Goldfieldite typically forms in hydrothermal veins and is often associated with other telluride minerals, such as sylvanite and calaverite. It appears as small, metallic, and prismatic crystals, frequently occurring in aggregates. The color of goldfieldite varies, ranging from light gray or silver to a brassy yellow hue.
Goldfieldite is highly valued for its gold and silver content, making it an important ore of these precious metals. Its composition includes varying percentages of gold and silver, with tellurium as a key component. This mineral is commonly sought after by collectors and prospectors due to its rarity and economic significance.
Despite its value, goldfieldite has limited industrial applications. It is primarily used in the production of jewelry, as an investment commodity, and in the manufacturing of certain electronic components.
