Understanding Diamonds from Every Angle
Discover the Science Behind Diamonds: In-depth Details You Need to Know.
See what you can going to be exploring about Diamonds: Nature's Marvel
More than a billion years ago, deep within the Earth, carbon atoms joined together under intense heat and pressure, forming what we now know as diamondsāthe toughest natural mineral on Earth.
After spending millions of years hidden deep underground, diamonds finally made their way to the surface through volcanic eruptions. The first discovery of diamonds dates back to ancient India in the 4th Century Before Christ. Since then, these dazzling gems have captured the hearts of people worldwide, remaining one of the most sought-after treasures.
At AARA, we cherish the beauty and wonder of diamonds. Join us in celebrating these extraordinary gems and their timeless allure.
Understanding Lab-Grown Diamonds
Lab-grown diamonds also referred to as man-made or cultured diamonds are created in carefully controlled laboratory settings. These diamonds are formed using cutting-edge technology that replicates the natural conditions in which diamonds develop beneath the Earth's surface.
Instead of being mined from the earth, lab-grown diamonds are produced by arranging carbon atoms in the same crystal structure as natural diamonds. This process results in diamonds that possess identical optical and chemical properties to those found in nature. In essence, lab-grown diamonds offer a sustainable and ethical alternative to traditional mined diamonds.
The Production Process of Lab-Grown Diamonds
Lab-grown diamonds originate from minuscule carbon seeds extracted from existing diamonds. Scientists employ advanced techniques, either through extreme pressure and heat or a specialized deposition method known as chemical vapor deposition (CVD), to replicate the natural diamond formation process.
Over a period of six to ten weeks, a rough diamond is cultivated. Subsequently, it undergoes meticulous cutting, polishing, and setting to become a finished piece of lab-grown diamond jewelry, such as earrings, necklaces, or bracelets.
There are two primary methodologies for creating lab-grown diamonds:
1. High Pressure High Temperature (HPHT): This method emulates the natural conditions found deep within the Earth's mantle. A sizable machine subjects a specified amount of carbon material to crushing pressures exceeding 870,000 pounds per square inch, along with extreme temperatures ranging from 1300 to 1600 degrees Celsius.
2. Chemical Vapor Deposition (CVD): In CVD, a seed diamond is placed within a small vacuum chamber filled with heated hydrogen and carbon-containing gases. At a particular temperature, these gas molecules disintegrate, resulting in layers of crystallized carbon forming around the seed, gradually enlarging the diamond. Some lab-grown diamonds produced via CVD may undergo additional pressure and heat treatment post-growth.
Distinguishing between natural diamonds and lab-grown diamonds cultivated through HPHT or CVD methods is virtually impossible for the naked eye. Only through the analysis of identifying markers caused by the growth conditions can scientists differentiate between them.
Comparing Lab-Grown Diamonds to Natural Diamonds
To the naked eye, distinguishing between a lab-grown and a natural diamond is nearly impossibleāthey share identical appearances. The sole discernible contrast lies in their origins: one originates from deep within the Earth, while the other is cultivated in a controlled laboratory environment.
Our lab-grown diamonds boast identical physical, chemical, and optical properties as their natural counterparts, showcasing the same brilliance, sparkle, and fire. While lab-created diamonds may contain trace elements that differ from natural diamonds, these variations have no impact on the diamond's visual appearance. The differentiation between lab-grown and natural diamonds necessitates specialized equipment and testing procedures.

How Lab-Grown Diamonds Are Certified and Graded
Lab-grown diamonds undergo the same rigorous certification process as natural diamonds:
1. Certification Process: Qualified gemologists at esteemed institutions like the Gemological Institute of America (GIA) and the International Gemological Institute (IGI) meticulously evaluate each diamond's 4 C's (cut, color, clarity, and carat) to provide comprehensive reports, usually IGI certified.
Understanding the 4 C's of Diamonds
Gain insights into diamond quality by exploring the 4 C's:
1. Cut: Refers to the proportion and arrangement of facets determining a diamond's brilliance. Grades range from Excellent to Poor.
2. Color: Describes the absence of color within a diamond, rated from D (colorless) to Z. Diamonds beyond this range are considered 'fancy colored.'
3. Clarity: Indicates the presence of internal inclusions and surface blemishes, graded from Internally Flawless to Included.
4. Carat: Measures a diamond's weight, not its size, with one carat roughly equaling the weight of a paperclip.
Digital Certification for Sustainability
We prioritize sustainability by digitally delivering certifications with your purchase:

Diamond Shape
Discover the beauty of diamond shapes at AARA:
1. Round: The most popular shape, known for its timeless elegance.
2. Fancy Shapes: Includes emerald, marquise, oval, and more, offering unique and distinctive outlines.
Diamond Hardness
Explore the durability of diamonds:
1. Hardest Mineral: Diamond ranks at the highest level (10) on the Mohs scale, signifying unparalleled hardness.
2. Resistance to Scratching: With unmatched scratch resistance, diamonds are ideal for everyday wear and are perfect for center stones in jewelry and engagement rings.
Diamond Fluorescence
Understand the unique phenomenon of diamond fluorescence:
1. UV Reaction: Fluorescence refers to a diamond's reaction to UV light, often emitting a blue or yellow glow.
2. Invisible Effect: While noticeable under UV light, fluorescence does not affect the appearance or structural integrity of the diamond under regular lighting.
Fluorescence is not a grading factor like the GIA 4Cs (color, clarity, cut, and carat weight), but it is an identifying characteristic. GIA Diamond Grading Reports and Diamond Dossiers describe a diamondās fluorescence by its intensity under long-wave UV light (None, Faint, Medium, Strong and Very Strong). If the fluorescence is Medium, Strong, or Very Strong, the color of the fluorescence will be noted.
Diamond Price
Explore the factors influencing diamond pricing:
1. Rarity and Quality: Diamonds with higher grades in cut, color, clarity, and carat weight are rarer and therefore more expensive.
2. Lab Grown Diamonds: Offered at a lower price point compared to natural diamonds, reflecting their availability and sourcing process.
Fun facts of diamonds
