Siderite Crystal on matrix - Height: 70 mm - Width: 42 mm- 62.78 g - (1)

A historically rare specimen with an exceptional provenance (Colombia), positioning it as a difficult-to-acquire specimen on the international market. The piece constitutes a paragenetic bimodal association of Siderite and Ankerite, both rhombohedral system carbonates. Siderite is the dominant matrix, exhibiting a distinctive lamellar and scaly morphology (known as 'dragon skin'). Crystals of Ankerite are arranged on this base. The aesthetic value is rooted in the compositional harmony of the set, enhanced by the striking chromatic contrast between the snow-white of the Ankerite and the predominant hue of the Siderite. An example of morphological balance and in an absolutely pristine condition.
