Large Aragonite Star Cluster with Peach Crystal Growth

This Large Aragonite Star Cluster is an impressive mineral specimen featuring a dense arrangement of intergrown Aragonite crystals in warm peach, orange and soft honey-brown tones. The specimen has an especially attractive three-dimensional form, with several prominent crystal-rich sections creating a naturally sculptural appearance.

The crystals vary noticeably in size, from fine granular growth to larger, well-defined pseudohexagonal forms. Several larger crystals stand proud from the surface, providing excellent depth and contrast against the densely packed crystal matrix. Subtle variations in translucency allow light to pass through some of the crystals, revealing their internal structure and adding visual depth.

With its combination of larger crystals, intricate intergrowth and warm natural colouring, this specimen is an excellent choice for collectors looking for a substantial Moroccan Aragonite Star Cluster with plenty of character.

The Fascinating Crystal Structure of Aragonite

Aragonite is a calcium carbonate mineral that crystallises in the orthorhombic crystal system. Moroccan Aragonite is particularly sought after for its unusual twinning, which can produce crystals with an apparent hexagonal or pseudohexagonal form.

When many of these crystals grow together, they create the distinctive dense clusters for which Moroccan Aragonite is known. The combination of repeated twinning and varied crystal sizes produces remarkably complex surfaces, with individual crystals overlapping and interlocking to form intricate natural structures.

This specimen demonstrates that growth particularly well. Larger crystals are surrounded by numerous smaller crystals, creating a layered appearance that changes considerably depending on the viewing angle.

A Striking Moroccan Aragonite Display Specimen

The warm peach-orange colour palette gives this Aragonite cluster a soft, earthy character, while the larger crystals add definition and visual interest. Its irregular silhouette and varied crystal growth make it an engaging specimen to examine from different angles.

The contrast between translucent crystals and denser, more opaque areas further enhances its appearance. Rather than presenting a uniform surface, the specimen offers a variety of crystal textures and formations across its different faces.

Weighing 197 g, this Large Aragonite Star Cluster is a substantial and visually distinctive specimen, ideal for collectors who appreciate complex crystal growth and the natural beauty of Moroccan minerals.
