This premium individual specimen stands out due to its textbook, masterclass morphology. When backlit, the stone undergoes a breathtaking transformation, revealing an absolute masterclass of internal structures. Right in the center of its symmetrical, radial "fan-like" sculpturing lies a perfectly formed, translucent gas bubble depression that acts as a natural lens, focusing the light. The deeply etched ridges and miniature channels elegantly radiate outward from this central point, showcasing the extreme rotational forces and fluid dynamics during its atmospheric flight 15 million years ago. Key Geological & Visual Features: Exceptional Translucency: Displays the highly prized, vibrant South Bohemian bottle-green color (vibrant Chlum green) with outstanding clarity across the entire surface. Central Bubble Feature: A magnificent, prominent central gas bubble depression that forms the exact origin point of the radial fan-like surface textures. Weight: 5.90 grams (premium investment-grade weight class over 5g). Edge Detail: The outer rims are highly detailed, showcasing a wild, naturally etched and jagged "saw-tooth" texture that contrasts beautifully with the bright, glowing interior. An elite-tier display specimen for high-end mineral cabinets, discerning collectors, or exclusive investment portfolios. Condition: Pristine, natural raw specimen with unbroken structural integrity
