History and Lore
The concept of associating gemstones with specific months has ancient roots, though the modern list of birthstones is a product of more recent history. The standardization of birthstones occurred in 1912 when the American National Retail Jewelers Association, now known as Jewelers of America, established an official list. This list has seen updates over the years, with the most recent addition in 2002 when tanzanite was added to the December birthstone lineup. The modern list has remained relatively consistent, with only minor additions. In 2019, for instance, the list was updated to include spinel as an alternative August birthstone alongside peridot and sardonyx, reflecting a growing appreciation for the gemstone historically mistaken for ruby.
While the diamond’s formal status as April’s birthstone is a modern designation, its lore spans centuries. The sources do not provide detailed historical narratives specific to the diamond’s ancient beliefs, but its position as a symbol of enduring value and strength is implicit in its gemological properties and its central role in the standardized birthstone chart. The tradition of birthstones as a whole—spanning continents and cultures—provides a rich backdrop, with the 2023 list serving as a celebration of this tradition, science, and culture. The diamond’s inclusion in this list underscores its timeless appeal, bridging historical reverence with contemporary significance.
Geological Formation and Sources
Understanding the geological formation and sources of birthstones provides valuable insights into their rarity, availability, and market dynamics. The diamond’s formation is a unique and slow process that occurs under extreme conditions. Diamonds form under high pressure and temperature conditions deep within the Earth’s mantle. This process takes millions of years, which contributes significantly to their rarity and value.
The diamond’s journey from the mantle to the surface is also a geological event, typically facilitated by volcanic activity. While the specific mechanisms of transport are not detailed in the provided sources, the locations where diamonds are mined are clearly identified. The primary sources of diamonds are found in countries such as South Africa, Russia, Canada, and Australia. These regions are known for their diamond deposits, which have been the source of many of the world’s most significant gemstones. The geographic distribution of diamond mines highlights the global nature of the diamond trade and the specific geological conditions required for their formation.
Gemological Properties
The diamond is distinguished by a set of gemological properties that make it one of the most coveted and durable gemstones in the world. Its physical and optical characteristics are the foundation of its value and beauty.
Hardness and Durability
The most notable property of the diamond is its extreme hardness. On the Mohs scale of mineral hardness, diamond ranks at the highest level of 10. This makes it the hardest and most durable of all known natural materials. This exceptional hardness is a direct result of its crystal structure and chemical composition. The diamond’s ability to resist scratching and abrasion makes it an ideal gemstone for jewelry that is intended for everyday wear, such as engagement rings and other frequently worn pieces.
Chemical Composition and Structure
The diamond is a mineral composed of a single element: carbon. Its atoms are arranged in a rigid, three-dimensional lattice structure, which is responsible for its remarkable hardness. This simple yet perfect arrangement allows for the efficient transmission of light, contributing to the diamond’s renowned brilliance and fire.
Color and Clarity
While the diamond is often associated with a colorless or white appearance, it can occur in a wide range of colors. The sources note that the diamond is known for its brilliance and fire, which are optical properties resulting from its ability to reflect and refract light. The clarity of a diamond refers to the presence of internal inclusions or external blemishes. The diamond’s value is significantly influenced by the absence of these imperfections, with clearer stones commanding higher prices. The formation process, occurring deep within the Earth, can sometimes result in inclusions, which are natural characteristics that can affect the stone’s clarity and value.
Cut and Carat
While the sources do not provide specific details on diamond cutting styles or the definition of a carat, these are fundamental aspects of gemology. The cut of a diamond refers to the proportions, symmetry, and polish of its facets, which directly impact its light performance. The carat is the unit of weight for gemstones, with one carat equaling 0.2 grams. Larger diamonds are rarer and thus more valuable, all other factors being equal.
The following table summarizes the key gemological properties of the diamond as presented in the provided sources:

Symbolism and Metaphysical Beliefs
The diamond is universally recognized as a symbol of enduring love, commitment, and purity. Its exceptional hardness is often metaphorically linked to the strength and permanence of relationships, which is why it is the traditional stone for engagement rings. While the provided sources focus primarily on the gemological and historical aspects of birthstones, the diamond’s symbolic weight is a well-documented cultural phenomenon. The sources do not elaborate on specific metaphysical beliefs or healing properties associated with the diamond, such as those found in some alternative or New Age traditions. The information provided is grounded in the standardized birthstone list and its scientific properties, presenting the diamond’s significance through its physical attributes and its role in the modern birthstone chart.
Care and Cleaning
The care and cleaning of gemstones are dictated by their physical properties, particularly hardness, cleavage, and stability. The diamond’s exceptional hardness of 10 on the Mohs scale makes it highly resistant to scratching and abrasion. This durability allows for relatively straightforward care compared to softer gemstones.
However, despite its hardness, diamonds are not indestructible. They can be chipped or broken if struck with sufficient force at certain angles due to their cleavage planes. Therefore, while diamonds are suitable for daily wear, they should be protected from hard impacts.
For cleaning, diamonds can be safely cleaned using warm water, a mild detergent, and a soft brush. Ultrasonic cleaners are generally safe for diamonds, but caution is advised for diamonds with significant inclusions or fractures, as vibrations could potentially damage them. Steam cleaning is also effective but should be avoided for diamonds that have been treated or have surface-reaching inclusions. The sources do not provide specific cleaning instructions for diamonds, but general gemological best practices apply, leveraging the stone’s durability. Regular cleaning is recommended to maintain the diamond’s brilliance, as oils and dirt can accumulate on its surface, diminishing its light performance.
Conclusion
The diamond, as April’s birthstone, represents a unique convergence of geological rarity, scientific wonder, and cultural symbolism. Its formation deep within the Earth’s mantle over millions of years results in a gemstone of unparalleled hardness and optical beauty. The standardization of birthstones in the 20th century cemented the diamond’s role as a modern symbol of April, building upon a legacy of value and desirability that spans centuries. Its properties—a Mohs hardness of 10, a carbon-based composition, and a capacity for exceptional brilliance—make it not only a cherished personal adornment but also a subject of ongoing fascination for gemologists and enthusiasts alike.
