History and Lore of the Diamond
The human love for the April birthstone began in India, where diamonds were gathered from the country’s rivers and streams. These precious stones were traded as early as the fourth century BCE, coveted by royalty and the wealthy. The allure of the diamond was so great that caravans transported these gems, along with other exotic merchandise, to medieval markets in Venice. By the 1400s, diamonds had transitioned from rare commodities to fashionable accessories for Europe’s elite. A pivotal moment in the diamond's history occurred in 1477, when Archduke Maximillian of Austria presented the first recorded diamond engagement ring to his betrothed, Mary of Burgundy, forever linking the gem with romantic commitment.
As India's diamond supplies began to decline in the early 1700s, Brazil emerged as an important new source, ensuring the continued flow of these precious stones to the European market. The history of specific, legendary diamonds also adds to the gem's mystique. Recent evidence supports the origin of the legendary 45.52-carat blue Hope diamond in India’s Golconda mining area. This famous stone was sold to King Louis XIV of France in 1668, where it was known as the French Blue diamond.
Ancient beliefs about the diamond were deeply rooted in mythology and superstition. The Greeks believed diamonds were the tears of the gods, their beauty and rarity suggesting a divine origin. They were also responsible for the name "adamas," signifying indestructibility. The Romans were convinced that diamonds were splinters of the stars. In India, diamonds were used as eyes in statues of their gods, imbuing the deities with vision and power. During the Middle Ages, a diamond was tied under the left arm of a knight to grant him invincibility in battle. These historical accounts highlight the diamond's long-standing association with power, protection, and the supernatural.
Geological Formation and Global Sources
The formation of a diamond is a geological marvel, requiring specific and extreme conditions. Diamonds are composed of carbon atoms arranged in a crystal lattice structure, a process that occurs deep within the Earth's mantle. They are formed under high temperature and excessive pressure, which crystallizes the carbon into the hardest natural material known. This deep-earth origin is the source of the diamond's remarkable physical properties.
The journey from formation to discovery is a long one. Diamonds are brought to the Earth's surface through volcanic activity, embedded in a type of igneous rock known as kimberlite or lamproite. The initial discovery and mining of diamonds occurred in India, where they were found in riverbeds and streams. As mentioned, this source eventually declined, and Brazil became a significant producer in the 18th century. Today, the primary sources of diamonds have shifted again. Modern diamond mining is concentrated in regions such as (South) Africa and Russia. It is worth noting that while Amsterdam is famously known as the "City of Diamonds," this is due to its historical role in the cutting and polishing trade, not because diamonds are originally found there.
Gemological Properties of Diamond
The diamond is distinguished from all other gemstones by its exceptional physical and optical characteristics. Its most defining property is its hardness. Ranking as a 10 on the Mohs scale of mineral hardness, diamond is the hardest natural substance known to man. It is reported to be 58 times harder than any other naturally occurring material. This extreme durability is a direct result of its tightly bonded carbon lattice. This physical property gives rise to many of the stone’s symbolic associations, such as strength, invincibility, and endurance. It can only be scratched by another diamond.
Beyond its hardness, the diamond possesses superior brilliance and the most outstanding reflection of all gems. Its internal fire and scintillation are what make it so highly sought after. The art of maximizing this brilliance through faceting was a significant historical development. Hindu lapidaries discovered that diamond could be polished by using crushed particles of other diamonds, though they only polished regular sides. The modern art of faceting diamonds to enhance their reflection of light was discovered in 1456 by De Berghen, a lapidary from Bruges, who experimented with diamonds belonging to the Duke of Burgundy.
Color is another critical gemological property. While the most recognizable diamonds are sparkling and clear, the gem occurs in a wide range of colors, including brown, yellow, red, pink, blue, and green. The color of a diamond is determined by its impurities. Blue, green, and red diamonds are the rarest. Most diamonds used as gemstones are transparent and colorless, but fancy-colored diamonds are highly prized for their rarity and unique beauty. The chemical composition is pure carbon, and its crystal structure is isometric, which contributes to its isotropic nature and single refractive index.

Symbolism and Metaphysical Beliefs
The diamond's symbolism is as multifaceted as the gem itself. Its name, derived from the Greek adamas, fundamentally symbolizes invincibility and unbreakability. This core meaning has been interpreted in various ways throughout history. It has come to represent strength, power, magic, and beauty. In ancient India, diamonds were believed to be the eyes of gods, suggesting divine insight and protection. The practice of placing a diamond under a knight's arm was a belief in its power to grant invincibility. It was also thought to offer protection from evil, poisoning, and diseases, and was considered a powerful aphrodisiac.
In the context of love and relationships, the diamond is the ultimate symbol of eternity and eternal love. Its association with engagement rings, which began with Archduke Maximillian, has solidified its status as a token of unbreakable bonds and commitment. It represents clarity of mind and emotional balance. Spiritually, diamonds are thought to enhance alignment and resilience. For individuals born in April, the diamond serves as a beacon of clarity and invincibility, with attributes that perfectly complement the strength and determination often associated with this birth month. Its status as "the king of kings" in the gem world is a testament to its superior brilliance and the powerful meanings projected onto it across cultures and eras.
Caring for Your Diamond Birthstone
Given its exceptional hardness, a diamond is a durable gemstone suitable for everyday wear, such as in an engagement ring. However, proper care is still essential to maintain its brilliance and prevent damage to the setting or the stone itself. To maintain a diamond’s sparkle, regular cleaning and proper storage are necessary. Gentle cleaning solutions can be used to remove oils and dirt that accumulate on the surface, which can dull its appearance. It is recommended to use a soft brush and a mild detergent or a commercial jewelry cleaner.
When storing diamond jewelry, it is crucial to keep diamonds in individual cases or soft pouches. Although diamond is the hardest material, it can scratch other softer gemstones or even other diamonds if they are allowed to rub against each other. For this reason, it is best to keep diamond pieces separate from other jewelry. When selecting diamond jewelry, it is also important to consider the vital aspects of cut, clarity, carat, and color to ensure the quality and value of the piece. For those seeking a more budget-friendly option, lab-grown diamonds offer a stunning and ethically produced alternative without compromising on the physical and optical properties of a natural diamond.
