Exceptional Moroccan Aragonite Star Cluster with Complex Crystal Growth

This Exceptional Aragonite Star Cluster is an impressive Moroccan mineral specimen with an extensive covering of intergrown Aragonite crystals in warm peach, orange, honey and subtle brown tones. The specimen is richly textured throughout, with numerous individual crystals ranging from fine granular growth to larger, more prominently developed forms.

Several areas display larger pseudohexagonal crystals with translucent edges and softly rounded faces, contrasting beautifully with densely packed smaller crystals. The variation in crystal size and orientation creates a highly complex surface, giving the specimen a distinctive sculptural quality when viewed from different angles.

The specimen is particularly striking for its substantial three-dimensional form and abundant crystal coverage. Its irregular natural shape, prominent crystal projections and contrasting areas of lighter and darker colour make it an excellent display piece for collectors who appreciate Aragonite specimens with strong visual presence.

The Fascinating Crystal Structure of Aragonite

Aragonite is a calcium carbonate mineral belonging to the orthorhombic crystal system. One of its most distinctive features is its tendency to form twinned crystals, which can create the characteristic pseudohexagonal appearances seen in many attractive specimens.

This cluster demonstrates that growth particularly well, with hundreds of crystals interlocking across its surface. Some areas are dominated by tightly packed smaller crystals, while others feature larger, more clearly defined forms that stand proud of the cluster.

The warm peach-orange colour palette is especially appealing, with translucent crystals allowing subtle variations in tone and depth to be appreciated. The natural contrast between crystal faces, edges and recessed areas adds considerable visual interest.

An Exceptional 402 g Aragonite Star Cluster

At 402 g, this specimen exceeds the 350 g threshold established for our Exceptional Aragonite Star Cluster category. Its substantial weight is complemented by an impressive crystal-covered surface and a strong three-dimensional presence.

The specimen has excellent display potential, with multiple faces offering different views of the intricate crystal growth. Larger crystals around the outer edges create a natural framework around the denser central growth, while the combination of translucent and more opaque crystals produces depth across the surface.

An exceptional Moroccan Aragonite Star Cluster with impressive size, abundant peach-orange crystal growth and remarkable three-dimensional character, this 402 g specimen is a standout choice for a serious mineral collection or display.
