The field library / Collection 01
Obsidian.
A volcanic moment, held still.
Obsidian is natural volcanic glass, commonly dark and strongly reflective. It offers a useful contrast to crystalline minerals: its geological story is one of rapid cooling rather than a large, ordered crystal growing into space.

01 / The expanded collection card
A name.
A mineral identity.
Obsidian is not a quartz crystal and has no single mineral formula. It is a glassy volcanic material whose composition and inclusions can vary.
NPS · Volcanic glass ↗- Material identity
- Natural glass
- Composition
- Silica-rich glass; variable
- Mohs hardness
- About 5–5.5
- Luster
- Glassy
Hardness describes scratch resistance, not resistance to breaking. These values follow the cited material references; reported ranges can vary between publications. Inclusions, mixtures and treatments can affect an individual piece.
02 / A moment of observation
Look a little closer.
Curved fractures
Fresh broken surfaces can have curved, shell-like outlines and very sharp edges.
Glass-like reflection
A polished surface may reflect strongly without containing a crystal's internal structure.
Patterns and inclusions
Bands or visible inclusions can occur, but a trade name alone is not a verified geological description.
Observation builds familiarity; it does not replace identification. Avoid scratch, acid or destructive tests on a collection piece.
03 / The geological story
Made by the earth.
Recorded with care.
How it forms
Silica-rich lava can cool so rapidly that much of it remains glass instead of forming visible crystals. Geological context is part of distinguishing a natural occurrence from manufactured glass.
NPS · Volcanic glass ↗An example to explore
Yellowstone, United States / geological context
The National Park Service describes Obsidian Cliff at Yellowstone and the significance of its volcanic glass. This is an example of a natural occurrence, not a claim about a product's source.
NPS · Obsidian at Yellowstone ↗What does this tell me about my stone?
A recorded occurrence gives geological context. Your Stone Parade piece needs its own batch information before a locality can be stated. Keep an original specimen label or documented supplier record with the collection card.
04 / From a material to an object
Ways to wear.
Ways to keep.
A pause in pictures
From earth to everyday.
A visual look at obsidian and jewelry forms inspired by its palette.

Jewelry & practical use
Polished beads, cabochons and carvings can be comfortable objects to wear or handle. Raw edges deserve different treatment: a broken glass surface can be much sharper than a rounded bead.
One useful distinction
A raw stone describes a finish. A mineral specimen describes an object kept for its features or locality. The terms can overlap, and a specimen does not have to be large.
In Stone Parade, the mineral selection may be a raw stone or a collector-sized mineral specimen.
05 / A little thoughtful care
Keep the beauty.
Keep the story.
Choose a method for the whole object: stone, matrix, cord, metal and any treatment. A care shortcut that suits one material can damage another.
Protect against chipping
Do not drop the piece or knock a thin edge against a hard surface.
Handle rough carefully
Keep sharp raw fragments away from places where hands brush past them.
Use a soft cloth
A polished surface is easily marked by contact with harder stones.
Before you collect / treatments, names & provenance +
Ask for the material identity and documented provenance. Dark or brightly colored glass is not automatically natural obsidian.
Personal symbolism is individual. The crystal-culture section explores symbolism separately from the mineral science and care references.
Another way to connect / Crystal culture
Meaning, energy
& personal ritual.
Alongside its geological story, obsidian can become a personal symbol. Explore healing traditions and chakra language as cultural beliefs and reflection prompts.
Symbolic associations, not established medical effects. Crystals have not been shown to treat illness or balance a measurable human energy field.

Healing, energy & the sources behind this section +
In contemporary crystal practice, “healing” and “energy” often describe beliefs about subtle energies, intention and personal experience. Such language is different from measured mineral properties or demonstrated treatment effects. This section offers optional symbolism and does not replace healthcare.
The museum sources document beliefs and objects, not clinical efficacy. In a 2025 controlled study of rose quartz and a matched placebo, anxiety changes did not show a crystal-specific benefit beyond placebo. That study does not test every stone or every practice.
Our tags are transparent editorial reflection pairings, informed by the contemporary color-based approach; these sources do not validate every stone-to-chakra correspondence. Mineral science references remain in the chapter’s own research section.
06 / Follow the research
Curiosity, with
something to follow.
Care references & editorial notes +
Care suggestions combine the specific sources above with GIA’s jewelry care guidance. Recommendations are deliberately conservative when a piece’s treatment or matrix is unknown. IMA-CNMNC and RRUFF provide further nomenclature and analytical research; listing them does not imply laboratory testing of a Stone Parade item. Some older Handbook entries preserve historical names; chapter-specific modern nomenclature references take precedence where noted.
Reference properties and locality examples reviewed October 30, 2026. Photographs show particular objects. Jewelry style studies show possibilities, not an inventory promise.
