Locality: Sonora, MexicoShort wave UV botryoidal Chalcedony. Mixed quality. Hollow not guaranteed. Each geode is unique!*each pound requires 1.5 pounds of shipping space* The fluorescent or phosphorescent properties of UV geodes are primarily attributed to the presence of specific minerals or compounds. Examples include fluorite, calcite, willemite, and various forms of quartz. Color: The color of UV geodes can vary depending on the minerals present within the geode. When exposed to UV light, certain minerals fluoresce, emitting light of various colors. For example, fluorite might fluoresce blue or purple, while willemite can fluoresce green. The colors can be quite vibrant and striking under UV light. Hardness: The hardness of UV geodes can vary depending on the minerals present. For instance, quartz, a common mineral found in geodes, has a hardness of 7 on the Mohs scale, making it relatively durable. Other minerals found in geodes may have different hardness levels. Clarity: The clarity of UV geodes can also vary. Some geodes may contain clear or translucent crystals, allowing light to pass through them more easily, while others may have opaque or cloudy interiors. Clarity can affect the visual appeal and the intensity of fluorescence under UV light. Luster: The luster of UV geodes refers to the way light interacts with their surface. Some minerals may exhibit a vitreous (glassy) luster, while others may have a pearly or metallic luster. The luster can add to the overall visual appeal of the geode. Density: The density of UV geodes depends on the composition of minerals present within them. Different minerals have different densities, which can affect the overall weight and feel of the geode. Metaphysical Properties: In metaphysical belief systems, UV geodes are often associated with various spiritual or healing properties. These beliefs are not scientifically proven but are based on cultural and spiritual traditions. For example, some people believe that UV geodes promote positive energy, spiritual growth, and emotional healing. The specific metaphysical properties attributed to UV geodes may vary depending on cultural beliefs and individual interpretations. Photos have not been edited or altered, just taken in different daylight conditions to show the variation in color. Pieces are held in hand to help with scale and does not necessarily represent 1 pound. Specific pieces photographed may no longer be available.
