Huge Black Rose Cube Fluorite 6 Lb Large Cabinet Specimen with Calcite and Blue Fluorite Inclusions Fluorescent Museum Quality AAAA Black Rose PakistanLocality: Pakistan
Weight: approx. 6 Lb. 7 oz. (2.738 Kg)
Measures: 8.5\'\' (126.90mm) x 7.5\'\' (63.45mm)x 4\'\' (50.76mm)AAAA Very RARE, High Grade Fluorescent Black Rose Cube Fluorite specimen with Calcite crystals inclusions, Barite and Blue Fluorite inclusions sourced from Pakistan. An outstanding example of a Large Cabinet Black Rose Cube Fluorite specimen that exhibits deep pure black color and perfectly formed cube clusters! The cubes have beautiful clean crisp faces and edges with a few etched cube faces as well. It displays phenomenally under LW UV lighting and also looks sensational in daylight! But despite of all of those attributes, the large size of this piece is impressive at over 6 Lbs. and 8.5\" on it\'s largest side!
The contrasting shapes and fluorescent colors of this crystal group, make this piece a very extraordinary three dimensional Black Rose specimen, and a must have collectable piece for any fluorescent collection. Black Rose Fluorite is a captivating mineral renowned for its deep and mysterious black cube crystal formation that invokes the mystique of a black rose. The combination of it\'s pure black coloring and deep red \"rose\" fluorescence, suggests the symbolism, that exudes the fascination and allure of this magical Fluorite. However, this stone\'s true wonder is ultimately revealed under Longwave Ultra Violet light (LW UV 365nm). This Black Rose Fluorite bursts into life remitting a vivid display of blue, purple and brilliant red luminescence.
Black Fluorite is one of the rarest colors to find and why it is so highly sought after.
Such a beautiful amazing piece and very collectable!Note: Be aware that being able to view fluorescent minerals requires an ultraviolet (UV) lamp. A LW UV 365nm was used for this specimen. A black light is not a UV light and in most cases fluorescent minerals will not fluoresce with a black light. What makes minerals fluorescent?Ultraviolet light is a form of electromagnetic radiation. Fluorescence occurs when electrons in certain atoms of a crystallized mineral absorb the radiated energy from a UV light (Photons). The incoming photons bump the electrons into higher energy states, and they respond to the ultraviolet light. The remaining light energy is out of balance and remitted and can be seen as a visible color. The reason for the fluorescent remitted colors is due to impurities in the mineral, or activators; which become part of the mineral’s chemistry by taking the place of atoms in the host mineral.
A majority of activators are atoms of certain metal elements that cause the resulting fluorescence in a mineral, Manganese is the most common activator. The level of fluorescence depends on the percentage of the impurities in relationship to the host atoms. Too much/little, results in low or no fluorescent response.Side Note: Fluorite, is also known as Fluorspar, is named for its fluorescence under ultraviolet (LW UV 365nm) and cathode-ray irradiation. Rare-earth elements, transition metal elements ( such as Chromium, Manganese, Iron, and Zinc) and alkaline elements (Sodium or Potassium) aka impurities, can often take the place of atoms in Fluorite basically occupying the crystal lattice structure of Fluorite. Since pure Fluorite is colorless, the existence and specific levels of these impurities determine the color of Fluorite in natural light, but also lead to the fluorescent color and phosphorescence it remits.
►►► Fluorite and surrounding rocks often contain radioactive elements. Therefore, Fluorite can be irradiated naturally before it is mined, not to say that it cannot be treated in a lab. Consequently, it would be unreasonable to suggest, assume or claim that a specimen is specifically treated in a lab, as apposed to natural irradiation, unless the lab made the claim.
