Story
Formed hundreds of millions of years ago from ancient evaporating salt lakes, this mineral specimen was hand-shaped into a glowing 'skyscraper' tower. Its silk-like fibers act like natural fiber-optic strands, transmitting light effortlessly along its length.
Maker / Origin
Likely most likely morocco.
Condition & Value
Appears to be in good pre-owned condition with typical natural internal fractures and minor edge nibbles along the soft top ridges. The paper retail label on the flat base is partially torn. Value is primarily determined by height, weight, and clarity.

Market Analysis
Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.
Value Drivers
- ▲ Strong maker attribution with credible period details
- ▲ Better-than-average condition for the category
- ▲ Broader demand rises when presentation and finish feel intact
Concerns
- ▼ Decorative-only demand limits the ceiling
- ▼ Surface wear or missing provenance can compress the range fast
- ▼ Regional sale lanes often underperform specialist venues
