History and Lore
The history of the diamond is as ancient and compelling as the gem itself. The name "diamond" is derived from the Greek word adamas, which translates to "unbreakable" or "invincible." This etymology is a fitting testament to the diamond's status as the hardest natural material known to man, a property that has imbued it with powerful symbolism throughout human history.
Civilizations across the ages have admired the diamond, often regarding it as a potent symbol of power, purity, and eternal love. Its journey into human adornment began in ancient India, where diamonds were first discovered. However, these early gems were not immediately set into jewelry. For centuries, they were valued primarily for their ability to engrave other metals and were believed to possess medicinal properties. It was not until much later that their aesthetic potential was fully realized.
The earliest recorded use of diamonds in jewelry can be traced back to the 14th century, during the era of the Delhi Sultanate in India. It was here that these precious stones began to be incorporated into royal adornments, marking the beginning of their long and storied association with nobility and wealth. As trade routes expanded, diamonds captured the imagination of European royalty and aristocracy, solidifying their position as the ultimate symbol of status and enduring commitment. Over time, this association evolved, culminating in the diamond's modern role as the quintessential stone for engagement rings, representing an unbreakable bond of love.
Geological Formation and Sources
The creation of a diamond is a testament to the immense forces at work within the Earth. These gems are formed deep within the planet's mantle under conditions of extreme heat and pressure—approximately 90 to 120 miles (145 to 193 kilometers) below the surface. Here, carbon atoms are subjected to pressures over 50,000 times that of the Earth's atmosphere and temperatures exceeding 2,000 degrees Fahrenheit (1,093 degrees Celsius). Over millions of years, these conditions force the carbon atoms into a rigid, tetrahedral crystal lattice, the structure that gives a diamond its legendary hardness.
This remarkable process does not create diamonds near the surface. They are brought closer to the Earth's crust through violent volcanic eruptions. These eruptions propel magma upward at high speeds, carrying fragments of the mantle rock—including diamonds—in a rock type known as kimberlite or lamproite. These kimberlite pipes are the primary source of most diamonds mined today. A smaller percentage of diamonds are found in alluvial deposits, having been eroded from their original kimberlite sources over millennia and carried by water to form coastal or riverbed placers.
While diamonds are found in various locations around the globe, certain regions are renowned for their production. Historically, India was the world's primary source of diamonds for centuries. Today, major diamond mining operations are centered in Africa, with countries like Botswana, the Democratic Republic of Congo, and South Africa leading production. Other significant sources include Russia, Canada, and Australia. The specific geographic origin of a diamond can influence its characteristics and, in some cases, its value, though this is often a complex assessment for gemologists.
Gemological Properties
The diamond's status as the "king of gems" is firmly rooted in its exceptional and precisely defined gemological properties. These characteristics are the basis for its grading, valuation, and enduring appeal.
The 4 Cs: A Framework for Value
The value and quality of a diamond are primarily assessed using the internationally recognized "4 Cs" standard: Cut, Color, Clarity, and Carat Weight.
- Cut: This is arguably the most important of the 4 Cs, as it directly influences a diamond's brilliance and fire. The cut refers not to a diamond's shape (like round, princess, or emerald) but to the precision of its facets and proportions. A masterfully cut diamond will reflect light internally from one facet to another and then折射 it back out through the top of the stone, creating its signature sparkle. Poorly cut diamonds may appear dull, as light leaks out from the sides or bottom.
- Color: While many people think of diamonds as perfectly clear, most possess subtle hints of yellow or brown. The Gemological Institute of America (GIA) grades diamond color on a scale from D (colorless) to Z (light yellow or brown). The less color a diamond exhibits, the rarer and more valuable it is considered. However, "fancy color" diamonds, which exhibit strong, distinct colors like pink, blue, or yellow, are a different category and can be exceptionally valuable.
- Clarity: This property refers to the presence of internal or external blemishes, known as inclusions and blemishes, respectively. Nearly all diamonds have these natural characteristics, which are formed during the diamond's creation. The GIA Clarity Scale ranges from Flawless (no inclusions or blemishes visible under 10x magnification) to Included (inclusions and/or blemishes are obvious under 10x magnification and can affect transparency and brilliance). The fewer and less visible the inclusions, the higher the diamond's clarity grade and value.
- Carat Weight: The carat is the standard unit of measurement for a diamond's weight. One carat is equal to 200 milligrams. While larger diamonds are generally rarer and more valuable, price does not increase in a linear fashion. A 2-carat diamond is not simply twice the price of a 1-carat diamond of the same quality; its price increases exponentially because of its greater rarity.
Hardness and Durability
The diamond's most famous property is its hardness. On the Mohs scale of mineral hardness, it ranks as a perfect 10, making it the hardest known natural substance. This exceptional hardness means that a diamond can only be scratched by another diamond, a crucial factor in its longevity as a jewelry stone. It also gives the diamond a high degree of brilliance, as its tightly bonded carbon atoms allow light to pass through it with minimal distortion. This hardness, combined with its lack of cleavage (the tendency to split along a flat plane), makes the diamond an exceptionally durable gem suitable for everyday wear.
Chemical and Physical Characteristics
- Chemical Composition: Pure Carbon (C)
- Crystal System: Cubic
- Refractive Index: 2.417 (This high index is responsible for its exceptional brilliance and ability to bend light significantly)
- Specific Gravity: 3.52 (±0.01)

Care and Cleaning
Given its exceptional hardness, the diamond is one of the most durable gemstones and is well-suited for all types of jewelry, including rings and bracelets that are exposed to daily wear. However, proper care is still necessary to maintain its brilliance.
Cleaning Methods
The best way to clean a diamond is to soak it in a solution of warm water and a few drops of mild dish soap. After soaking for 20-30 minutes, a soft-bristled brush (such as a baby's toothbrush) can be used to gently scrub the stone, paying special attention to the area underneath the setting where oil and grime can accumulate. The diamond should then be rinsed thoroughly in warm water and dried with a soft, lint-free cloth.
Ultrasonic cleaners are also highly effective for cleaning diamonds, but caution should be exercised if the diamond is set in a fragile mounting or if it has significant inclusions. Steam cleaning is generally safe for diamonds but should be avoided if the stone has been treated or if the jewelry setting is not heat-resistant.
Durability and Safety
With a Mohs hardness of 10, a diamond cannot be scratched by any other substance except another diamond. However, its extreme hardness also means it is somewhat brittle and can be chipped or fractured if struck with a sufficient blow at a vulnerable angle, particularly at its girdle or culet. Therefore, it is important to avoid hard blows, such as striking a diamond ring against a granite countertop.
When storing diamond jewelry, it is best to keep it in a separate fabric-lined box or compartment. While a diamond cannot be scratched by other gems, it can easily scratch other jewelry, including other diamonds if they are jumbled together.
