What Is Diamond?

Diamond is a naturally occurring mineral that is composed of pure carbon. It is the hardest substance known to man and is one of the world’s most valuable and sought-after gems. The crystal structure is unique, giving it its exceptional hardness, high thermal conductivity, and high refractive index, making it one of the most brilliant gems.

They are formed deep within the earth’s mantle under extreme pressure and temperature. They can also be found in alluvial deposits, where they have been eroded from their source and deposited in riverbeds and on the ocean floor.

They are available in many colors, including colorless, yellow, pink, blue, green, and black. In addition, they can be cut and polished into various shapes and sizes, making them versatile and adaptable for use in jewelry.

How is Diamond Formed?

Diamonds are formed deep within the earth’s mantle, over 100 miles below the surface, under extreme pressure and temperature conditions. They are believed to be formed from carbon-rich material brought to the surface through volcanic eruptions. This carbon-rich material cools and solidifies into a crystal structure.

There are two types of formation: primary and secondary. Primary diamonds are formed deep within the earth’s mantle. Secondary diamonds are formed near the surface. They are found in alluvial deposits, where they have been eroded from their source and deposited in riverbeds and on the ocean floor.

The process of formation needs to be better understood. Still, it is thought to occur over millions of years and requires a combination of intense pressure and high temperatures. As a result, they can be found in various rock formations, including kimberlite pipes and lamproite rocks.

Etymology of Diamond

The word “diamond” comes from the Greek word “adamas,” which means “unbreakable” or “invincible.” This name reflects the exceptional hardness and durability of diamonds, which have long been considered one of the world’s most valuable and prized gems.

Their use in jewelry can be traced back to ancient India, where they were used in religious ceremonies and as talismans to ward off evil. The ancient Greeks and Romans also valued these gems for their beauty and rarity. As a result, they were often set into gold and used to decorate the armor and weapons of warriors.

Over time, they became associated with wealth, power, and luxury. In addition, they became a symbol of love and commitment when used in engagement rings. As a result, these gems continue to be one of the most sought-after gems in the world, and their popularity shows no signs of fading.

Diamond Appearance

Diamonds are formed when carbon atoms bond with other elements inside the earth’s crust. This process creates a unique crystalline structure that gives them high dispersion, a distinct appearance, and a brilliant shine.

The appearance can range from pure and flawless to chipped and splintered. They can also be found in various shapes and sizes, from round to heart-shaped to square. The color, shape, and quality can vary significantly depending on the type of stone, the conditions under which it was mined, and other factors.

Diamonds come in many colors, including yellow, blue, pink, and dark red. Their different hues can be attributed to the various elements present in the earth’s crust from which they are formed. The unique combination of cut, color, clarity, and carat weight contributes to its overall appearance, and these factors are considered when determining the value of a piece.

Types of Diamond

There are several different types of diamonds, each with unique properties and characteristics. Some of the most common types include:

  1. Natural diamonds are formed deep within the earth and have not been artificially altered or treated in any way.
  2.  Synthetic diamonds are created in a laboratory setting using high pressure and high temperature (HPHT) or chemical vapor deposition (CVD) methods. Synthetic pieces have the same physical and chemical properties as natural ones but are much less expensive.
  3.  Treated diamonds are natural but have been altered or treated in some way to improve their appearance or quality. Treatment methods include irradiation, which changes the color, and fracture filling, which hides cracks or inclusions.
  4.  Type I: These are the ones that contain a relatively small amount of nitrogen impurities, which give them a yellow or brown color.
  5.  Type II: This type contains little or no nitrogen impurities and is usually colorless or near-colorless.
  6.  Fancy colors have a unique and intense colors, such as blue, green, yellow, pink, or red. Fancy color gems are extremely rare and highly valuable.
  7.  Industrial grade is for industrial use only. These are not of gem quality. These are usually brown, yellow, gray, green, or black and lack the clarity and brilliance of a gemstone.

Different types of diamonds have varying physical and chemical properties. As a result, they can be used in various jewelry applications, from engagement rings to bracelets and necklaces. 

Grading System Of Diamonds

The grading system refers to evaluating the quality based on several factors known as the “Four Cs”: Carat Weight, Cut, Clarity, and Color. Professional gemologists use this system to determine the value and quality to help consumers make informed decisions when purchasing jewelry. GIA [Gemological Institute of America], an institute dedicated to education and research in gemology] is responsible for developing the four C’s of evaluating Diamond quality and also provides identification and grading for gemstones. Here is How GIA grades diamonds.

  1. Carat weight: This refers to the size and is measured in carats. One carat is equal to 200 milligrams, or 0.2 grams.
  2.  Cut: The cut refers to the angles and proportions and is a major factor in determining sparkle and brilliance. A well-cut piece will have the optimal combination of depth, table size, and angles to maximize the reflection and refraction of light.
  3.  Clarity: Clarity refers to the presence or absence of internal or external inclusions or blemishes. The clarity is rated on a scale that ranges from “included” (I1) to “flawless” (FL).
  4.  Color: The color is rated on a scale that ranges from “D” (no hue) to “Z” (light yellow or brown hue). A piece that is rated “D” is considered to be completely colorless. In contrast, a sample rated “Z” has a noticeable yellow or brown tint.

The combination of these Four Cs determines overall quality and value. The grading system is an international standard. Professional gemologists use a standardized set of criteria to evaluate the overall rating. This helps to ensure that diamonds are consistently and accurately assessed and that consumers clearly understand the quality when purchasing.

Diamond Value and Price

Various factors determine the value and price of a diamond, and the 4 Cs are the most important factors to consider when evaluating its worth.

  1. Carat weight: The carat weight refers to its size and is the unit of measurement used to weigh. The larger the piece, the higher its carat weight and value.
  2.  Cut: A cut refers to how it has been cut and polished to enhance its brilliance, fire, and overall beauty. A well-cut piece will have a higher value than a poorly-cut piece.
  3.  Clarity: Clarity is graded on a scale that ranges from included to flawless. Flawless pieces are extremely rare and highly valuable.
  4.  Color: While a pure piece is thought to be colorless, it can come in various colors, including yellow, pink, blue, green, and black. Colorless pieces are highly prized, and their value increases as the color become more intense.

In addition to the 4 Cs, other factors that can affect the value and price include the rarity, demand, origin, and reputation of the seller. It’s also important to consider the overall quality, as well as its cut, symmetry, and polish.

When buying, it’s important to research. First, choose a reputable jeweler who can provide you with a certificate of authenticity and a detailed description of the quality and value. 

How Can You Tell if Diamond Is Real?

Determining the authenticity of a diamond can be challenging, as synthetic and simulants have become increasingly sophisticated and difficult to distinguish from real ones. However, there are several tests that you can use to determine if a sample is real or not.

  1. Visual Inspection: A trained gemologist can determine if a piece is real or not based on its physical appearance, including its cut, clarity, color, and overall quality.
  2.  The Fog Test involves breathing on the sample and observing how it reacts to the fog. If the fog quickly dissipates, it is likely real. It may be a simulant if the fog lingers for a few seconds.
  3.  The UV Light Test: A real piece will emit a blue glow when exposed to ultraviolet (UV) light, while most simulants will not.
  4.  The Thermal Conductivity Test: These gems are excellent heat conductors, which will transfer heat quickly from one point to another. A real sample will quickly dissipate heat when you touch it, while simulants will not.
  5.  The Loupe Test: A jeweler’s loupe is a small magnifying glass that can inspect a piece for inclusions, blemishes, and other characteristics of a real sample.

International standards like the 4Cs have been established by organizations such as the Gemological Institute of America (GIA) and the American Gem Society to determine the authenticity and quality of diamonds. These organizations use rigorous testing methods, including X-ray spectroscopy and microscopic examination, to determine its characteristics and properties and issue certificates of authenticity.

While several tests can determine if a sample is real, it’s always best to work with a knowledgeable and experienced gemologist who can help you authenticate the piece and provide you with a certificate of authenticity.
