🔥 Glass Butte Psuedo-Fire Gold Sheen Obsidian Rough – Rare Oregon Cutter with Sunset Flash
This is a high-grade rough chunk of Gold Sheen Obsidian from the Glass Butte region of Oregon, showing a bold sunset-gold shimmer with hints of rainbow flash in certain angles. While not considered “true fire,” this psuedo-fire variant is one of the most dramatic sheen types from Glass Butte—visually evocative of sunset flames trapped in volcanic glass.
At 4 lbs 8 oz, this piece is large and blocky, perfect for slabbing into cabbing material, knapping into arrowheads or blades, or kept whole as a striking collector’s display. With old stock Glass Butte getting harder to source in large cutters, this is a beautiful and versatile example of an iconic Oregon obsidian.

📝 Description
Gold Sheen Obsidian is a naturally occurring volcanic glass prized for its shimmering metallic highlights caused by tiny gas bubbles or mineral inclusions (often magnetite) aligned during the cooling process. This particular specimen comes from Glass Butte, Oregon, one of the most iconic sources for sheen obsidian in North America.
Gold Sheen from this locality is known for its distinct reflective properties—ranging from subtle champagne tones to intense sunset gold flashes, and occasionally displaying rainbow overtones. It’s a versatile lapidary material that is commonly used in knapping, carving, or cabbing, and is highly collectible among obsidian enthusiasts.
While some pieces may contain natural pits or fractures, it generally works cleanly and rewards the cutter with striking, high-contrast finishes. With Glass Butte obsidian deposits becoming increasingly picked over, older and more visually striking pieces like this one are harder to come by.
