Cluster of crystal quartz points - Lemurian quartz sample...

Collection specimen with well-formed primary crystals and remarkable transparency — This specimen represents a notable cluster of Quartz (Ialino), a macrocrystalline variety of silicon dioxide (SiO₂), characterized by its natural formation and crystal transparency. The crystals, developed according to the trigonal crystal system, display the typical striated prismatic faces and pyramidal terminations, indicating undisturbed growth inside a geode cavity or hydrothermal vein. The matrix, also quartz-rich but in a more massive and granular form, serves as the natural base for the aggregate. Visual analysis reveals primary crystals of significant size, accompanied by smaller secondary formations that enrich the piece's complexity. The transparency of many terminations is high, allowing observation of internal inclusions, predominantly liquid or two-phase, indicative of growth conditions. The color is typically colorless (Ialino), with some zones showing a slight milky opacity at the base of the larger crystals, fading to absolute clarity at the terminations. Provenance from Brazilian deposits is a distinctive mark for high-quality Quartz Ialino. Brazil is renowned for its extensive quartz formations, often arising from hydrothermal processes associated with igneous and metamorphic rocks. Slow crystallization in stable environments has allowed the development of specimens of this caliber, with a robust structure and notable crystal integrity. This piece offers an opportunity for geological study of quartz crystal growth dynamics. Aesthetically, the cluster is balanced, with a harmonious arrangement of crystals emerging from the matrix. The vitreous luster is exceptional, and the crystals interact with light in a spectacular way, creating internal and external reflections that enhance its three-dimensionality. The terminations are well preserved, with no evident signs of impact or alteration, although minor signs of growth or contact with surrounding rock are natural and attest to its geological authenticity. The piece is provided with a metallic support that emphasizes its verticality and facilitates display. The preservation state is excellent, with minimal signs of handling, demonstrating meticulous care in extraction and transport. A specimen of such weight and size, with crystals so well defined and transparent, is of considerable interest to collectors who appreciate the purity and morphological integrity of Quartz. Its presence in a collection can serve both as a striking aesthetic piece and as an educational reference for the study of quartz mineralogy. This cluster stands out for its significant mass and the crystal quality of its individual elements, placing it in a superior category compared to more common specimens. The combination of size, clarity, and the natural arrangement of the crystals makes it an ideal display piece capable of enriching any collection focused on aesthetic minerals and notable crystal formations. Its robustness and the intrinsic nature of quartz make it a durable investment with great intrinsic value."} }```>Oops JSON invalid due to extra backtick. Let's just provide proper JSON.
