History and Lore
Ancient Origins and Cultural Associations
The diamond’s journey as the April birthstone began long before it was officially designated as such. Ancient civilizations revered diamonds for their unmatched hardness and striking brilliance. The earliest known diamonds were mined in India, where they were discovered around 2500 BCE. These early diamonds were not only admired for their physical beauty but also believed to possess divine and protective powers.
In ancient India, diamonds were often used in religious and ceremonial contexts. They were considered symbols of strength and purity, and were sometimes worn as talismans to ward off evil. As trade routes expanded, diamonds made their way to other parts of the world, including Greece and Rome, where they were associated with the gods of love and fertility, such as Venus (Aphrodite in Greek mythology).
By the 17th and 18th centuries, diamonds had become increasingly popular in European jewelry, particularly in the form of rings and brooches. This growing appreciation culminated in the diamond being officially recognized as the modern April birthstone in the United States and the United Kingdom. The diamond’s symbolic connection to eternal love and enduring strength made it an especially fitting choice for April.
The Diamond and the Zodiac
April straddles two zodiac signs: Aries (March 21 to April 19) and Taurus (April 20 to May 20). The diamond, as a zodiac stone, is most closely associated with Aries, the first sign of the zodiac. Aries is known for its boldness, courage, and determination—qualities that mirror the diamond’s own characteristics of strength and clarity.
The gemstone was also recognized in ancient Hindu (Ayurvedic) traditions as the April birthstone, and in Polish and Tibetan calendars, where it appeared alongside other gemstones like sapphire and opal.
The April Birthstone in Poetry and Literature
The diamond has often been referenced in poetry and literature, particularly in relation to the month of April. One of the earliest recorded references to the diamond as the April birthstone is found in a Gregorian birthstone poem, which reads:
"She who from April dates her years,
Diamonds shall wear, lest bitter tears
For vain repentance flow; this stone,
Emblem of innocence, is known."
This poetic reference highlights the diamond’s symbolic association with innocence and emotional resilience, reinforcing its status as a meaningful and protective gemstone.
Geological Formation and Sources
How Diamonds Are Formed
Diamonds are formed through a process that spans billions of years and occurs under extreme geological conditions. They are composed of carbon atoms arranged in a crystal lattice structure, making them the hardest naturally occurring substance on Earth. The formation of a diamond requires:
- Extreme pressure (between 45 and 60 kilobars)
- High temperatures (around 900 to 1300 degrees Celsius)
- Deep Earth conditions (between 150 and 250 kilometers below the Earth's surface)
Under these conditions, carbon atoms bond in a tetrahedral structure, forming the crystal lattice that gives diamonds their remarkable hardness and brilliance.
Once formed, diamonds are brought closer to the Earth's surface through volcanic eruptions, which create kimberlite pipes—tubular rock formations that act as natural conduits for the gemstone. These pipes are the primary source of diamond mining today.
Major Diamond Sources
Historically, India was the only known source of diamonds for centuries. However, as mining expanded, other regions began to emerge as significant diamond-producing countries. Some of the most notable sources of diamonds today include:
- South Africa – The first major diamond discoveries in the 19th century were made in South Africa, particularly at the Kalahari Diamond Field. This discovery led to a global diamond rush and the rise of the modern diamond trade.
- Russia – In the 20th century, Russia became one of the largest producers of diamonds, particularly from the Yakutia region.
- Canada – Canada has become a prominent source of ethically mined diamonds, with significant deposits in the Nunavut and Northwest Territories.
- Australia – Known for its Argyle Mine, Australia is particularly famous for producing pink and red diamonds, which are among the rarest and most valuable in the world.
These regions continue to supply the global market with diamonds, ensuring that the April birthstone remains a coveted and widely available gemstone.
Gemological Properties
Key Characteristics of the Diamond
Diamonds are distinguished by a set of unique gemological properties that make them highly valued in both the jewelry and gemstone industries. The following are the key characteristics of the diamond:
| Property | Description |
|---|---|
| Hardness | 10 on the Mohs scale (hardest naturally occurring mineral) |
| Refractive Index | 2.417 to 2.419 |
| Specific Gravity | 3.52 |
| Chemical Composition | Pure carbon (C) |
| Crystal System | Isometric (cubic) |
| Color | Can appear in a wide range of colors, including colorless, yellow, brown, pink, blue, and green |
| Luster | Adamantine (exceptionally brilliant) |
| Transparency | Transparent to translucent |
| Cleavage | Perfect octahedral cleavage |
| Durability | Extremely high (due to its hardness) |
The color of a diamond is one of its most notable and variable properties. While colorless diamonds are the most valuable and sought after, diamonds can also occur in a wide array of colors, known as fancy colors. These include:
- Yellow and Brown – The most common colored diamonds, often found in large quantities.
- Pink and Red – Extremely rare and highly valuable, especially those from the Argyle Mine in Australia.
- Blue and Green – Often caused by exposure to natural radiation or trace elements like boron and chromium.
- Black and White – Known as “carbonado” diamonds, they are opaque and usually used in industrial applications.
The 4Cs of Diamond Grading
When evaluating the quality of a diamond, gemologists use the 4Cs system:
- Carat Weight – Measures the weight of the diamond, with 1 carat equaling 200 milligrams. Larger diamonds are rarer and more valuable.
- Color – Ranges from D (colorless) to Z (faint yellow or brown). The more colorless a diamond, the higher its value.
- Clarity – Refers to the presence of inclusions (internal flaws) and blemishes (external imperfections). The clarity grade ranges from FL (flawless) to I3 (heavily included).
- Cut – Determines the diamond’s brilliance and sparkle. A well-cut diamond maximizes light reflection and creates a dazzling appearance.
These four factors collectively determine a diamond’s overall value and desirability, especially in the context of jewelry and fine gemstone collections.

Care and Cleaning
Proper Maintenance for Longevity
Due to its exceptional hardness, the diamond is one of the most durable gemstones, but it is not indestructible. To ensure the longevity of a diamond and maintain its brilliance, proper care and cleaning are essential.
1. Cleaning Methods
There are several safe and effective ways to clean a diamond:
- Warm, Soapy Water – This is the most common and gentle method. Simply mix a few drops of mild dish soap with warm water and soak the diamond for 20 to 30 minutes. Gently scrub with a soft-bristled brush, then rinse with lukewarm water and pat dry with a soft cloth.
- Ultrasonic Cleaners – These devices use high-frequency sound waves to clean the diamond and remove dirt and grime. They are generally safe for diamonds, provided the diamond does not have any cracks or fractures that could be exacerbated by the vibrations.
- Steam Cleaners – Similar to ultrasonic cleaners, steam cleaners use heat and water vapor to clean the gemstone. They are also safe for diamonds, as long as the diamond is free of structural weaknesses.
2. Storage and Handling
Diamonds should be stored in a soft, lined jewelry box to prevent scratches and damage. It is also advisable to store diamonds separately from other gemstones, as their hardness can potentially scratch softer stones like emeralds or rubies.
When handling a diamond, it is best to do so with clean hands to avoid transferring oils or dirt onto the gemstone. Avoid wearing diamonds in situations where they may be exposed to extreme heat, chemicals, or impact, such as during physical activities or chemical exposure (e.g., chlorine in swimming pools).
3. Professional Inspection and Maintenance
Even though diamonds are highly durable, it is a good idea to have them professionally inspected once a year by a certified gemologist or jeweler. This ensures that the diamond remains in optimal condition and that any potential issues—such as loose settings or internal fractures—are identified and addressed early.
