Cluster of Crystalline Quartz Points - Lemurian Quartz...

Collection specimen with well-formed primary crystals and notable transparency — This specimen represents a remarkable cluster of Milky Quartz (macrocrystalline variety of silicon dioxide, SiO₂), characterized by its natural formation and crystalline transparency. The crystals, developed according to the trigonal crystal system, show the typical striated prismatic faces and pyramidal terminations, indicating undisturbed growth inside a geode cavity or a hydrothermal vein. The matrix, also quartzitic but in a more massive and granular form, acts as a 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 apices is high, allowing observation of internal inclusions, predominantly liquid or two-phase, indicative of growth conditions. The color is typically colorless (milky white), with some areas 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 distinguishing mark for high-quality Milky Quartz. Brazil is renowned for its extensive quartz formations, often originating from hydrothermal processes associated with igneous and metamorphic rocks. Slow crystallization in stable environments has enabled 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 glassy 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 obvious signs of impact or alteration, although slight signs of growth or contact with surrounding rock are natural and attest to its geological authenticity. The piece comes with a metal support that enhances its verticality and facilitates display. The state of conservation 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 notable 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 crystalline quality of the individual elements, placing it in a superior category compared to common specimens. The combination of size, clarity, and natural crystal arrangement 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 lasting investment and of great intrinsic value.
