History and Lore
Ancient and Traditional Associations
The association of gemstones with the months of the year has a long and complex history, with roots in ancient traditions. The use of gemstones as protective and symbolic talismans dates back to civilizations such as the ancient Egyptians, Greeks, and Romans. These cultures often assigned specific stones to the months, believing they carried unique energies and protective powers.
In the case of July, ruby has been a prominent birthstone since ancient times. The ruby was considered a symbol of nobility, power, and vitality. In ancient Poland, Russia, and Tibet, ruby was traditionally assigned to July, reinforcing its status as a timeless gem. Additionally, the sardonyx, a banded stone composed of sard and onyx, was an important July birthstone in ancient Russia, valued for its protective qualities.
In the traditional European system, July was also associated with onyx and turquoise. Onyx, known for its grounding and protective properties, was considered a powerful talisman for those born in the month. Turquoise, with its striking blue-green hues, was often linked to spiritual insight and protection in various ancient cultures, including the Persian and Native American traditions.
Modern and Cultural Variations
The modern July birthstone is ruby, a designation that has been widely accepted in both the United States and the United Kingdom. This tradition was formalized in the early 20th century, when organizations such as the American National Association of Jewelers (now the Jewelers of America) standardized the list of birthstones. Ruby was chosen for its rarity, hardness, and vibrant red color, which symbolizes passion and vitality.
However, other cultures and systems have their own variations. In India, for example, sapphire is considered the July birthstone in the Hindu tradition, representing wisdom and spiritual truth. In Britain, carnelian is sometimes presented as an alternative July birthstone, particularly in older lists. Carnelian, with its warm reddish-orange tones, was historically associated with courage and energy, making it a fitting counterpart to ruby.
The inclusion of multiple birthstones for July reflects the diverse cultural influences that have shaped gemstone traditions over time. While ruby remains the most widely recognized July birthstone, the inclusion of others such as carnelian, onyx, and sardonyx highlights the richness of this month’s gemstone lore.
Geological Formation and Sources
Ruby
Ruby is the most iconic July birthstone, and its formation is a fascinating process. Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The red color of ruby is due to the presence of trace amounts of chromium. Corundum forms in metamorphic rocks, particularly in mica schists and marble, under high-pressure and high-temperature conditions.
The most famous ruby deposits are found in Myanmar (Burma), where the gemstone has been mined for centuries. Burmese rubies are known for their exceptional color and fluorescence, often described as "pigeon blood" red. Other notable ruby sources include Thailand, Sri Lanka, Madagascar, and Vietnam. The secondary colors of pink, orange, and violet in rubies can indicate their origin, making these color variations important in gemology.
Carnelian
Carnelian is a variety of chalcedony, which is a form of microcrystalline quartz. It is characterized by its warm reddish-orange color, which is due to the presence of iron impurities. Carnelian forms in sedimentary rocks and is often found in nodules within volcanic rocks. The primary sources of carnelian include Brazil, India, and the United States. Carnelian has been used in jewelry and decorative objects for thousands of years, and its durability makes it suitable for carving and engraving.
Onyx
Onyx is another variety of chalcedony, known for its banded appearance. It is composed of layers of chalcedony in different colors, most commonly black and white. Onyx forms in sedimentary rocks and is often found in geodes and veins. The primary sources of onyx include Brazil, India, and the United States. Onyx has been used in jewelry and as a decorative stone for centuries, with its contrasting bands making it a popular choice for cameos and intaglios.
Sardonyx
Sardonyx is a banded stone composed of sard (a reddish-brown chalcedony) and onyx (a white or black chalcedony). It is formed through the same geological processes as onyx and is often found in the same regions. Sardonyx was particularly valued in ancient Rome and Greece, where it was used as a protective talisman and for engraving. The primary sources of sardonyx include Brazil, India, and the United States.
Turquoise
Turquoise is a hydrated phosphate of aluminum and copper. It forms in the oxidation zones of copper deposits, typically in arid regions. The most famous turquoise deposits are in the southwestern United States, particularly in Nevada and New Mexico. Turquoise has been used in jewelry and decorative objects for thousands of years, with its blue-green color symbolizing protection and spiritual insight.
Sapphire
Sapphire is a variety of corundum, like ruby, but with a blue coloration due to trace amounts of iron and titanium. It forms in metamorphic and igneous rocks under high-pressure and high-temperature conditions. The primary sources of sapphire include Sri Lanka, Thailand, and Myanmar. Sapphires have been prized for their beauty and durability for centuries, and their association with wisdom and spiritual truth makes them a fitting July birthstone in some traditions.
