Fluorite and Quartz
An incredibly high quality example of "sugar fluorite", the luster and color are excellent. The fluorite cubes are well isolated on the surrounding quartz, and with their bright green color, they really pop into view. This quality and presentation is as good as it gets for this type. It glitters in every lighting environment! From Fujian, China. Acquired January 2023.

Fluorite is a highly prized mineral among collectors due to its remarkable range of colors, crystal clarity, and unique properties. This calcium fluoride mineral crystallizes in the isometric system, often forming well-defined cubes. Ill-defined cubes, and occasionally octahedral shapes. Its colors span a broad spectrum, including vivid purples, greens, blues, yellows, and colorless varieties, with some specimens showcasing multiple colors in striking bands or zones.
Many fluorite specimens are also fluorescent, glowing in shades of blue or purple under ultraviolet light, adding an extra layer of fascination. Found in hydrothermal veins, sedimentary deposits, and igneous rocks, notable sources of collectible fluorite include China, England, Mexico, and the United States. Its vibrant colors, distinct crystal forms, and fluorescent qualities make fluorite a standout addition to any mineral collection.
Quartz, the most common mineral on earth, is celebrated for its diverse forms, widespread availability, and captivating beauty. Composed of silicon dioxide (SiO₂), quartz crystallizes in the hexagonal system, often forming six-sided prisms terminated with pyramidal ends. This mineral is remarkably hard, ranking 7 on the Mohs hardness scale, which makes it durable and suitable for various uses. Quartz comes in an array of colors and varieties, including clear prismatic crystals, purple amethyst, smoky quartz, agates, jaspers, and much more.
Collectors are particularly drawn to quartz's ability to form large, well-defined crystals and fascinating inclusions, such as rutile needles or chlorite phantoms. Found in a multitude of geological environments, from igneous and metamorphic rocks to hydrothermal veins, notable quartz localities include Brazil, Madagascar, the United States, and Switzerland. The sheer variety and beauty of quartz, combined with its robust nature, make it an essential and versatile addition to any mineral enthusiast's collection.
