What are lab-grown diamonds? This question is becoming increasingly relevant as more people consider sustainable and ethical alternatives to mined diamonds.
Laboratory-grown diamonds, also known as synthetic or cultured diamonds, have the same physical and chemical properties as natural diamonds but are grown in a lab.
This article will cover what lab-grown diamonds are, their benefits, and what to consider when buying them.
What Are Diamonds?
Diamonds are crystalline carbon formed deep in the earth over billions of years under extreme heat and pressure.
This creates a crystal lattice structure, which gives diamonds their properties. Volcanic activity brings these diamonds to the earth’s surface, where they can be mined.
Known for their incredible hardness, diamonds score 10 on the Mohs scale and are the hardest natural substance.
This hardness makes them durable and useful for many things, from jewelry to industrial applications.
Diamonds brilliance is their high refractive index and dispersion of light which gives them their sparkle.
Diamonds are graded on the 4Cs: cut, color, clarity, and carat weight. Cut affects the diamond’s brilliance, and the color goes from colorless (D) to light yellow or brown (Z).
Clarity measures the presence of internal and external imperfections, and carat weight is the size of the diamond.
What Are Lab Grown Diamonds?
Laboratory-grown diamonds are diamonds grown in specialized laboratories using advanced technology that replicates the natural conditions under which diamonds form on the earth.
They have the same crystal structure, chemical composition, and physical properties as natural diamonds, so they are virtually indistinguishable from the naked eye.
Lab-grown diamonds involve replicating the extreme heat and pressure found deep in the earth’s mantle or using chemical processes to build up diamond layers atom by atom.
Lab-grown diamonds can be grown in various sizes, shapes, and colors, so there are many options for the consumer.
They are graded the same as natural diamonds: the 4Cs, and they can be applied to many uses.
How Are Lab Diamonds Made?
The Lab-grown diamonds are produced in two ways:
High-pressure High Temperature (HPHT)
This method replicates the way diamonds are formed naturally by using high pressure and high temperature to convert carbon into diamonds.
HPHT diamonds are made by placing a small diamond seed in a chamber with carbon and subjecting it to intense heat and pressure.
Around the seed, the carbon crystallizes to form a diamond.
Chemical Vapor Deposition (CVD)
This method involves breaking down carbon-containing gas molecules to deposit carbon atoms onto a diamond seed and building up the diamond layer by layer.
With the CVD process, a diamond seed is placed in a vacuum chamber filled with a carbon rich gas mixture.
The gas is then heated and the carbon atoms separate and settle on the seed to form a diamond over time.
Why Choose Lab Grown Diamonds?
Lab-grown diamonds are popular for several reasons. They are often more affordable than natural diamonds and free from the ethical and environmental issues associated with diamond mining.
Plus, they are high quality and can be grown in any size and shape.
The lab-grown diamond market is growing fast. The global market was valued at $19.3 billion in 2020 and is projected to reach $49.9 billion by 2030, growing at a CAGR of 9.4% from 2021 to 2030 (Source: Allied Market Research).
This growth is driven by consumer demand for sustainable and ethical alternatives to mined diamonds.
Lab-Grown Diamond Benefits
Cost
Lab-grown diamonds are relatively cheaper than natural diamonds if they are of the same size and quality.
For the same amount of money, you can purchase a stone of a bigger or better quality.
We will compare the prices later, but logically, the main benefit is the cost, making it possible for those who want the most of their money to get them.
Quality and Size
Cultured diamonds are as good as natural diamonds and are produced with the same qualities.
They can be prepared in different sizes and shapes and may also be of different colors.
Also, the synthetic diamonds are very much alike the natural diamonds and even the best of the experts would not be able to differentiate between the two without the use of certain equipment.
Environmental Impact
Synthetic diamonds are more environmentally friendly than natural mine diamonds, as we said before.
Mining diamonds is disastrous for the land, is energy-consuming, and pollutes water sources.
The process of producing lab-grown diamonds does not use energy and is not a threat to the environment.
Ethical Concerns
The ethical issues related to the mining of diamonds include human rights abuses and the compounding of conflicts.
Lab-grown diamonds do not have any connection with conflicts meaning that your purchase of these diamonds will not contribute to the promotion of such vices.
Cost Comparison with Natural Diamonds
One of the most significant advantages of laboratory diamonds is, of course, their cost-effectiveness compared to natural diamonds.
Lab-grown diamonds typically cost 20-40% less than their natural counterparts.
For example, a one-carat lab-grown diamond might cost around $2,500, whereas a similar natural diamond could cost $4,000 or more.
This price difference allows buyers to save money or purchase a larger or higher-quality diamond for the same budget.
Myths and Misconceptions About Lab-Grown Diamonds
There are several myths and misconceptions surrounding lab-grown diamonds that need to be addressed:
1. Lab-Grown Diamonds Are Fake.
Lab-grown diamonds are real diamonds with the same physical and chemical properties as natural diamonds. They are not to be confused with diamond simulants like cubic zirconia or moissanite.
2. Lab-Grown Diamonds Are Not as Durable.
Lab-grown diamonds are just as durable as natural diamonds. They have the same hardness (10 on the Mohs scale) and can withstand everyday wear and tear.
3. Lab-Grown Diamonds Have No Resale Value.
While lab-grown diamonds may not retain their value as well as natural diamonds, they still hold significant value, especially considering their ethical and environmental benefits.
The market for lab-grown diamonds is also growing, which may enhance their resale value over time.
Buying Tips to Avoid Fake Lab-Grown Diamonds
- Purchase from Reputable Sellers: Always buy from trusted and reputable jewelers who provide certificates (GIA) of authenticity and have positive reviews. Researching the seller and reading customer feedback can help ensure you are dealing with a trustworthy source.
- Request Detailed Information: Ask for detailed information about the gemstone, including its origin, grading, and any treatments it may have undergone. A reputable seller should be transparent and willing to provide all necessary details.
- Use a Moissanite Tester: Before making a purchase, ask the seller to use a Moissanite tester to confirm the stone’s authenticity. This quick test can save you from potential fraud.
- Seek Professional Advice: If in doubt, consult a professional jeweler for an appraisal before finalizing your purchase. An expert opinion can provide assurance and identify any potential issues with the stone.
- Avoid Deals that Seem Too Good to Be True: Extremely low prices can be a red flag for counterfeit stones. Ensure the price aligns with the market value for genuine lab-grown diamonds. Comparing prices from various reputable sources can help you gauge a fair market price.
