What is a Man Made Diamond Called: Unveiling Synthetic Gemstones

Man Made Diamond

Man-made diamonds, also known as synthetic or lab-grown diamonds, are identical to natural diamonds in their chemical, physical, and optical properties. These diamonds are created in controlled laboratory environments using advanced technological processes that replicate the high-pressure, high-temperature conditions under which natural diamonds form within the Earth's mantle. The main distinction between the two lies in their origin—one is unearthed from geological processes while the other is crafted by human hands. 

As you explore the realm of man-made diamonds, you will come across terms such as "CVD diamonds" or "HPHT diamonds," which refer to the methodologies used to produce them—Chemical Vapor Deposition and High Pressure High Temperature, respectively. This innovation in diamond production offers you the same beauty and durability as mined diamonds, often at a more accessible price point and with fewer ethical and environmental concerns. Due to their growing popularity, man-made diamonds are becoming a favored choice for jewelry, particularly for those seeking a more sustainable option.

Understanding Man-Made Diamonds

When you hear about man-made diamonds, you're encountering the cutting-edge blend of technology and gemology. These stones rival their natural counterparts in beauty and durability.

Definition and Overview

Man-made diamonds, also referred to as synthetic or lab created diamonds, are real diamonds produced in a controlled environment as opposed to the natural geological processes. Unlike imitation gems, these created diamonds have the same physical, chemical, and optical properties as mined diamonds. The primary difference lies in their origin - man-made diamonds are cultivated in labs over weeks or months, whereas natural diamonds form over billions of years underground.

Types of Synthetic Diamonds

There are two main types of synthetic diamonds you should know about:

  1. High Pressure High Temperature (HPHT) - This method mimics the natural conditions that create diamonds underground, using immense pressure and heat to transform carbon into a diamond.
  2. Chemical Vapor Deposition (CVD) - CVD diamonds are grown from a hydrocarbon gas mixture, using technology that allows the carbon atoms in the gases to accumulate on a substrate, forming layers that develop into diamond crystals.

Both HPHT and CVD methods have advanced to a point where the synthetic diamonds they produce can be virtually indistinguishable from natural diamonds without professional analysis.

The Creation Process

Man-made diamonds are crafted in laboratories using advanced technological processes that mimic the conditions under which natural diamonds form. These controlled conditions allow for the transformation of carbon into stunning, crystal-clear diamonds that are optically, chemically, and physically akin to those mined from the Earth.

High Pressure High Temperature (HPHT) Method Machines

High Pressure High Temperature (HPHT)

The HPHT method replicates the natural diamond-growing environment by exposing carbon to high pressure and high temperature. A diamond seed is placed in carbon, typically in the form of graphite. The environment inside the HPHT machine is then set to conditions known for diamond formation: temperatures of about 1400-1600°C and pressures above 5 GPa. This process results in a crystallized diamond once the conditions are maintained for a sufficient period.

CVD method for lab grown diamonds

Chemical Vapor Deposition (CVD)

Alternatively, Chemical Vapor Deposition (CVD) involves a different approach to creating diamonds. In this process, you start with a thin slice of diamond seed, which is placed in a sealed chamber. The chamber is then filled with a carbon-rich gas, such as methane, and the gas is ionized into plasma using technology similar to that of microwaves or lasers. The ionization breaks down the molecular bonds in the gases, and pure carbon adheres to the diamond seed. The carbon atoms gradually build up in layers, forming a diamond. CVD operates at relatively lower temperatures compared to HPHT—about 700-1000°C—and does not require the same extreme pressures.

In your quest to understand diamonds, it's crucial to recognize that while both lab-grown and natural diamonds hold their own appeal, they share many similarities and yet differ in key aspects.

Physical and Optical Characteristics

Lab-grown and natural diamonds exhibit identical physical and optical properties to the naked eye; they both refract light spectacularly, creating that brilliance and fire which are so prized. The hardness of both diamond types is the same, each scoring a perfect 10 on the Mohs scale, making them the hardest known minerals on Earth. Your lab-grown diamond and a natural counterpart will both scratch anything else—and not get scratched in return.

Chemical and Structural Composition

Chemically, mined diamonds and their lab-grown analogues are made of the same building blocks: pure carbon, arranged in a crystal lattice structure that imparts both types of diamonds with their renowned durability. However, synthetic diamonds do not generally come with the same types of impurities or inclusions found in natural diamonds, which are remnants of their formation deep within the Earth. This difference under a microscope serves as a marker to differentiate between a diamond made by nature and one crafted in a lab.

Quality and Grading

In the realm of man-made diamonds, your understanding of quality and grading is essential. These lab-created gems are evaluated much like their natural counterparts, focusing on the Four Cs—clarity, color, cut, and carat weight—which directly influence their value and appeal.

The Four Cs

Clarity refers to the absence of inclusions and blemishes. Man-made diamonds, although created in controlled conditions, can exhibit such imperfections, similar to natural diamonds. Color in man-made diamonds ranges from colorless to various tints, which are graded on a scale from D (colorless) to Z (light color). Cut is about how well the diamond has been shaped from its rough form and includes aspects of proportion, symmetry, and polish, affecting the stone's brilliance. Carat weight simply measures a diamond's weight, with one carat being equivalent to 200 milligrams.

Grading Certifications

When you own a man-made diamond, ensure it comes with a grading report, also known as a certification. Renowned entities like the Gemological Institute of America (GIA) provide certifications outlining a diamond's attributes based on the Four Cs. This certification confirms the authenticity and quality of your man-made diamond, giving you confidence in your investment.
