Staknala green cap tourmaline on albite matrix Mineral Collection - Height: 36 mm - Width: 34 mm- 33 g - (1)

Green cap tourmaline on albite matrix represents a fascinating specimen combining two distinct minerals. Tourmaline is a crystalline boron silicate mineral composed of several elements such as aluminum, iron, magnesium, sodium, lithium, or potassium. The green variety, often termed verdelite, is prized for its vibrant emerald to apple-green hues, which result from traces of chromium or vanadium. Albite, the matrix in this specimen, is a common feldspar mineral that forms as white to grey crystalline masses, providing a contrasting backdrop that highlights the rich green cap of the tourmaline crystal. Such associations are often found in pegmatitic environments where slow cooling allows well-formed crystals to develop. Collectors value crystals on matrix because they preserve the natural context of mineral formation, enhancing aesthetic and scientific significance. This specimen, measuring 36 mm in height and 34 mm in width with a weight of 33 grams, exemplifies a fine example from mineral collections, showcasing natural crystal growth and coloration that appeals to both enthusiasts and geologists alike.
