January Birthstone



 ~  Garnet~
The January birthstone is the beautiful garnet, at least I think it is beautiful…having said that over the years it hasn’t been a popular stone, especially the deep red…I’m not sure why that is?   As always point form is easier and faster to read…

  • Garnet is a group of minerals, not one stone
  • Comes in a rainbow of colors, ranging from deep red, multi shades of green, yellow, blue, blue-green,(although I’ve read garnet does not come in blues, but the stone turns blue in artificial light) vivid orange, earth and umbra shades.
  • Garnet comes from the word granatum, which means seed…it is called this as it resembles the  pomegranate seed
  • Also found the reference that garnet comes from the word granum, meaning gain…which is supposed to refer to the rounded shape.
  • It is thought the Egyptians used garnet in jewelry dating back to 3100 B.C.
  • Hard and sturdy, easy to work with and wear
  • Garnet is not enhanced!
  • In 1996 Sotheby’s sold a garnet flower broach(19th century) from the estate of Jacqueline Kennedy-Onassis for $145.000.00
  • 1996, in central Australia a giant rough garnet estimated to weigh thousands of tons, measuring nearly a hundred feet across was found by a university student.
 This Grossular Garnet Specimen is from Sierra Del Cruz in Coahuila, Mexico. This specimen exhibits pretty "raspberry" Grossular Garnets in a Wollastinite Matrix.

Garnet...January Birthstone!

I can't believe I'm doing this but here goes...for this month at least I'm doing my gemstone post at the beginning of the month, instead of at the end or in the next month!

Hope everyone had a wonderful, safe, happy holiday season...may 2009 be joyful and prosperous for all!!

Garnet...this gemstone has always been somewhat mysterious to me...not sure why...just has! When we think of garnet we think of the rich red, pomegranate colored stone...which is where the name comes from...the Latin for "granatum malum", which means pomegranate. In fact the garnet comes in almost every color...

I found garnet referred to as the Garnet Group, due to the fact the stones included have a similiar crystal make up and formed with similar chemical formulation...amongst which are the following stones:

"PYROPE: (Greek - fiery) blood red, frequently with brown tint, popular in the 18th and 19th centuries. Deposits found in Buma, China, Madagascar, Sri Lanka, South Africa, Tanzania and the United States. Also included in this group is Rhodolite, a bright purplish red or rose-color garnet, is viewed as a more superior gem than Pyrope and Almandite.

ALMANDITE: Deep red, red with violet tint, even black...its name was derived from the town in Asia Minor. Deposits found in Brazil, India, Madagascar, Sri Lanka, Czech Republic, Austria and the United states.

These are garnets with a violet tint which I have in stock at the moment...deeper color , with visible darker inclusions...with a definite violet cast.

SPESSARTITE: Orange to red-brown...Its name is derived from occurrence in the Soessart(=forest), Germany. Deposits are found in Burma, Brazil, China, Kenya, Madagascaar, Sri Lanka, Tanzania, and the United States but the best specimens come from Namibia,("Mandarin Spessartite") which is a bright orange color.

This is red-brown Spessartite Garnet on Quartz Druzy from China...


All three of the following photos are examples of stunning orange Spessartite Quartz on fabulous Smokey Quartz. All gemstones are from China.



The next photo is the Spessartite garnet on Quartz Druzy

GROSSULARTE(Grossular): Colorless, green, yellow, brown...Latin-gooseberry, deposits are found in Canada, Kenya, Mali, Pakistan, Russian (Siberia), Sri Lanka, South Africa, Tanzania and Vermont. Also includes Hessonite, Leuco garnet, Hydrogrossular and Tsavorite.

Hessonite: also called cimmamon stone and Kaneel stone...brown-orange to brown-yellow . Deposits found in Sri Lanka, Brazil, India, Canada, Madagascar, Tanzania and the United States.

Leuco garnet: Colorless...deposits found in Canada, Mexico and Tanzania.

Hydrogrossular: (also falsely called Transvall jade and garnet jade) Dense, translucent to opaque gooseberry-greenish color. Pink hydrogrossular garnet can also be found...as well black inclusions are common. Deposits are in South Africa, Burma, and Zambia.

This Grossular Garnet specimen is from Sierra Del Cruce in Cohuila, Mexico. This specimen exhibits pretty "raspberry" Grossular Garnets in Wollastinite Matrix.

These are garnets with a pink cast to them which I have in stock at the moment...not the deep blood red color...lighter more translucent.


Tsavorite: (Tscvgsavolite) Lime green to emerald green. from Kenya and Tanzania; discovered in the early 1970s.

ANDRADITE: named after a Protuguese mineralogist...varieties include the following...

Demantiod: the most valuable garnet(name means "diamond-like luster")...green to emerald green. Deposits found in China, Korea, Russian, United States and Zaire.

Melanite: Opaque black variety, (Greek-black). Deposits are in Germany (Kaiserstuhl/Baden-Wurttember), France, Italy and Colorado. Used for mourning jewelry.

Topazolite: Yellow to lemon yellow, topaz-like(therefore the name). Deposits found in Switzerland, the Italian Alps and California.

UVAROVITE: Emerald-green. Named after a Russian statesman, Rarely occurs in gemstone quality. Deposits found in Finland, India, Canada, Poland, Russian (the Urals) and California.

Finally we have "color change garnet" these garnets can appear green-blue in daylight (fluorescent light) and magenta-red in incandescent ( artificial )light. Others change from red-purple to yellow-red. The stones are a mix of pryope and spessaritite garnet and are very rare!!" The rarest of them all, discovered in the late 1990's is the "blue garnet", found in Bekily, Madagascar".

It is amazing all the different garnets available...I was very surprised when I read this information!

As an added feature I would like to introduce the healing aspects of gemstones, it is something I've become interested in due to customers asking questions...when I don't know the answer I always like to do research and be ready the next time someone asks me a similar question!

Garnet is recommended as a helpful stone for heart trouble and inflammation...I have arthritis and other inflammation so I just might make myself something with garnet!

There are so many different minerals in the Garnet Group each one will have it's own specific property but to summarize here is a great explanation...a direct
quote from the following booklet which I received in the mail today "The Care and Use of Crystals for Healing by Valerie Smith" from Peaceful Arts For Your Mind, Body & Spirit website.
This great booklet was sent to me by a friend...and I thank her! The quote is as follows...

"uplifting energy causing acceptance and balance of current life - inspires love and devotion - brings courage to seemingly hopeless circumstances - helps one to release old and sabotaging behavior patterns - bestows self-esteem"

Great information...I have a couple of interesting detailed books on healing properties, etc., but this booklet is straight to the point without being technical...Valerie's booklet also states:
"The information in this booklet is not meant to diagnose or replace medical advice. As always use your discretion when seeking help for any medical condition"...
Thank you Valerie.

There you have it...as always I hope you learned something new and interesting as well as enjoyed the stunning photos taken by OJ...
Cheers
