    In 2011 archeologists found under the Pyramid of the Sun in Teotihuacan (Mexico) a 2000-year-old green mask, made of serpentine. One way or another this fantastic news appeared on Twitter last year. And now quite a few people ask themselves… nice a mask… serpentine… what is ‘serpentine’?

    Don’t worry, I will explain and show you this stunning gemstone, that has so many possibilities for using it, that you might say #1 all-around gemstone.

    Let’s talk about that old mask first!

    The Pyramid of the Sun in Teotihuacan is built around 50 AD, but archeologists think that it is built on the ruins of another Pyramid or temple. And those builders are unknown, they vanished without a trace (until now) when the Aztecs took over.

    At the base, in a tunnel, deep under the ground, this stunning green mask, made of serpentine is found, together with 11 ceremonial clay pots dedicated to the rain god Tlaloc. And some animal bones, some pieces of obsidian, and three human statues were also made of serpentine.

    But the mask was most intriguing. It is very delicately and in detail carved so that it looks like a portrait. It is the first mask (and until now the only one) of this type that is found in a ritual context in Teotihuacan.

    Ans it is safe to say that even 2000 years ago people knew the gemstone serpentine and used it for carving statues and at least one mask.

    Mexico is not the only place…

    Although the green mask is rather old, it is not the oldest proof of using serpentine. In Ancient Times, the Sumerians, Assyrians, Persians, and Egyptians made seals of serpentine.

    When you polish this stone it gets a greasy and oily surface, which is ideal for seals. The wax or the clay could not stick to the surface and you could use the seal many times without cleaning it all the time.

    The cylindrical seal was used from about 3500 BC in Mesopotamia. And from that time on there is proof that people knew about the serpentine and its good features.

    People in those days loved its luster and it was used to make jewelry, statues, and household items. Not only because this gemstone was so beautiful, but also because it was rather soft (3-6 on Moh’s scale) and therefore easy to carve.

    The word goes that serpentine is protection against snakebites and other poisons and could act as a defense against evil spirits. Pendants made of this greenish stone were popular!.

    The Romans came up with the name

    Also, the Roman sorcerers were sure about the great feature of the gemstone of protecting against snake bites. And they called the serpentine ‘serpentines’ or ‘stone snake’. And all around the world civilizations thought the same and admired the gem for it.

    India, is the place to go

    The city of Bhera in Punjab (India) was famous for producing serpentine carvings, like mugs, statues, handles, and sword decorations. They imported it from Afghanistan and their name for it was ‘Sang-i-Yashm’, but the British called it ‘fake-jade’. And they have a point. Quite of few statues are sold as jade but actually are made of serpentine. The sellers have all kinds of nice names for it, like New Jade, Styrian Jade, or Suzhou Jade.

    All-round gemstone

    As stated serpentine is a rather soft gemstone and is perfect to make jewelry. That is if you stick to necklaces or earrings. For rings and bracelets, the gemstone is not strong enough and the jewelry can easily be damaged. But serpentine is used for much more than only jewelry.

    An architectural stone

    For thousands of years, serpentine is used for interior decoration, like wall tiles, columns, etc. The variety in colors, mostly green, the great patterns of the stone, the easy handling, and the great luster after polishing made this stone popular. It is softer than granite but harder than marble. In the first half of the 1900s, this material was very popular in the United States of America.

    Carved stone statues

    Serpentine and especially some varieties (the softer ones) are excellent carving materials. Ancient civilizations already found that out long ago. You can make sculptures from a few centimeters to several meters high and in all kinds of shapes.

    The soft stone and the possibility to polish them after carving give a beautiful result.

    Industrial stone

    Serpentine in general is a rather common stone and is abundantly found in many places. Especially the chrysotile variety is/was used as railway ballast, road surfaces, or building material. But the chrysotile serpentine contains asbestos, which can cause severe lung problems.

    Although asbestos is only a menace when you inhale the asbestos dust, at the moment a lot of countries have programs to get asbestos out of houses and the environment. Although the feature to stop a fire is perfect, people don’t want it anymore.

    That is also the reason that from the second half of the 1900s the popularity of serpentine as a building material diminished. Since 1965 this gemstone was the official stone of California (USA), but due to asbestos problems, the official status as state stone was discharged.

    What is serpentine actually?

    You may think that this gemstone is one single gem. But it is not! It is a group of 20 members or minerals, that are very hard to distinguish. They are created by a metamorphic process, that you see at low temperatures when heat and water come together and oxidize rocks.

    The minerals are made of tiny sheets of silicon and there are held loosely together. The weak connection between the sheets gives the gem that greasy or scaly look and slippery feel like a snakeskin.

    In the serpentine rock, you find small amounts of manganese, cobalt, nickel, and chromium and these elements are the cause of the different colors of the gemstone. The stone can be from apple green to black and every color in between, but the most common is olive green.

    The gem is opaque and you can see some veins in the stone. It is often mottled with light and dark-colored areas. The surface has an oily appearance and looks a bit soapy. The stone is most of the time fine-grained and compact, but sometimes more granular, platy, or fibrous.

    There are about 20 different varieties, but not all of them are suited for making jewelry. The best jewelry variety is antigorite and has no asbestos like the chrysotile variety.

    Other names are lizardite, atlantisite, greenstone, bowenite, and Willimansite. The general name ‘serpentine’ was given by Georgius Agricola in 1564 (not the Roman Emperor). He derived the name from the Latin word ‘serpens’, meaning snake, because of the snakeskin look of the gemstone.

    Where to find this gemstone?

    That is the easiest answer in this blog about serpentine. And the answer is in about every part of the world. From South Africa and Madagascar to Australia. From Peru to Austria, France, and the United Kingdom in Europe. But also in the United States of America and quite a few more places.

    20 Different types of serpentine

    Yes, there are about 20 variations of this gemstone. That is why I stated that this is more or less an all-around gem, also considering the different possibilities for using this stone. But don’t worry, I will only discuss the most important varieties for making jewelry with you.


    This variety is formed deep in the earth’s crust (at 60 kilometers or 37 miles or so) and is stable at the highest temperatures. Ideal for your jewelry. It contains 13% of water and scientist think that through antigorite water is transported to great depths.

    Antigonite has most of the time a light to darker green color, but can be yellowish, gray, brown, or black too. The hardness is 3.5-4 on Moh’s scale, so rather soft, and this type is not easy to cleave or cut.

    It is named after the first location it is found, Valle Antigorio between Switzerland and Italy. But is also found on every continent, even in Antarctica. When it is from Pakistan the color is yellowish-green and almost transparent.


    This is a variety of antigonite (can you still follow me?), which is harder (5.5 on Moh’s scale) and has a light to apple green color In the United States), mottled with cloudy white spots and somewhat darker veins. This variety is excellent for making jewelry.

    The Bowenite is named after G.T. Bowen who studied this gemstone, but it is also called ‘retinalite’ (yellow color) or ‘tangiwai’ in New Zealand. This Mr. Bowen thought that Bowenite was jade!!! So that you know what to look for in those countries.

    It is the state gemstone of Rhode Island in the United States and you can see it there more frequently in jeweler stores. In 1967 Mrs. Lady Bird Johnson received ‘Our Mineral Heritage Brooch’ with a Bowenite cabochon in it.

    In different countries the Bowenite has different colors: in Afghanistan it is green, the Bowenite from China is yellowish-green, in New Zealand dark bluish-green, and in South Africa, it is banded in green shades.



    In the United States, they have a local variety of the Antigonite, called Williamsite. It is oily green with black crystals of chromite or magnetite included. That magnetite can be so strong that you can move the stone with a magnet.

    It looks a bit like jade and is apple green with darker crystals of chromite and brucite. You find this variety in Maryland and Pennsylvania. The best quality is mined in Rock Springs, Maryland, and is deep green.

    Williamsite gemstone is called after L.W. Williams, who first found this gem and recognized it as a separate gemstone (variety)


    The most common faceted serpentine is the lizardite, another variety of antigonite. In different countries, you find different colors lizardite. In Kashmir and Scotland, they are gray or green, in the United Kingdom you will find various colors and all veined.

    Jade or serpentine or… jade?

    As mentioned above the serpentine is frequently mixed up with jade by accident or on purpose. Jade is more expensive so it makes it worthwhile to try and sell serpentine for jade.

    But… jadeite and nephrite both are heavier and tougher. They can stand blows better, even a blow with the diamond will not damage the real jade but certainly crack the serpentine.

    A lot of the serpentines on the market are treated with resin to make the gem stronger. Nothing wrong with that as long as you know. But they can also be dyed in green, or jade color and sold as jade. Or dyed in a completely different color. For instance, I have purple sugilite (as it is sold for), which is dyed serpentine. I noticed it because it was so much heavier than I expected.

    Another way of ‘fraud’ is using the serpentine together with jade in a so-called assembled stone. This means that the top is jade and the rest is another gemstone, most of the time much cheaper than the one on top. You can hardly check this, so buy your gemstones from known jewelers.

    How to take care of serpentine?

    Clean your beautiful gemstone with a soft brush or cloth, a mild detergent, and some hand-warm water. Just avoid steam or ultrasonic cleaning.

    Healing properties

    The serpentine has quite a few good features that could be to improve your health. No guarantees, but you can try all the same.

    It could resolve problems with diabetes and restore the right balance of magnesium and calcium in your body. It is said that it can cure heart and lung problems. This gem can relieve cramps and menstruation pains and help to renew cells. And… protects against parasite infections.
