When buying diamonds, the choice between lab grown and natural is getting more and more important for consumers.
Knowing each other’s differences, benefits, and drawbacks will help you make a decision that aligns with your values, budget, and style.
Both lab grown and natural diamonds have their own sparkle and charm, and for different reasons.
This guide will get into the nitty gritty of lab grown vs natural diamonds so you can choose the right diamond for you.
Lab Grown Diamond vs Natural Diamond
What is a Lab Grown Diamond?
Lab-grown diamonds, also known as synthetic or man-made diamonds, are grown in a controlled laboratory environment using advanced technology like Chemical Vapor Deposition (CVD) and High-Pressure, High-Temperature (HPHT).
They have the same chemical, physical, and optical properties as natural diamonds and are virtually indistinguishable to the naked eye.
Chemical Vapor Deposition (CVD)
The CVD process involves placing a diamond seed in a chamber filled with carbon-rich gases.
These gases are then ionized to break down the molecules and carbon atoms deposit onto the seed and form a diamond crystal.
This method allows for the growth of high-quality diamonds with fewer inclusions and better color.
High-Pressure High Temperature (HPHT)
HPHT mimics the natural diamond-forming environment by applying high pressure and high temperature to carbon.
This can be used to grow diamonds from scratch or to upgrade existing diamonds, such as turning brown to near colorless.
What is a Natural Diamond?
Natural diamonds are formed over millions of years under extreme heat and pressure deep in the earth.
They are mined, cut, and polished to get to their final form.
Each natural diamond is unique, with its own set of inclusions and characteristics.
The rarity and natural process of these diamonds make them valuable and desirable.
Chemical Composition and Physical Properties
Lab grown and natural diamonds have the same chemical composition, with carbon atoms arranged in a crystal lattice structure.
They have the same hardness, refractive index, and brilliance, and they are equal in durability and beauty.
Creation Process
- Lab Grown Diamonds: Created in weeks to months in a lab using CVD or HPHT methods. These methods replicate the natural process of diamond formation but in a much shorter time frame.
- Natural Diamonds: Formed over billions of years under the earth’s crust through natural geological processes.
Visual Differences
To the naked eye, there is no visible difference between lab grown and natural diamonds.
Advanced gemological equipment is needed to see minute differences, like the presence of nitrogen in natural diamonds and the absence of it in lab-grown ones.
However, some natural diamonds may have unique inclusions that can be fingerprinted, which differentiates them from lab-grown ones.
Cost and Value
- Lab Grown Diamonds: Generally 30-50% less expensive than natural diamonds of comparable quality. For example, a 1-carat lab-grown diamond can range from $1,000 to $3,000, depending on its cut, color, and clarity. This affordability allows consumers to purchase larger or higher-quality stones within the same budget.
- Natural Diamonds: Typically hold their value better over time due to their rarity and the extensive processes involved in their formation and extraction. For a 1-carat natural diamond, prices can range from $3,000 to $10,000, with higher investment value making them a preferred choice for those looking to retain value over the long term.
Ethical and Environmental Considerations
- Lab-Grown Diamonds: These are more ethical as they don’t involve mining, which has environmental and social problems. Mining destroys habitats, pollutes water, and moves communities. CVD and HPHT process energy consumption are notable. However, efforts are being made to reduce the carbon footprint of lab-grown diamonds by using renewable energy. To make lab-grown diamonds even more eco-friendly, minimize greenhouse gas emissions and fossil fuel use.
- Natural Diamonds: The Kimberley Process has reduced conflict diamonds or “blood diamonds,” which are mined in war zones and sold to fund wars against governments. While it’s improved, it’s not foolproof. Mining has environmental and moral issues. Extraction deforests, erodes soil, and contaminates water sources. Labor conditions in some mining areas are poor and unsafe, and workers are exploited.
Pros and Cons – Lab Grown Diamond vs Natural Diamond
Lab Grown Diamonds
Pros
- Cheaper: 30-50% less than natural diamonds, so you can buy larger or better.
- Environmental: No destructive mining.
- Ethical: Social and ethical issues of mining.
- Identical: Indistinguishable to the naked eye and chemical composition.
Cons
- Resale value: Lab-grown diamonds don’t hold value like natural diamonds.
- Energy consumption: CVD and HPHT process energy is high but being reduced with renewable energy.
Natural Diamonds
Pros
- Value: Natural diamonds are more valuable and traditional.
- Traditional: People prefer the natural process and history of natural diamonds.
- Unique natural process: Each natural diamond has its own inclusions and characteristics.
Cons
- Expensive: Natural diamonds are costly due to their rarity and mining and refining process.
- Ethical and environmental issues: Mining destroys the environment and bad labor in some areas.
Certification and Grading
Both lab grown and natural diamonds can be certified by gemological laboratories like GIA.
Certification is detailed information on the 4Cs: Carat, Color, Clarity, and Cut.
Certification is the quality and authenticity of the diamond, whether lab-grown or natural.
Certification also helps with value, ethics, and the quality of the diamond.
Certified diamonds are graded on the same scale so consumers can compare and buy wisely.
Conclusion
Ultimately, it comes down to personal values, budget, and priorities.
Both are stunning and durable, so you’ll have a piece of jewelry to treasure forever.
Lab grown diamonds are for those looking for affordability, ethics, and environmental awareness.
They’re a cost-effective option without compromising on quality or looks.
Eco-friendly production and ethical sourcing make them a great option for environmentally and socially conscious consumers.
Natural diamonds are preferred for their history, unique natural formation, and higher long-term value retention.
The natural formation process gives each diamond its own personality and story, which adds to its emotional and sentimental value.
Natural diamonds are also a traditional symbol of luxury and prestige, often appreciated for their rarity and the time it takes to create them.
By understanding the difference between lab-grown diamond vs natural diamonds, you can confidently choose the one that best fits your personal preferences and lifestyle.
Frequently Asked Questions
Are lab-grown diamonds real diamonds?
Yes, lab grown diamonds are real diamonds.
They have the same chemical, physical, and optical properties as natural diamonds.
The only difference is the origin.
Lab grown diamonds are grown in a lab; natural diamonds are grown beneath the earth for millions of years.
Can you tell the difference between lab-grown and natural diamonds?
To the naked eye, lab grown and natural diamonds are indistinguishable.
You need advanced gemological equipment to detect the difference.
Lab-grown diamonds may not have all the inclusions or characteristics of natural diamonds, but visually, they are the same.
What is the cost difference between lab-grown and natural diamonds?
Lab grown diamonds are 30-50% less expensive than natural diamonds of the same quality.
For example, a one-carat lab-grown diamond can range from $1,000 to $3,000, and a one-carat natural diamond can range from $3,000 to $10,000.
Are lab-grown diamonds ethical and environmentally friendly?
Lab-grown diamonds are more ethical as they don’t involve mining, which can lead to environmental degradation and poor labor practices.
However, the energy-intensive processes (CVD and HPHT) do consume a lot of energy, though efforts are being made to use renewable sources to offset this.
