Saturday's Gem - Serpentine

I have a special fondness for today’s gem (technically mineral) Serpentine.  Serpentine is a metamorphic rock that is very plentiful in California so much so that it is the actual State Mineral.  The reason why I like it so much is that it brings back fond memories of Terry’s and my first real rock-hounding expedition together. 

We drove at least 100 miles climbed to over 5,000 feet for an amazing rock-hounding experience.  Unfortunately since was very novice at that time we didn’t realize that the maps I bought and all the research I did on the site was not going to guarantee that we would actually find what we were looking for.  We wandered the mountains for several hours in 104 degree temperatures only picking up pretty specimens of Serpentine.  The site was supposed to be a treasure trove of abandoned mines with the possibility of garnet and other wonderful semiprecious gems and minerals, but Terry and I could only see green.

So we enjoyed our hike to the point of dehydration and decided that we better take a few of the specimens we found of Serpentine and call it a day.  The good thing was that we did not have any Serpentine in our collection since we just came from Wisconsin and so we still, to this day, have a large piece of our finds on display. 
A Couple of better specimens we found
Since Serpentine contains a mixture of magnetite, magnesite, talc along with other minerals such as asbestos the grades of the rock can vary quite a bit.  Some of the Serpentine we have found can only be used for display; it is much too soft and fragile to be used for anything else.  This type of Serpentine is called Crysotile (Fibrous.)  But some Serpentine can be a very durable beautiful green that will be wonderful for cabochons, beads, and carved collectibles, this is the Antigorite (scaly) Serpentine.  The color can vary from green to a yellowish green and even have a grey tone or be white.

Serpentine can be broke down into 3 more categories; Common (which is what we had found) Precious (which I wish we had found,) and Chrysotile Asbestos (which has industrial uses and not typically something I would want in my house.)  Precious Serpentine looks a little like Jade when it has been polished or made into jewelry.  But it should never be mistaken for Jade because there is a definite difference the look and in the value of the pieces.  I think every woman should have jewelry that is made from both, but that is just me.

This great ring was found on ArtFire at The Wild Tangent at http://www.artfire.com/ext/shop/product_view/thewildtangent/3719668
Metaphysically travelers used Serpentine as a stone for protection.  Often it was traders traveling from town to town or sailors that would wear Serpentine.  Native Americans wore it to protect them from any natural dangers while Roman’s used it to keep away hidden threats.  It has also been thought to be used in ancient cultures to help the dead with their travels from this world to the next.  It can also be used to protect the home from negative outsides forces such as intruders.  Overall Serpentine is the stone (metaphysically speaking) for most of us in this day and age; we are always on the move.

Saturday's Gem - Amethyst

Amethyst is part of the quartz family and is just like its relatives made of silica.  The quartz family is directly formed from cooling igneous magma that crystallizes during the low temperature stage.  It is one of the most common minerals and is found as a component in granite and sandstone along with many other common rocks.  But what makes Amethyst stand out in the quartz family is its pretty purple color.

Amethysts can vary in shades of purple from a very light lilac to a brilliant royal purple.  But when Amethyst is heated in extreme temperatures (such as over 500 degrees) it will become a yellow - brown color, Citrine, or even a greenish color.  It is often done now in labratories to create Citrine but it can also occur in nature where the Amethyst has been exposed to high heat from volcanic activity and the color changes naturally.
These beads are a wonderful example of the varience in colors that can occur.  You can purchase this lovely combination from KanduBeads at:  http://www.etsy.com/shop/KanduBeads?ref=seller_info
They are usually in the shape of a standard 6 sided crystal with some variations.  You may find amethyst that have "twinning" that means that it has two crystals forming from one base going out in two different directions.  They can also be found where there is a smaller "stem" like crystal with a larger crystal at the top, these are called Sceptre Quartz or Scepter since that is what they resemble.  Amethyst will often form in a cluster of crystals with a host rock holding it together at the base.   There are also Amethyst that have a Druzy Quartz appearance which are very pretty and make a great display let alone jewelry pieces.
This wonderful example of a Amethyst Crystal was found in Etsy Shop SolitaryMountain at http://www.etsy.com/shop/SolitaryMountain?ref=seller_info
I love this necklace and it shows a great example of a Druzy Amethyst.  It can be bought at Etsy shop ThirteenGems at http://www.etsy.com/shop/ThirteenGems?ref=seller_info
It is commonly found in many countries throughout the world but the large geodes that have become so popular among gem and mineral collectors are often found in Brazil.  I have been blessed with finding several pieces of Amethyst in California and it is relatively common to find them throughout the state and actually throughout the entire US.

Amethyst is February's Birthstone and has many important properties metaphysically.  Over the years it has been worn by priests to symbolize spiritual power and Romans to symbolize physical power.  Amethyst is also associated with easing guilt and fear.  It is also worn by travelers to protect them from sneak attacks and treachery.  Not only is the stone considered a protective stone but it is also is known to have powerful healing properties; it is reported ted to help ease headaches, insomnia and nightmares.  It is also reported to help the wearer be able to become more intuitive and in touch with the inner self.

Of course I have found some wonderful pieces of jewelry, specimens, and beads to share with you from Etsy.
