Lab Grown Diamond Guide - Natural vs. Lab Diamonds
Diamonds have long been a symbol of status and luxury. With the advancement of technology, lab-grown diamonds have become more prominent in the jewelry market. Both lab-grown and natural diamonds have their own unique characteristics it’s important to understand the differences between them.
This article will explore various aspects of man-made diamonds and how they compare to their natural counterparts, moissanites, and cubic zirconia. We will also examine their benefits, color availability, and grading information.
Where Do Lab-Grown Diamonds Come From?
Man-made diamonds are one of the most cherished diamonds created in a highly controlled laboratory environment using advanced technological processes. These processes replicate the natural conditions in which diamonds are formed. Two methods are primarily used to create lab-grown diamonds:
1. High-Pressure High Temperature (HPHT):
In this method, carbon is exposed to high pressure and high temperature to replicate conditions similar to those found in the Earth’s mantle. Usually, a tiny diamond is placed in the carbon as a seed, and under intense heat and pressure, the carbon crystallizes around the seed to form a diamond.
2. Chemical Vapor Deposition (CVD):
This method involves placing a diamond seed inside a vacuum chamber filled with carbon-rich gases. These gases are then heated, causing carbon atoms to separate and form layers on the diamond seed, gradually creating a diamond crystal.
Both methods produce diamonds that are chemically, physically, and optically similar to natural diamonds.
Why Choose Lab-Grown Diamonds?
These man-made diamonds are slowly becoming popular due to several factors:
1. Cost Efficiency: Engineered diamonds typically cost 30-40% less than natural diamonds. This cost advantage is due to the controlled manufacturing process, which allows for consistently producing high-quality diamonds.
2. Sustainability: The environmental impact of lab-grown diamonds is considerably lower than that of natural diamond mining. They eliminate the need for large-scale mining, which often negatively impacts ecosystems and local communities.
3. Ethical Sourcing: Compared to natural diamonds, lab-grown diamonds are free from ethical concerns. Consumers who prioritize ethical sourcing often choose these diamonds.
4. Customization: The ability to produce diamonds in a lab setting offers greater flexibility in terms of size, shape, and color, making these diamonds a popular choice for custom jewelry designs.
Lab-Grown Diamonds vs. Natural Diamonds
When comparing engineered diamonds to natural diamonds, the following key aspects can be considered:
1. Origin: Natural diamonds take millions of years to form and are formed deep within the Earth’s mantle, whereas lab-grown diamonds can be created in a matter of weeks using advanced technology.
2. Chemical Composition: Both lab-grown and natural diamonds are composed of pure carbon and exhibit the same chemical structure, making them visually and physically identical.
3. Durability: Both types of diamonds rank 10 on the Mohs scale of hardness, which means they are highly durable and resistant to scratching.
4. Visual Differences: Lab-grown and natural diamonds both have the same sparkle, brilliance, and fire, so there are no visible differences to the naked eye.
5. Value: Natural diamonds tend to hold their value better than man-made diamonds due to their rarity and market demand. Lab-grown diamonds, while more affordable initially, may not retain their value to the same extent.
6. Environmental Impact: Lab-grown diamonds have a smaller carbon footprint than natural diamonds, which require extensive mining and resource extraction.
Lab-Grown Diamonds vs. Moissanites vs. Cubic Zirconia
Lab-grown diamonds, moissanite, and cubic zirconia are all popular choices in the jewelry market, but they are quite different in terms of composition, durability, and appearance.
1. Lab-Grown Diamonds:
- Composition: Composed of pure carbon, identical to natural diamonds.
- Hardness: 10 on the Mohs scale, making them the hardest gemstone.
- Appearance: Fabricated diamonds exhibit the same brilliance and fire as natural diamonds.
2. Moissanites:
- Composition: Composed of silicon carbide, a naturally occurring mineral.
- Hardness: 9.25 on the Mohs scale, making them durable but slightly softer than diamonds.
- Appearance: Moissanites exhibit more brilliance and fire than diamonds but may have a rainbow-like sparkle, making them appear different in some lighting conditions.
3. Cubic Zirconia:
- Composition: A synthetic material made from zirconium dioxide.
- Hardness: 8-8.5 on the Mohs scale, making it more prone to scratching over time than diamonds.
- Appearance: Cubic zirconia has less brilliance and fire than diamonds and can appear cloudy over time.
When comparing lab-grown diamonds to moissanite and cubic zirconia, lab-grown diamonds offer the closest visual and physical properties to natural diamonds. Moissanites are a popular alternative due to their affordability and durability, but they are not identical to diamonds. Cubic zirconia is the most affordable option but lacks the same brilliance and longevity.
How Can Natural and Laboratory-Grown Diamonds Be Distinguished from One Another?
It is nearly impossible to distinguish between a natural and lab-grown diamond with the naked eye. However, there are some scientific methods used by gemologists to differentiate between the two:
1. Inclusions and Impurities: Natural diamonds often contain small inclusions or impurities, such as tiny bits of other minerals trapped during their formation. Fabricated diamonds may have fewer inclusions or exhibit different patterns of inclusions, which can be detected under magnification.
2. Growth Patterns: Natural diamonds show distinct growth patterns due to their long formation process. On the other hand, lab-grown diamonds can have unique growth patterns related to the technology used in their creation, which can be identified using specialized equipment.
3. Fluorescence: Some lab-grown diamonds exhibit different types of fluorescence than natural diamonds. This can be detected under ultraviolet (UV) light.
4. Laser Inscription: Many fabricated diamonds have a laser inscription on the girdle that indicates their origin. Such inscriptions are invisible to the naked eye but can be seen under magnification.
Gemological institutes, such as the GIA (Gemological Institute of America), use sophisticated equipment to accurately identify whether a diamond is lab-grown or natural.
