History and Lore
The origins of birthstones date back to ancient times, with one of the earliest references found in the biblical Book of Exodus, where the high priest Aaron’s breastplate was adorned with twelve gemstones representing the twelve tribes of Israel. Over time, these stones were associated with the months of the year and later with zodiac signs. By the 14th century, the practice of linking gemstones to months had become widespread in Europe, often influenced by medieval texts and traditions.
For July, the ruby has long been recognized as the primary birthstone. Ancient cultures, particularly in India, revered the ruby as the "ratnaraj," or "king of precious stones." The ruby was believed to bring divine protection, vitality, and prosperity. In European courts, nobility prized rubies for their association with power and bravery. The ruby’s deep red color symbolized life force and passion, making it a popular choice for royal and aristocratic jewelry.
Carnelian, another July birthstone, has a long history of use in ancient civilizations, including Egypt, Greece, and Rome. It was often carved into amulets and seals, used for protection and courage. In medieval Europe, carnelian was believed to enhance energy and vitality, making it a favored stone among warriors and leaders.
Onyx, another historical July birthstone, was used in ancient Egypt and Greece for its protective properties. The Romans often wore onyx rings, believing it brought courage and strength. Sardonyx, a variant of onyx with a reddish-brown base and white bands, was especially popular in Russia and was considered a powerful talisman for optimism and confidence.
Sapphire, the Hindu birthstone for July, symbolized wisdom and spiritual truth. Its blue color was associated with the purity of the soul and was believed to bring peace of mind. Turquoise, another traditional July birthstone, has been used in jewelry and ornamentation for thousands of years, particularly in the Middle East and the Americas. Its blue-green color was seen as a protective and calming force.
These historical associations show that July birthstones have long been valued for their symbolic and spiritual significance. While the ruby has emerged as the primary July birthstone in modern times, the others continue to hold cultural and historical importance.
Geological Formation and Sources
Understanding the geological processes that form these July birthstones provides insight into their rarity and value. Each stone is formed under specific conditions, contributing to its unique properties and color.
Ruby
Ruby is a variety of the mineral corundum, which is composed of aluminum oxide (Al₂O₃). The deep red color of ruby is due to trace amounts of chromium. Rubies are formed in metamorphic rocks such as marble and in igneous rocks like basalt. The most famous ruby deposits are found in Myanmar (Burma), where the stones exhibit a vivid "pigeon's blood" red color and a glowing fluorescence. Other notable sources include Thailand, India, Afghanistan, and Tanzania.
Rubies are known for their hardness, ranking 9 on the Mohs scale, second only to diamond. This high hardness makes them durable and suitable for use in jewelry, though they can still be damaged by impacts or abrasion.
Carnelian
Carnelian is a variety of chalcedony, a form of microcrystalline quartz. It is composed of silicon dioxide (SiO₂) and owes its reddish-orange color to iron impurities. Carnelian is formed in sedimentary and metamorphic rocks and is commonly found in Brazil, India, and the United States. It has a hardness of 6.5 to 7 on the Mohs scale, making it relatively durable but more susceptible to scratches than ruby.
Onyx
Onyx is another variety of chalcedony, with a fine-grained structure and a smooth, waxy luster. It is typically black or white, with alternating bands of color. Onyx is formed in volcanic rocks and is found in countries such as Brazil, India, and the United States. It has a hardness of 6.5 to 7 on the Mohs scale, similar to carnelian. The banding in onyx makes it ideal for cabochon cutting and engraving.
Sardonyx
Sardonyx is a type of onyx with a reddish-brown base and white bands. It is formed in similar geological conditions to onyx and is found in Brazil, India, and Madagascar. The name "sardonyx" comes from the Greek words "sardis," meaning "red," and "onyx." It has a hardness of 6.5 to 7 on the Mohs scale.
Sapphire
Sapphire is another variety of corundum, but it is colored blue due to trace amounts of iron and titanium. While blue is the most common color, sapphires can occur in various colors, including pink, yellow, and green. Sapphires are formed in metamorphic and igneous rocks and are found in countries such as Sri Lanka, India, and Australia. Like ruby, sapphire ranks 9 on the Mohs scale.
Turquoise
Turquoise is a hydrated phosphate of aluminum and copper, with the chemical formula Al₂(OH)₃PO₄·nH₂O. It is formed in arid regions where copper minerals react with water and phosphorus-rich deposits. Turquoise is typically found in the United States, China, and Egypt. It has a hardness of 5 to 6 on the Mohs scale, making it relatively soft and prone to scratches.
The geological origins and sources of these July birthstones highlight their natural beauty and the conditions under which they form. These factors contribute to the rarity and value of each stone, making them highly sought after in the jewelry industry.
