Aquamarine

This striking multi-mineral pegmatite specimen from Brazil brings together colour-zoned Beryl, displaying icy blue Aquamarine and soft pink Morganite, with deep green Tourmaline and shimmering Mica. The contrasting crystal forms create a beautifully layered composition, from the broad hexagonal faces of the Beryl to the slender, vertically striated Tourmaline crystals growing alongside it.

A substantial pale matrix anchors the formation, adorned with reflective, silvery to bronze-toned Mica plates that catch the light and provide a luminous backdrop to the coloured gemstones. Weighing 1,874g and measuring 16cm x 13cm x 10.5cm, this cabinet specimen has the presence to become a captivating focal point within a mineral collection.

At the centre, the prominent Beryl formation reveals a delicate transition between cool blue Aquamarine and pastel pink to peach Morganite. These distinct colour zones invite a closer look, while the deep green Tourmaline provides a striking contrast to the softer tones. Beneath them, the Mica’s layered, book-like structures add texture and shifting reflections, rewarding attention from different angles.

This association offers a fascinating glimpse into the changing conditions within a crystallising pegmatite pocket. Aquamarine’s blue colouring is generally associated with iron, while Morganite’s pink to peach tones are associated with manganese. Their occurrence within one Beryl crystal reflects changes in its growth environment. The neighbouring Tourmaline adds another dimension to the specimen’s formation, developing within the boron-rich conditions characteristic of many gem-bearing pegmatites.

A compelling piece for a collector drawn to unusual mineral associations, pastel gemstone colours and contrasting crystal structures, this substantial specimen makes a beautiful anchor for a thoughtfully arranged display.
