Ever wonder why some months have multiple birthstones while others have just one or even three? The reason lies in the distinction between modern and traditional birthstones.

Modern birthstones, the more commonly known variety, were officially designated by the Jewelers of America in the 1950s. These are the gemstones most people recognize today. Traditional birthstones, on the other hand, were widely accepted in the early 20th century and even earlier. However, many of these traditional gems have become rare and less available in today’s market.

As a result, some months feature modern birthstones that differ from their traditional counterparts. For July, this means celebrating both the vibrant Ruby and the mysterious Onyx, each bringing its own unique beauty and history to the table.

The Radiance of Rubies

For those born in July, the modern birthstone is the magnificent Ruby. The name “ruby” is derived from the Latin word “rubeus,” meaning “red.” Over time, this evolved into “rubinus” in Medieval Latin, “rubi” in Old French, and finally, “ruby” in English.

In Ancient Sanskrit, ruby is called “ratnaraj,” which translates to “king of precious stones.” So, July babies, you can proudly claim that your birthstone is indeed the most precious!

Rubies are one of the four most famous and precious gemstones, standing alongside emeralds, sapphires, and diamonds. Known for their blood-red color, rubies belong to the corundum gem family, which also includes sapphires.

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

Rubies exist only in shades of red and pink. Their vibrant red hue is due to the presence of chromium. The more chromium in the stone, the redder it appears. In some cases, high chromium levels can give the ruby a deep red color with hints of purple or blue under certain lighting conditions. Ironically, chromium also contributes to the rarity of rubies, as it causes fissures and cracks within the gemstone. This chemical paradox makes high-quality rubies in large sizes extremely rare, driving their value even higher than that of diamonds.

Delving into the history of rubies, one of the oldest known sources is Myanmar. Other significant sources include Vietnam, India, East Africa, the Middle East, Thailand, and the United States. Each region produces unique varieties of rubies, with five major types being the Burmese ruby, Thai ruby, Mozambique ruby, Madagascar ruby, and Tanzanian ruby, all highly prized in jewelry.

Throughout history, these radiant red gemstones have been associated with good fortune, health, wisdom, and success in love, particularly in Medieval Europe. Some believe rubies possess healing powers, protecting their owners from harm and illness. These powers were thought to include regenerating the physical and spiritual heart, enhancing circulation, and strengthening immunity for both body and mind. While these beliefs are ancient, the ruby remains one of the strongest gemstones, second only to the diamond.

Embrace the rich history and symbolism of rubies, a gemstone that has captivated hearts and minds for centuries.

Emeralds, though stunning, are the softest and most delicate of the precious gemstones, with a hardness rating of 7.5 to 8 on the Mohs scale. While this hardness is generally adequate for jewelry, emeralds often contain inclusions and fractures that may reach the surface, increasing their susceptibility to brittleness and breakage. This is especially crucial to remember if your emerald is set in high-impact pieces like rings or bracelets, which typically endure more wear and tear due to their placement on the hands and wrists.

Taking proper care of emeralds is vital. Most emeralds are treated with oil, and sometimes resin, to enhance their appearance by masking imperfections and boosting their color. To clean your emeralds, simply rinse them in warm water and pat dry with a soft cloth. Avoid using chemicals, heat, or ultrasonic cleaners, as harsh cleaning methods can remove the oil treatment from the gemstone. Should the oil be stripped, some jewelers offer re-oiling services to restore their luster.

The enchanting Agate, a traditional birthstone of May, traces its roots back to ancient Greece and Rome. This gemstone’s name originates from its first known location of mining, the Achates River in Sicily, over 3000 years ago.

Agates set themselves apart from other crystal gemstones by their uniqueness—no two stones are alike. As a variety of Chalcedony, which belongs to the Quartz family, agates exhibit a micro-crystalline, compact form. To qualify as an agate, the stone must display distinctive banding or wavy patterns of vein bands within the mineral rock. The clarity and sharpness of these bands significantly enhance the stone’s value.

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.

Agates dazzle in a spectrum of colors including green, red, yellow, blue, pink, brown, white, black, and even translucent and fluorescent hues. Each stone’s unique coloration and patterning arise from mineral traces such as iron, nickel, chromium, titanium oxides, among others. Despite their varied appearance, some patterns recur, such as the Fire Agate, Eye Agate, and Iris Agate, each with its own distinct allure.

Found in cavities within eruptive rocks or ancient lavas, agates are a global phenomenon, cherished for their incredible diversity and natural beauty.

Agates are not just beautiful natural gems; they are powerful symbols of courage, protection, strength, and balance. Known for their transformative properties, agates can convert negative energy into positive, bringing a soothing and calming presence. Like emeralds, agates are celebrated for their healing qualities, particularly in soothing inner anger and alleviating anxiety. Both agates and emeralds are reputed to foster harmony in relationships.

The fascinating history of agates stretches back to Ancient China, where these stones were once believed to be fossilized horse brains or the remnants of blood spilled in battles. During the Renaissance, the allure of agates surged as collecting agate cups became a prestigious hobby among the elite. This storied past highlights the enduring allure and mystical qualities of agates, making them a treasure in both historical and modern contexts.

Agates are impressively durable, boasting a hardness of 6.5 to 9 on the Mohs scale. For context, consider quartz, which ranks between 7 and 7.5 and is commonly found in household dust. This seemingly innocuous dust can strip the polish off your table and the finish from your car due to its hardness. At the top of the scale is the diamond, with a maximum hardness of 10, while the softest mineral, talc, can be scratched by a mere fingernail. Understanding these hardness levels is crucial for properly caring for your agate jewelry, ensuring that it remains free from scratches and retains its lustrous beauty.

Though generally more affordable, agates are nonetheless stunning and make exceptional centerpiece stones for any type of jewelry. Their rich colors and unique patterns ensure that agate jewelry remains a favorite for those seeking both beauty and durability in their adornments.
