**Is Obsidian Expensive? Understanding the Pricing of This Volcanic Glass**

Obsidian pricing is far from straightforward, as its value fluctuates based on multiple interconnected factors rather than a fixed commodity rate like precious metals. Unlike oil or gold that trade on global markets, obsidian lacks standardized commercial pricing, making it challenging to assign a universal value.

**How Much Does Common Obsidian Actually Cost?**

Standard black obsidian typically trades at roughly $0.005 per gram when evaluated by weight and quality metrics. However, this baseline price serves merely as a reference point. The actual market value shifts considerably depending on whether you're purchasing raw specimens, polished pieces, or jewelry-grade stones.

**Factors That Influence Obsidian Valuation**

The pricing equation for obsidian incorporates several critical variables. Purity and clarity significantly impact the final cost—specimens with fewer inclusions command higher prices. Color variations also matter substantially; while black obsidian remains the most common form, unusual hues or patterns enhance value. Size is equally important, as larger stones without flaws become proportionally more valuable.

Perhaps most notably, regional market conditions play a decisive role. Obsidian sourced from specific geographical areas may carry premium pricing due to rarity, quality reputation, or accessibility factors unique to those locations.

**Premium Varieties Command Professional Assessment**

Specialty obsidian types, particularly fire obsidian with its distinctive appearance, defy simple per-gram pricing. These rare variants require professional appraisal to determine fair market value, as their scarcity and aesthetic appeal cannot be reduced to standardized metrics alone.

In essence, obsidian's expense level depends entirely on the specific specimen and your intended use—making informed evaluation essential before any purchase.
