Is serpentine a toxic rock?
No, serpentine is not a toxic rock. The misconception is that chrysotile asbestos (a fibrous mineral) is one of three minerals that make up serpentine.

Does serpentinite contain asbestos?
Serpentinite often contains many veins, some of which may be filled with the fibrous mineral chrysotile (a form of asbestos). Chrysotile is a serpentine mineral in which the silica sheets are rolled into tiny tubes to form hollow fibers. Loose asbestos fibers cause lung disease if you inhale them.

Are There Synthetic Serpentines?
Since serpentines (especially chrysotile) have many practical applications, scientists have synthesized this material in laboratory settings for research purposes.
Do Serpentines Receive Artificial Treatments?
Serpentines may receive treatments, such as impregnation with resin (to improve stability) and dye (to improve color). Green dyes may enhance their “jade-like” appearance, but serpentines may also receive dyes for colors beyond their natural range, such as orange and purple. These dyed serpentines may simulate other gemstones besides jade, such as sugilites.
Is it Dangerous to Wear Serpentine Jewelry?
However, the normal wear and handling of finished chrysotile pieces will pose no health risks. Non-fibrous chrysolite gems and objects won’t release breathable, hazardous particles. Other finished serpentine varieties are also safe to wear.
Where did Bowenite come from?
Italy, and Lizard, Cornwall, England. Bowenite is after G. T Bowen, who studied material from Rhode Island (though he misidentified the material as nephrite). Williamsite is named after L. W. Williams, who first found it. Serpentine forms due to the alteration of basic and ultrabasic rocks.

What are the physical properties of serpentine?
Once cut and shaped, serpentine gemstones are predominantly light and dark green patterned stones that are slippery to the touch. Impurities in the stones can produce attractive veins and marbled patterns. They are often cut with a high dome shape to accentuate these patterns.
Where is Serpentine Found?
Serpentine is most often found at points where oceanic plates converge with the mantle , as this produces the hydrothermal conditions most conducive to creating serpentine minerals. Although they are not commonly found on the Earth's surface, there are substantial portions of the planet that have serpentine hidden underneath.
How are serpentine gemstones made?
Serpentine gemstones are derived from minerals created from a process of serpentinization — a metamorphic process that occurs at low temperatures combining heat and water to oxidize ultramafic rocks, creating the telltale fibrous or plate-like patterns that look like snake scales.

Is serpentine a mineral?
Serpentine is well known to the world's mineralogists and gemologists, but is much less familiar to the general public. The marbled look of this green stone makes it ideal as an ornamental material, and it has been carved into a wide array of decorative objects throughout history. Although serpentine has a similar appearance to jade, it is a different, unrelated series of minerals.
Why is serpentine removed from the state rock?
A bill introduced by California State Senator Gloria Romero in February 2009, the language of which was completely gutted and then amended in April of this year, would “remove serpentine as the state rock and lithologic emblem and would leave the state rock unspecified.” Why introduce a bill to the state assembly devoted to removing the state rock? The primary reason, as stated in the bill, is because “serpentine contains the deadly mineral chyrsotile asbestos, a known carcinogen, exposure to which increases the risk of cancer mesothelioma.” Supporters of the bill include cancer awareness groups and other groups representing those dealing with mesothelioma.

In that spirit, I think some basic geologic facts are in order: • Firstly, “serpentine” refers to a group of minerals, not a rock. The term “serpentinite” is the proper term for the rock that is mostly made up of one or more of the serpentine group minerals.
Is serpentinite poisonous to humans?
As one blogger put it, the only way a piece of serpentinite might be harmful is if someone hurled a piece at you. To reiterate, one must inhale the powdered version into their lungs for it to be harmful. The wording of the bill is such that it’s not surprising there is some confusion and misunderstanding. Some of the mainstream reporting about this bill has failed to communicate that exposure to the rock serpentinite is distinct from exposure to the powdered form of a component mineral that might be in the rock. This is an important distinction.
Composition
- In this formula, X will be one of the following metals: magnesium, iron, nickel, aluminum, zinc, or manganese; and, Y will be silicon, aluminum, or iron. The appropriate generalized formula is thus
Geology
- Chrysotile, antigorite, and lizardite are three of the primary serpentine minerals. There are many other serpentine minerals, most of which are rare. During hydrothermal metamorphism, olivine and pyroxene minerals are transformed into or are replaced by serpentine minerals. Some of the metamorphic rocks produced here are composed almost entirely of serpentine minerals. These …
Properties
- Serpentine group minerals have similar physical properties and form by similar processes. They often occur as fine-grained admixtures and can be difficult to distinguish within a rock. Geologists usually call these materials \"serpentine\" rather than more specific names to simplify communication. Serpentine has some durability concerns. It has a hardness that ranges from 3 …
Formation
- Serpentine minerals form where peridotite, dunite, and other ultramafic rocks undergo hydrothermal metamorphism. Ultramafic rocks are rare at Earth's surface but are abundant at the oceanic moho, the boundary between the base of the oceanic crust and the upper mantle. They are metamorphosed at convergent plate boundaries where an oceanic plate is pushed down int…
Significance
- These areas of exposed oceanic plate are known as ophiolites. They are often the source of valuable minerals that might include magnetite, chromite, chrysoprase, jade, and serpentine.
Appearance
- The most obvious physical properties of serpentine are its green color, patterned appearance, and slippery feel. These remind the observer of a snake and that is where the name \"serpentine\" was derived. Serpentine is also known for its translucent diaphaneity, waxy luster, ease of being cut into shapes, and its ability to accept a polish. These properties make it a popular gemstone, arch…
Use
- Serpentine has been used as an architectural stone for thousands of years. It is available in a wide variety of green and greenish colors, often has an attractive pattern, works easily, and polishes to a nice luster. It has a Mohs hardness of 3 to 6 which is softer than granite, and usually harder than most marble. This low hardness limits its appropriate use to surfaces that will not receive abrasi…
Nomenclature
- In the dimension stone trade, serpentine is often sold as \"marble.\" It might also be described as \"serpentine marble\" or given a trade name that does not include the word \"serpentine.\" This is a tradition of the industry and is usually not a misidentification of the material. This practice severely irritates some geologists. :-)
Management
- After they were discovered to be connected to lung and other cancers, their use was mostly discontinued, and a campaign to remove them from many of their uses began. Removal programs have been ongoing for decades and are still being done today. It has been one of the most costly removal programs in history.
Collections
- Serpentine sculptures range in size from under one centimeter to several meters in height. Bowls, vases, desk sets, clock bases, animals, fruit, flowers, legendary figures, deities, busts, and statues are all common objects made by artists working with serpentine.
