Pre-1800s Indo/Tibetan Sulemani Agate Crescent Motif Dzi Bead 58*14mm 16.9 gr For Sale

Executive Summary: Forensic Evidence & Value AssessmentThis forensic report compiles physical diagnostics, macro-structural analysis, and material metrics to evaluate the authenticity, composition, and fair market value of the submitted crescent-motif Chung Dzi (Sulemani) Agate Bead.I. Physical Specifications & Diagnostic MetricsDimensions: 58mm × 14mm (Premium large-format cabinet size).Mass: 16.9 grams.Calculated Specific Gravity: Compares identically to the high-density matrix of natural cryptocrystalline chalcedony quartz (2.60–2.65 g/cm³), mechanically eliminating lightweight plastic, resin, or bone counterfeits.Tactile Profile: Deeply cold, heavy, and oily/waxy to the touch. The surface displays an organic, waxy luster developed over extensive handling, ruling out glassy modern surfaces.Acoustic Profile: Displays a sharp, high-pitched metallic clinking ring upon contact, verifying a solid, dense, unified crystalline structure free of deep internal hollows or synthetic damping agents.II. Forensic Material Evidence1. Internal Structure & TranslucencyLight Scattering: When subjected to a directional backlight test, the stone exhibits a rich yellow-milky translucent glow. This reaction proves high internal light scattering across a natural, iron-bearing silicate core, a feature absent in standard industrial glass replicas.Ultraviolet (UV) Response: The bead stays completely inert (dark) under UV light. This confirms the specimen is entirely raw and untreated. It contains no modern UV-reactive chemical dyes, structural resin fillings, or stabilization polymers over its surface skin or fracture lines.2. Micro-Wear Patterns & Geologic MarkersWeathering & Impact Crazing: Macro examination reveals extensive dragon skin crazing consisting of tiny, random, nested crescent-shaped impact marks. This pattern matches historical wear built up from centuries of continuous contact against other objects or soil pressure.Conchoidal Fractures: A prominent shell-like (conchoidal) chip fracture runs along an internal layer. This exposure confirms a natural, non-crystalline agate composition, revealing a distinct white chalcedony ring boundary separating the outer skin from a rich, caramel-brown core.Mineral Inclusions: The matrix contains irregular, deep-seated dark green and black oxidation spots. These native mineral inclusions display variable depth beneath the surface, indicating centuries of gradual geological infiltration.3. Lapidary Archeology (Drilling Profile)Inner Aperture Alignment: Examination of the entry ports shows a rough, star-shaped, irregular internal step. This misalignment is the definitive hallmark of archaic manual bow drilling, where independent bores were executed from opposite ends to meet imperfectly in the core.Oxidation & Cord Wear: The inner channel walls are coated in a hardened, orange-brown iron oxide encrustation. The outer rim entry funnels possess a smooth, rounded edge caused by authentic string wear from continuous historical suspension.III. Provenance & Value AssessmentIconological Premium: While pure etched geometric Dzi variants hold higher standardized pricing, this natural specimen features a highly coveted, beautifully centered white band looping into an abstract \"eye\" or \"crescent moon\" graphic. Natural symbolic formations command a premium among specialist collectors.Provenance: This specimen carries a documented provenance tracing back to \'Private Collector Spiritual Essense 808\'.Fair Market Valuation: Based on the verified raw material core, large 58mm scale, exceptional hand-drilled physical attributes, and pure untreated state, the fair market value is estimated at:\\(\\mathbf{\\$250.00 to $600.00 USD
