With the last post of this month on Gemstone Each Month Series (GEMS) – January, we would be posting about how to care for Garnet Jewelry. Here are a few tips which can help you keep your jewelry last longer.

Garnet Necklace

  • Clean garnet jewelry with a soft, dry cloth only.
  • Avoid exposing your garnets to harsh chemicals.
  • Garnet scratches more easily than other gemstones, so be careful with it. Wrap each piece of garnet jewelry in a separate cloth to keep it from touching other pieces.
  • Avoid wearing or keeping your jewelry in places with extreme temperatures.
  • Store your garnet jewelry in a dry place, preferably away from sunlight.

So those were a few tips on how to care for Garnet Jewelry, they can be used for other gemstone jewelry as well. We would be announcing GEMS February soon, do email us your suggestions to info@jewelstruck.com.

Here we go with another post on Garnets, with our Gemstone Each Month Series (GEMS) for January. We would be discussing about metaphysical and healing properties of Garnets.  If you would like to share anything on Garnets, send it asap to info@jewelstruck.com – only two days left for this month of Garnet to end :-)

Metaphysical Properties

  • Color – Garnets species are found in many colors including red, orange, yellow, green, blue, purple, brown, black, pink and colorless. The rarest of these is the blue garnet, discovered in the late 1990s in Bekily, Madagascar. It is also found in parts of the United States, Russia and Turkey. It changes color from blue-green in the daylight to purple in incandescent light, as a result of the relatively high amounts of vanadium. There are some beautiful orange garnets. A green tsavorite garnet is a very rare and high-priced stone. The dazzling beauty of garnets is responsible for their widespread use as gemstones.
  • Luster – Garnet species’s light transmission properties can range from the gemstone-quality transparent specimens to the opaque varieties used for industrial purposes as abrasives. The mineral’s luster is categorized as vitreous (glass-like) or resinous (amber-like)
  • Structure – Garnets are most often found in the dodecahedral crystal habit, but are also commonly found in the trapezohedron habit. They crystallize in the cubic system, having three axes that are all of equal length and perpendicular to each other. Garnets do not show cleavage, so when they fracture under stress, sharp irregular pieces are formed.
  • Hardness – Because the chemical composition of garnet varies, the atomic bonds in some species are stronger than in others. As a result, this mineral group shows a range of hardness on the Mohs Scale of about 6.5 to 7.5. The harder species, like almandine, are often used for abrasive purposes. The hardness of garnets and their sharp fracture make them suitable as abrasives for wood, leather, glass, metals, and plastics.

Healing Properties

  • Garnet is supposed to be an excellent assistance for blood deficiency diseases. It stimulates bloodstream and pituitary gland, relieves rheumatism and arthritis pain.
  • It is believed that if a garnet is put under a pillow it will cure depression and impure thoughts
  • Garnet gives energy and courage. It is said to encourage robust good health and sexual desire.
  • The stone is also believed to enhance the wearer’s imagination.
  • The Garnet is known as the stone for a successful business.
  • Asiatic tribes carved garnets into bullets in the belief that their fiery color would inflict more deadly wounds.
  • They were ground into powder for the treatment of fever or jaundice. If the cure didn’t work, the apothecary was accused of using an imitation.

So that was all about metaphysical and healing properties of garnets, next we would be discussing on how to take care of garnet and garnet jewelry.

Here comes another post on Garnet for Gemstone Each Month Series (GEMS) – January. We would be discussing history behind Garnets and its applications these days.

Garnet are one of the world’s most ancient gems, it has been known to Man for thousands of years. Garnets are also found in jewellery from early Egyptian, Greek and Roman times. Many an early explorer and traveller liked to carry a garnet with him, for the garnet was popular as a talisman and protective stone, as it was believed to light up the night and protect its bearer from evil and disaster

Applications :-

  • From ancient times the artisans created beautiful garnet beads, bracelets and other jewelry.
  • Garnet sand is a good abrasive, and a common replacement for silica sand in sand blasting.
  • Garnets are said to have been used by Asiatic tribes in place of bullets.
  • They were especially used inlaid in gold cells in the cloisonné technique, a style often just called garnet cloisonné, found from Anglo-Saxon England, as at Sutton Hoo, to the Black Sea
  • During the latter part of the 19th century, garnet bracelets and brooches were particularly popular.
  • The Garnet group is a key mineral in interpreting the genesis of many igneous and metamorphic rocks via geothermobarometry.

So that was all about Garnets history and its application, wait for more to come on Garnets this month. If you have anything to share on Garnets, do email us at info@jewelstruck.com

GEMS January – Mines and Types of Garnet

by JewelStruck on Jan.20, 2010, under GEMS

http://blog.jewelstruck.com/wp-content/plugins/sociofluid/images/digg_48.png http://blog.jewelstruck.com/wp-content/plugins/sociofluid/images/reddit_48.png http://blog.jewelstruck.com/wp-content/plugins/sociofluid/images/stumbleupon_48.png http://blog.jewelstruck.com/wp-content/plugins/sociofluid/images/delicious_48.png http://blog.jewelstruck.com/wp-content/plugins/sociofluid/images/technorati_48.png http://blog.jewelstruck.com/wp-content/plugins/sociofluid/images/google_48.png http://blog.jewelstruck.com/wp-content/plugins/sociofluid/images/myspace_48.png http://blog.jewelstruck.com/wp-content/plugins/sociofluid/images/facebook_48.png http://blog.jewelstruck.com/wp-content/plugins/sociofluid/images/twitter_48.png

Here we are, with another post in Gemstone Each Month Series (GEMS) on Garnets, for the month of January. We did some research on the mines and types of garnet, would be discussing the same in this post.

Garnets are usually mistaken as a single gem, but it is actually a family of gems. They are found all over the world including Latin America, Africa, India, Australia, Asia and some parts of Europe. The most common color of garnets is reddish brown whereas the most prized garnet is an emerald green variety called demantoid and is a member of the adradite group. Garnets are many a times found in the streams where metamorphic rock has eroded and left crystals for collection.

Types of Garnet used as gems are –

  • Pyrope – (from the Greek pyrōpós meaning “fire-eyed”) is red in color and chemically a magnesium aluminium silicate, though the magnesium can be replaced in part by calcium and ferrous iron. The color of pyrope varies from deep red to almost black. Transparent pyropes are used as gemstones. A variety of pyrope from Macon County, North Carolina is a violet-red shade and has been called rhodolite, from the Greek meaning “a rose.” In chemical composition it may be considered as essentially an isomorphous mixture of pyrope and almandine, in the proportion of two parts pyrope to one part almandine. Pyrope is an indicator mineral for high-pressure rocks.
  • Almandine –  sometimes incorrectly called almandite, is the modern gem known as carbuncle. The name Almandine is a corruption of Alabanda, a region in Asia Minor where these stones were cut in ancient times. Chemically, almandine is an iron-aluminium garnet, the deep red transparent stones are often called precious garnet and are used as gemstones (being the most common of the gem garnets).
  • Spessartine Spessartine or spessartite is manganese aluminium garnet. Its name is derived from Spessart in Bavaria. It occurs most often in granite pegmatite and allied rock types and in certain low grade metamorphic phyllites. Spessartine of an orange-yellow is found in Madagascar. Violet-red spessartines are found in rhyolites in Colorado and Maine.
  • Grossular – Grossular is a calcium-aluminium garnet, though the calcium may in part be replaced by ferrous iron and the aluminium by ferric iron. The name grossular is derived from the botanical name for the gooseberry, grossularia, in reference to the green garnet of this composition that is found in Siberia. One of the most sought after varieties of gem garnet is the fine green grossular garnet from Kenya and Tanzania called tsavorite. This garnet was discovered in the 1960s in the Tsavo area of Kenya, from which the gem takes its name.
  • Andradite – is a calcium-iron garnet, is of variable composition and may be red, yellow, brown, green or black. The recognized varieties are topazolite (yellow or green), demantoid (green) and melanite (black). Andradite is found both in deep-seated igneous rocks like syenite as well as serpentines, schists, and crystalline limestone. Demantoid has been called the “emerald of the Urals” from its occurrence there, and is one of the most prized of garnet varieties. Topazolite is a golden yellow variety and melanite is a black variety
  • Uvarovite – Uvarovite is a calcium chromium garnet. This is a rather rare garnet, bright green in color, usually found as small crystals associated with chromite in peridotite, serpentinite, and kimberlites. It is found in crystalline marbles and schists in the Ural mountains of Russia and Outokumpu, Finland. Uvarovite crystals are generally too small to facet and are left attached to a matrix and incorporated into jewelry.

So those were the six major types of Garnets. Hope you got enjoyed reading this post, if you would like to contribute or share anything on Garnets do email us at info@jewelstruck.com.

With our second post on Gemstone Each Month Series (GEMS) for January, we would be talking about basic information on Garnets. Also accompanied by a very beautiful handmade Garnet bead ring in silver by Maura Nicholson.

Garnets are actually one of the largest families of gemstones of related minerals rather than a single gemstone. The  group includes a group of minerals that have been used since the Bronze Age as gemstones and abrasives. Each having common crystal structure, and similar chemical composition.

Though garnets are mostly seen in red color, but with the exception of blue it is found in every color of the spectrum. Garnets family is also rich in rarities such as star garnets and stones whose colour changes depending on whether they are seen in daylight or artificial light.

Most natural garnets are mixtures of two or more of the following pure species: pyrope, almandine, spessartine, uvarovite, grossular, andradite. The best known type of garnet is red semi-precious stone pyrope, one of several red gems. The ancient people used to call this as Carbuncles.

The name “garnet” may come from either the Middle English word gernet meaning ‘dark red’, or the Latin granatus (“grain”) something like ‘the grainy one’, possibly a reference to the Punica granatum (“pomegranate”), a plant with red seeds similar in shape, size, and color to some garnet crystals.

Well that was very basic info about Garnets, we would be discussing more stuff with coming posts in this series including – properties, types, history, applications etc of garnet.
