Natural Aragonite Sphere · 6.7 cm · Blue Aragonite

This natural Blue Aragonite sphere measures approximately 67 mm in diameter and displays an attractive range of sky-blue to deeper ocean-blue tones, contrasted by naturally occurring brown mineral patterning.

Aragonite is a naturally occurring calcium carbonate mineral (CaCO₃) and is one of the principal crystalline polymorphs of calcium carbonate. Unlike Calcite, Aragonite crystallises in the orthorhombic crystal system, giving it a distinct mineralogical identity despite sharing the same basic chemical composition.

The sphere shows a visually appealing combination of soft blue, medium blue and deeper blue areas, with irregular brown accents and natural structural variation distributed throughout the material. These contrasting zones give the specimen depth and create a highly individual appearance from different viewing angles.

Blue Aragonite may display cloudy structures, radial or fibrous growth textures, botryoidal-looking formations and irregular mineral zoning. In a polished sphere, these natural internal structures become particularly visible as sweeping tonal transitions and patterned areas across the curved surface.

At approximately 6.7 cm in diameter, this specimen has substantial visual presence and is particularly suitable for a mineral collection, cabinet display or decorative natural stone presentation. The larger spherical form allows the colour variation and geological structures to be appreciated continuously around the entire specimen.

The surface has been carefully polished to enhance the stone’s natural vitreous to resinous luster while retaining visible internal structures, colour zoning and mineral patterning.

Because Aragonite is relatively soft compared with Quartz and many faceted gemstones, the sphere should be handled with reasonable care. Natural surface-reaching features, fine fissures or small structural variations may occur and are consistent with the mineral’s natural formation.

Each natural Aragonite specimen develops differently, meaning that no two spheres show exactly the same balance of blue coloration, brown patterning or internal structures.

With its substantial 67 mm size, distinctive blue colour range and naturally contrasting brown mineral patterning, this Blue Aragonite sphere offers strong collector and decorative appeal. Its polished finish reveals the mineral’s internal textures and colour zoning clearly, making it an individual natural specimen with considerable visual presence.
