3.3" Dark Purple, Amethyst Crystal Cluster with Calcite - Uruguay
This is a beautiful, 3.3" wide sparkling cluster of amethyst crystals with calcite, collected from the famous mines near Artigas, Uruguay. It contains many grape juice colored crystals that glimmer in the light. We import our material directly from the mines in Artigas, Uruguay and it is much darker, higher quality material than you normally see for sale.
About Uruguay Amethyst
Though Brazil produces a greater volume of amethyst, the material from the Artigas region of Uruguay is renowned for its exceptional depth of color and superb crystal quality. Uruguayan amethyst typically forms in dense basalt flows and develops into richly saturated, grape-purple crystals that are considered some of the finest in the world. Because we import our specimens directly from the mines, we’re able to offer outstanding prices on everything from dramatic geodes to premium clusters and collector-grade crystal formations.

About Calcite Crystals
Calcite crystals are a form of calcium carbonate (CaCO₃) known for their diverse shapes, transparency, and vibrant range of colors. They typically form in rhombohedral, scalenohedral, or prismatic shapes, often with well-defined, sharp edges and glossy surfaces. Calcite crystals are often translucent or transparent, sometimes displaying a double refraction effect where objects viewed through the crystal appear doubled. They can appear in various colors—white, clear, yellow, pink, blue, green, and orange—depending on impurities or trace minerals.
A notable characteristic of calcite is its reaction with weak acids like vinegar, which causes it to effervesce, or fizz, as it releases carbon dioxide. This property makes calcite crystals a key tool in geological identification and studies. Calcite forms in many environments, from sedimentary rocks like limestone and marble to hydrothermal veins.
