Why does July have two different birthstones?

The months of the year differ from each other as they have different amounts of birthstones, some having only one birthstone, and others even having up to three gemstones associated to the month.

There are different numbers of birthstones per month as there are the associated gemstones that are classified as either modern or traditional. The more common of the two types are modern birthstones, which were officially named by the Jewelers of America in the 1950’s. Traditional birthstones are the gemstones that were more commonly associated with its respective month in the early 20th century and even beyond. Many of these traditional birthstones have become too rare and are not as available on the market in this day and age, and therefore some months have modern birthstones that differ from its traditional associations.

The Radiance of Rubies

Features of Rubies

The modern birthstone of June is the Ruby. The origin of the name “ruby” comes from its Latin word “rubeus,” which means “red.” Through history, the word was adopted as “rubinus” from Medieval Latin and “rubi” in Old Fresh, thus becoming “ruby” in English. The word “ruby” in Ancient Sanskrit is also translated to “ratnaraj,” which is defined as the “king of precious stones.” So you July babies can technically say your birthstone is the most precious!

That being said, the ruby is one of the most famous and four precious gemstones alongside emeralds, sapphires, and diamonds. There is no doubt that it has earned its place amongst the four, being known for its blood-red color. Its red color comes from being the red variety of the mineral corundum gem family, which sapphires are also a part of.

There are no other colors of rubies in the world in existence besides red and pink.

The science behind the red glow of fire that these gemstones give off are caused by the chromium within its properties. The more chromium present, the more red the gemstone will be, with some red colors so deep with impurities that there are hints of purple, and sometimes blue, with the right lighting. Ironically, chromium is also the cause of the rarity of the ruby gemstone itself as it causes fissures and cracks. Due to this chemical paradox, fine quality rubies in large amounts is extremely rare and therefore causes the value of this birthstone to be quite high and well above diamonds.

The History and Symbolism of Rubies

Diving deep into the history of rubies, one of the oldest known sources of rubies comes from Myanmar. Other sources of rubies can be found in Vietnam, India, East Africa, the Middle East, Thailand, and the United States. With all of these different deposit origins, there are also different types of rubies, with five major kinds being Burmese ruby, Thai ruby, Mozambique ruby, Madagascar ruby, and Tanzanian ruby, all commonly recognized in terms of jewelry.

These radiant red gemstones are commonly associated with good fortunate, health, wisdom, and success in love, as they were in Medieval Europe. There are some that believe that the ruby holds a healing power, protecting its owner and bearer from harm and illness. Furthermore, these powers included the regeneration of the physical and spiritual heart as it enhanced circulation and strengthened immunity for the entire body and mind. Although most are ancient beliefs of strong powers, the ruby gemstone is indeed one of the most strongest gemstones, right behind the diamond.

Maintaining and Caring for Your Rubies

Rubies have a hardness of 9 on the Mohs scale of hardness. This makes rubies the hardest of the colored gemstones, and the second hardest when including the diamond. To put this in perspective, quartz has a hardness of 7 – 7.5 and are present in the particles of dust seen floating in the air and settling on uncleaned objects in your home. These particles have the hardness that is able to remove the polish from your table and the finish from your car. Diamond have a hardness of 10, which is the hardest gemstone, and the softest includes talc, which is a gemstone that even your fingernail can scratch.

These minerals can only be scratched by the hardness level above it, so ruby owners wouldn’t need to worry too much unless you’re planning on having diamonds around. However, your precious gemstones still deserve care and maintenance to keep it looking as sparkly and pristine as possible. It is recommended to use warm water and soap and a very soft brush to keep your ruby gemstones clean.

With the ruby being the gemstone associated with the 15th and 40th wedding anniversaries, this stone of love and passion is a great gift for those celebrating those milestones as well as a July birthday!

Optimal Onyxes

Features of Onyxes

Some consider the traditional gemstone of July to be the Onyx. It is more commonly recognized that the Ruby is both the traditional and modern gemstone, but those in the 15th to 20th century did consider the onyx to be one of the July birthstones. In history, the word “onyx” comes from the Latin word, which also was adopted from the Ancient Greek word “onux,” which means “claw” or “fingernail.”

In modern times, most black onyx gemstones that are commercially available are color enhanced through heat and dye to increase the intensity of its color.

The onyx gemstone is very similar to the traditional birthstone of May, which is the agate. These gemstones are both banded stones varieties from the chalcedony group. These black gemstones usually have a black base with intense white band patterns that different between individual stones. There are also red varieties of the onyx in existence that are called the sardonyx.

The History and Symbolism of Onyxes

This optimal gemstone be found in Brazil, India, California, and Uruguay. It is associated to be a gemstone to absorb negative energy, having stronger powers the darker the color is. The onyx is also known to symbolize strength, boldness, balance, and self-confidence, which is perfect for owners and bearers to strengthen their minds. Cleopatra allegedly had worn the dark variety of onyxes for its protective powers and values.

In ancient Greek mythology, there is a legend that says that the goddess Venus fell asleep, and had her fingernails clipped off by Eros, also known as Cupid, her son, which were scattered across the Indus River. As it was believed that no heavenly body part can die, including these fingernails, these clippings were turned into stone which later became known as the onyx.

This gemstone is also associated to the 7th and 10th anniversary years of marriage, so if you’re looking forward to making this anniversary special, we recommend looking into this unique stone. If you or someone you know was born in July, we hope you see onyxes as a wonderful birthstone alternative to the red ruby!

Maintaining and Caring for Your Onyxes

Onyxes have a hardness of 6.5 on the Mohs scale of hardness, which is relatively not that high up there in comparison to the other gemstones like the ruby. Because of this, this gemstone is a good choice for carving.

The care and maintenance for onyx gemstones and jewelry is similar and straightforward in comparison to other gemstone jewelry in terms of using soft material to wipe off any dirt. However, we recommend that you do not wet or soak your onyx gemstone in water as this stone is very porous and absorbs liquids quite easily. Therefore, using a lightly moistened cloth can make things easier to clean your onyx jewelry.

As mentioned before, minerals can only be scratched by the hardness level above it and quartz has a hardness of 7 – 7.5 and are present in the particles of dust seen floating in the air. This level of hardness is also able to remove the polish from your table and the finish from your car. So keep this in mind when caring for your onyx jewelry, as dust and dirt particles would potentially leave a scratch on your precious birthstone.
