Sidorenkite; Alluaiv, Lovozero, Kola, Russia; Min; unique piece
Sidorenkite from Alluaiv, Lovozero, Kola, Russia. Miniature specimen as unique piece for mineral collectors.
This miniature specimen with Sidorenkite originates from Alluaiv, part of the renowned Lovozero Massif on Russia’s Kola Peninsula – one of the world’s most important localities for rare alkali and earth element minerals. The featured piece shows Sidorenkite in matrix and is especially suited for systematic mineral collectors.
Sidorenkite is a rare aluminum-barium phosphate that often appears colorless to pale gray or beige and forms massive or fine-grained aggregates. Outside the Kola region, occurrences are extremely rare, which makes Alluaiv material particularly sought after in comprehensive collections focused on rare-earth element minerals.
Alluaiv belongs to the central alkaline complexes of Lovozero, an area famous for its exceptional mineralogical diversity and unique mineral parageneses including Eudialyte, Sodalite, Aegirine, and Loparite. Within this context, Sidorenkite is a geochemically specialized phase that illustrates the mineral-forming processes in nepheline syenitic environments.
This unique specimen is an excellent addition to any collection focused on rare phosphates, REE-bearing minerals, or the mineralogy of the Kola Peninsula. Offered as a one-of-a-kind collector’s piece.
