Golden Peacock Obsidian Identification Guide
How to identify golden peacock obsidian by its gold-dominant multicolor iridescent sheen on black glass, conchoidal fracture, and the rainbow obsidian it overlaps with.

What Golden Peacock Obsidian Looks Like
Golden peacock obsidian is iridescent volcanic glass — black at rest but flashing gold, green, blue, and purple peacock-like iridescence when tilted. The sheen, dominated by gold tones, arises from light scattering off aligned nanometer-scale inclusions (commonly magnetite or hedenbergite nanorods) in flow layers. The base is black, glassy, opaque to translucent on edges.
Visual cues:
- Black glass base with multicolor iridescence weighted toward gold
- Sheen appears as concentric bands or sheets that shift with angle
- Bright vitreous luster, smooth surface
- Conchoidal fracture, sharp edges, no crystals
Step-by-Step Field ID Checklist
- Tilt under a point light. Look for the moving gold-plus-peacock color bands; the colors travel as you rotate.
- Confirm glass base. Black volcanic glass, wet glassy luster.
- Test hardness. Obsidian is Mohs 5–5.5; quartz scratches it.
- Check fracture. Conchoidal, shell-shaped curves with razor edges.
- Weigh it. SG ~2.4, light in hand.
Key Diagnostic Tests
- Iridescence: multicolor with gold dominance, directional and concentric.
- Hardness: ~5–5.5.
- Fracture: conchoidal, no cleavage.
- Specific gravity: ~2.4.
- Inclusions: aligned nanoparticle layers cause the sheen (visible cause under strong magnification).
Common Look-Alikes and How to Tell Them Apart
- Rainbow obsidian: the same mechanism and largely the same material; 'golden peacock' is a marketing emphasis on gold-rich iridescence. Rainbow obsidian may show stronger greens/purples.
- Gold sheen obsidian: shows a single golden sheet, not the multicolor peacock spread.
- Labradorite/spectrolite: crystalline feldspar with two cleavage directions and a blocky habit; obsidian is glass with conchoidal fracture and no cleavage.
- Goldstone (glass): dense pinpoint sparkle, no directional color bands, has bubbles.
- Bornite (peacock ore): a metallic sulfide that tarnishes iridescent but is opaque, heavy, and gives a streak — not glassy.
Where Golden Peacock Obsidian Is Found
Iridescent (sheen and rainbow) obsidian comes chiefly from Mexico's Jalisco obsidian flows, the main commercial source, with similar material from the western United States and other rhyolitic volcanic regions. It forms where silica-rich lava cools rapidly with trace nanoinclusions aligned during flow.
Frequently asked questions
How can you tell if golden peacock obsidian is real?
Genuine golden peacock obsidian is black volcanic glass that flashes gold-dominant multicolor iridescence when tilted, breaks with conchoidal fractures, has a hardness near 5–5.5, and feels light. The colors move and appear in concentric bands rather than as static glitter.
What is the difference between golden peacock obsidian and rainbow obsidian?
They are essentially the same material with different color emphasis. Golden peacock obsidian shows iridescence weighted toward gold (with green, blue, and purple accents), while rainbow obsidian may display a fuller, more balanced spectrum of bands.
Golden peacock vs gold sheen obsidian — how do I tell them apart?
Gold sheen obsidian shows a single sheet of golden reflection. Golden peacock obsidian shows multiple iridescent colors, dominated by gold, in concentric moving bands. More than one color means peacock.
Why does golden peacock obsidian show colors?
Aligned nanometer-scale mineral inclusions trapped in the lava's flow layers scatter and interfere with light, producing structural iridescence that shifts as you change the viewing angle.
Is golden peacock obsidian the same as peacock ore?
No. Peacock ore is bornite, a metallic copper-iron sulfide that tarnishes to iridescent blues and purples. Golden peacock obsidian is glassy volcanic glass; bornite is opaque, heavy, and leaves a grayish-black streak.
