The value of 1 gram of obsidian ranges from $0.10 to $5
Obsidian's price per gram varies based on quality, color, and processing. Raw, unpolished pieces cost as little as $0.10/gram, while high-grade polished specimens (e.g., rainbow or snowflake obsidian) can reach $5/gram. Jewelry-grade or rare varieties command premium prices, especially when cut into cabochons or beads.
Factors Affecting Obsidian's Price per Gram
- Type: Black obsidian is cheapest; rainbow, mahogany, or gold sheen varieties cost more.
- Processing: Raw chunks are affordable; tumbled, carved, or polished pieces increase value.
- Purity: Fewer inclusions or flaws raise the price, especially for lapidary use.
- Size: Larger single pieces (e.g., 100g+) may offer better per-gram rates than small fragments.
- Demand: Metaphysical markets (e.g., healing crystals) often inflate prices.
Price Comparison by Obsidian Type and Form
| Type/Form | Price per Gram | Typical Use |
|---|---|---|
| Raw black obsidian (unprocessed) | $0.10-$0.50 | Bulk purchases, lapidary rough |
| Tumbled black obsidian | $0.50-$2.00 | Jewelry, decorative stones |
| Rainbow/snowflake obsidian (polished) | $2.00-$5.00 | Collectibles, high-end jewelry |
| Carved obsidian (e.g., arrows, spheres) | $3.00-$10.00+ | Art pieces, metaphysical tools |
Where to Find the Best Prices
- Wholesale suppliers: Best for bulk raw obsidian (lowest per-gram cost).
- Online mineral markets: Competitive pricing for tumbled or polished pieces.
- Local gem shows: Opportunity to inspect quality before purchasing.
- Metaphysical stores: Higher prices but curated selections (e.g., "healing-grade").
How to Verify Obsidian's Value
- Check density: Real obsidian feels heavier than glass (specific gravity ~2.6).
- Examine edges: Natural obsidian has razor-sharp fractures; glass has smoother breaks.
- Look for inclusions: Bubbles or swirls (e.g., snowflake patterns) confirm authenticity.
- Test hardness: Scratches glass (Mohs 5-5.5) but is softer than quartz.
Cost-Saving Tips for Buyers
- Buy in bulk (e.g., 1kg lots) to reduce per-gram costs for raw material.
- Opt for "B-grade" pieces if minor flaws don't affect your use case.
- Avoid pre-drilled beads if you're cutting stones yourself.
- Compare prices across platforms-auction sites may offer rare varieties cheaper.
