral collectors and lapidaries. However, its use in jewelry is limited due to its softness and lack of abundance. The mineral's beautiful coloring, coupled with its intricate crystal formations, also make it a subject of interest for researchers and scientists studying the mineralogy of phosphate minerals.
Overall, sordavalite is an intriguing and visually appealing mineral that holds significance within the scientific and mineral collecting communities.
