This process can occur naturally, as in the case of mountain building or the formation of metamorphic rocks. It can also be induced artificially, as in the case of certain industrial processes.

Chrome diopside is a type of calcium magnesium silicate, which means that it is composed of calcium, magnesium, and silicate minerals. It is often found in rocks that have a high silica content, such as marble or gneiss. In addition to its distinctive green color, chrome diopside is also known for its hardness and durability. It has a Mohs hardness of 5.5 to 6, which makes it relatively hard and resistant to wear and tear.

One of the most well-known deposits of chrome diopside is located in the Ural Mountains of Siberia. This deposit was first discovered in the late 1800s and has been mined for the gemstone ever since. In addition to Siberia, chrome diopside can also be found in Canada, particularly in the Thunder Bay region of Ontario. Here, the gemstone is found in what are known as “diopside pipes,” which are ancient volcanic pipes that were formed millions of years ago.

Another interesting aspect of the geology of chrome diopside is its association with other minerals. In some cases, it can be found alongside other gemstones such as diamond, emerald, and ruby. It can also be found in the same rock formations as other minerals, including pyroxene, amphibole, and olivine.

What are Birth Stone’s, and why do we wear them?

Birth stones are gems that are associated with a birth month. These 12 stones are so popular, that if you ask someone: “What’s your birth stone”? They will almost always know the answer.

The origins of birth stones date back to the1st and 5th centuries.  It is believed that in these times, people began linking gems to the 12 months of the year and to the 12 signs of the zodiac. These stones were presumed to have special powers if worn during each corresponding astrological month. The belief was so strong that people began to collect all 12 stones to wear each month.

It is thought that associating of one gem to each month began in Poland in the 18th century, and these stones are known as the traditional birthstones. In the U.S., there was much disagreement between which stone is assigned to each month so, in an effort to standardize birthstones, The National Association of Jewelers (now known as Jewelers of America) got together and officially adopted a list in 1912. These are known as modern birthstones.

As you can see, the custom of wearing your birth stone is only a few centuries old.  Jewelers are still making changes to the birth stone charts, and as a result, some people choose stones from both the modern and the traditional list.

In honor of July, lets talk about the Ruby

The traditional and modern birth stone of July is the ruby.  This red gem is associated with love, passion, wealth, and peace.  The ruby is one of the most popular traditional jewelry stones.  It is custom for a person to wear their birth stone all year long weather it be in a ring, necklace, or earrings. 

While it is believed wearing your birth stone is a symbol of good fortune and wellness, it is my belief that each person selects a gemstone that calls to them.  If you want a protective stone that can bring happiness and spiritual vitality into your life, just wear a ruby, even if it isn’t your birth stone.
