What is a Diamond?

Diamonds are captivating gemstones that have fascinated humans for centuries. Formed over a billion years ago, deep within the Earth's mantle, diamonds are composed of carbon atoms arranged in a crystalline structure. Under intense heat and pressure, carbon atoms bond together tightly to create the hardest naturally occurring substance known to man: the diamond.

For millions of years, diamonds remained hidden beneath the Earth's surface until volcanic eruptions propelled them upward in magma. This geological journey brought diamonds closer to the Earth's crust, where they could eventually be discovered by humans. The earliest recorded discovery of diamonds dates back to the 4th century BC in India, where they were treasured for their rarity and beauty.

Throughout history, diamonds have symbolized wealth, power, and everlasting love. Their brilliance and sparkle have made them a coveted choice for jewelry, from engagement rings to heirloom pieces. Beyond their aesthetic appeal, diamonds have also held cultural significance, representing purity, strength, and resilience.

Types of Diamonds

Natural Diamonds

Natural diamonds form deep within the Earth under extreme conditions of heat and pressure. They are comprised of nearly 99.95% carbon, with the other 0.05% reflecting trace elements that aren't part of their essential chemistry — making diamond the only gemstone constructed of a single element. They are the hardest naturally occurring material found on Earth and one of the most sought-after.

Lab Diamonds

Lab diamonds are optically, chemically, and physically the same as natural diamonds. In other words, they look, feel, and are identical. Their difference lies only in their origins — natural diamonds form within the Earth, and lab diamonds are grown by professionals with specialized equipment. Another difference relates to cost; as lab-grown diamonds are less rare than natural diamonds, they often come at a much more accessible price.

4 C's of Diamonds

Discover the 4 C's of diamonds: cut, color, clarity, and carat weight. These essential factors determine a diamond's quality and value. Understanding the 4 C's empowers you to make informed decisions when selecting the perfect lab-grown diamond for your jewelry piece.


In the world of diamonds, the "Cut" is a critical factor that directly impacts a diamond's beauty and overall appeal. It refers to the proportions, symmetry, and polish of a diamond, as well as the arrangement and quality of its facets. A well-cut diamond will exhibit exceptional brilliance, sparkle, and fire, captivating the eye with its radiance.

Diamond cuts are graded on a scale ranging from Excellent to Poor, with each grade reflecting the quality of the diamond's cut. Diamonds with an Excellent cut are meticulously crafted to maximize light performance, while those with a Poor cut may lack brilliance and appear dull.


Color in diamonds refers to the presence or absence of color in a stone. The Gemological Institute of America (GIA) grades diamond color on a scale from D to Z, with D being completely colorless and Z exhibiting noticeable color.

The less color a diamond has, the higher its value. However, some diamonds fall outside this range and are classified as "fancy colored," exhibiting hues like yellow, pink, or blue. Understanding diamond color is crucial when selecting a stone, as it greatly influences its appearance and value.

Clarity in diamonds refers to the presence or absence of internal characteristics, known as inclusions, and external features, known as blemishes. These imperfections affect a diamond's brilliance and transparency.

The clarity scale, established by the Gemological Institute of America (GIA), ranges from Internally Flawless (IF), meaning no internal flaws, to Included (I), where inclusions are visible to the naked eye. Understanding a diamond's clarity grade helps determine its overall quality and value.


In the world of diamonds, carat is a crucial metric, denoting the weight of the gemstone rather than its physical size. One carat equals 200 milligrams, about the weight of a standard paperclip. While carat weight influences a diamond's price, it's essential to consider other factors like cut, color, and clarity to assess its overall value and appearance. Understanding the significance of carat weight empowers you to make informed decisions when selecting the perfect diamond for your jewelry piece, ensuring it aligns with your preferences, style, and budget.

Diamond Shape

Shape denotes the external appearance of a diamond's outline and is separate from the cut, which pertains to the diamond's internal facet arrangement. While the round shape remains the most popular choice, there is a wide variety of other shapes, known as "fancy shapes," each offering its own unique aesthetic appeal.

From the classic elegance of the emerald and marquise shapes to the timeless beauty of the oval and pear shapes, there is a shape to suit every style and preference. Understanding the characteristics and visual impact of different diamond shapes can help you make an informed decision when selecting the perfect lab-grown diamond for your jewelry piece.

Diamond Hardness

Diamond is renowned as the hardest naturally occurring mineral on Earth. With a remarkable hardness ranking of 10 on the Mohs scale, a system devised in 1822 to gauge mineral hardness, diamonds stand unrivaled in their durability. This exceptional hardness attribute denotes the diamond's unparalleled resistance to scratching, a feat that only a diamond itself can accomplish.

This inherent robustness makes diamonds exceptionally well-suited for everyday wear, rendering them an ideal choice for various jewelry pieces, including engagement rings. Their enduring strength ensures that diamonds maintain their brilliance and integrity over time, withstanding the rigors of daily use without succumbing to wear and tear.

Whether adorning a pendant, bracelet, or ring, diamonds imbue jewelry with an enduring allure that captivates hearts and enhances elegance. As a testament to their enduring appeal, diamonds continue to symbolize everlasting love and timeless sophistication, making them a cherished choice for commemorating life's most precious moments.

Diamond Fluorescence

Diamond fluorescence is a fascinating phenomenon that describes how a diamond reacts when exposed to ultraviolet (UV) light. This reaction is graded based on the intensity of the diamond's response to long-wave UV, a component of natural daylight. Under UV light, diamonds may exhibit a faint blue or yellow glow, known as fluorescence. However, it's important to note that fluorescence typically has no discernible impact on the diamond's appearance under regular lighting conditions. Additionally, it does not compromise the structural integrity or quality of the stone in any way.

While some individuals may have concerns about fluorescence affecting the beauty or value of a diamond, the reality is that its presence or absence is often a matter of personal preference. In fact, diamonds with fluorescence can offer unique characteristics and may even appear to have enhanced color in certain lighting environments.

Ultimately, understanding diamond fluorescence empowers consumers to make informed choices when selecting their desired diamond jewelry. By learning about this natural phenomenon, individuals can appreciate the intricacies of diamonds and confidently choose the perfect stone that aligns with their preferences and aesthetic tastes.

Diamond Price

The price of diamonds is influenced by various factors, including their rarity and quality. Diamonds that exhibit superior characteristics in terms of cut, color, clarity, and carat weight are considered rarer and consequently command higher prices in the market. For instance, diamonds with excellent cut grades, exceptional color grades such as D or E, and high clarity ratings are typically more sought after and valued for their rarity and beauty.

Carat weight also plays a significant role in determining diamond prices. Larger diamonds are inherently rarer and thus carry a premium compared to smaller stones of similar quality. Additionally, the overall scarcity of certain diamond shapes or sizes can influence their market value.

In the case of lab-grown diamonds, their pricing structure differs from that of natural diamonds. While lab-grown diamonds possess identical physical and chemical properties to natural diamonds, they are typically priced lower due to their controlled manufacturing process and increased availability. Lab-grown diamonds offer an ethical and sustainable alternative to mined diamonds while providing excellent value for consumers.
