Laboratory Grown Diamonds: Revolutionising the Jewellery Industry
Are you searching for a stunning diamond that is both ethical and affordable? Look no further than laboratory grown diamonds. These remarkable gems offer all the beauty and durability of natural diamonds, but with significant advantages in terms of cost, environmental impact, and ethical sourcing.
Many diamond shoppers face a common dilemma: how to find a high-quality, beautiful diamond without breaking the bank or compromising their values. Laboratory grown diamonds provide the perfect solution, offering identical physical and chemical properties to natural diamonds at a fraction of the cost.
In this comprehensive guide, we will explore everything you need to know about laboratory grown diamonds, from their creation process to their benefits and how to choose the perfect stone. By the end, you will be equipped with the knowledge to make an informed decision about your next diamond purchase.
What Are Laboratory Grown Diamonds?
Laboratory grown diamonds, also known as lab-created or synthetic diamonds, are real diamonds that are created in controlled laboratory environments rather than mined from the earth. Lab grown Diamonds are not to be confused with other stimulants like cubic zirconias or moissanites which are easily distinguishable from natural Diamonds.Lab grown diamonds have the same physical, chemical, and optical properties as natural diamonds, making them practically indistinguishable from their natural counterparts.
The concept of creating diamonds in a laboratory setting dates back to the 1950s when General Electric first successfully produced small industrial-grade diamonds. However, it wasn’t until recent years that technological advancements allowed for the creation of larger, gem-quality diamonds suitable for jewellery.
Key Facts About Laboratory Grown Diamonds:
They are chemically, physically, and optically identical to natural diamonds
Lab grown diamonds are graded using the same 4Cs criteria as natural diamonds: Cut, Colour, Clarity, and Carat weight
These diamonds are certified by the same gemological institutes that certify natural diamonds, such as the Gemological Institute of America (GIA) and the International Gemological Institute (IGI)
Lab grown diamonds are generally accepted to be more eco-friendly and ethically sourced than natural diamonds.
They typically cost a lot less than comparable natural diamonds. The larger the stone, the larger the saving with small lab grown diamomds working out to around half the price of the natural versions with larger stones costing thousands of pounds less.
The Creation Process: HPHT and CVD Methods
There are two primary methods used to create laboratory grown diamonds: High Pressure High Temperature (HPHT) and Chemical Vapour Deposition (CVD). Both processes aim to replicate the natural conditions under which diamonds form in the earth.
High Pressure High Temperature (HPHT)
The HPHT method mimics the high-pressure, high-temperature conditions found deep within the Earth’s mantle where natural diamonds form.
Process:
A small diamond seed is placed in a chamber with pure carbon.
The chamber is heated to about 1,500°C (2,732°F) and subjected to pressures of approximately 1.5 million pounds per square inch.
Under these extreme conditions, the carbon melts and begins to form a diamond crystal around the seed.
The process continues for several days to weeks, depending on the desired size of the diamond.
Chemical Vapour Deposition (CVD)
The CVD method is a more recent innovation that allows for greater control over the diamond’s growth and properties.
Process:
A thin slice of diamond seed is placed in a sealed chamber.
The chamber is filled with carbon-rich gas (usually methane) and heated to about 800°C (1,472°F).
Microwaves, lasers, or other energy sources are used to break down the gas molecules.
The carbon atoms from the broken-down gas adhere to the diamond seed, slowly building up the crystal structure.
This process continues for several weeks to produce a rough diamond.
Both methods produce high-quality diamonds suitable for jewellery. The choice between HPHT and CVD often depends on the specific characteristics desired in the final product.
Benefits of Choosing Lab Grown Diamonds
Laboratory grown diamonds offer numerous advantages over their natural counterparts, making them an increasingly popular choice among consumers.
1. Ethical Sourcing
One of the most significant benefits of lab grown diamonds is their ethical sourcing. Unlike natural diamonds, which have been associated with conflict and unethical mining practices, lab grown diamonds are created in controlled environments without the need for mining.
No risk of supporting conflict or “blood” diamonds
Guaranteed ethical sourcing and production
Transparent supply chain from creation to retail
2. Environmental Sustainability
Lab grown diamonds have a significantly lower environmental impact compared to mined diamonds.
Reduced carbon footprint
No land disruption or ecosystem damage from mining
Minimal water usage compared to diamond mining operations
3. Cost-Effectiveness
Perhaps one of the most appealing aspects of lab grown diamonds is their affordability.
Typically between 50% (small stones) & 80% (larger stones) less expensive than comparable natural diamonds
Allows consumers to purchase larger, higher-quality diamonds within their budget
More value for money in terms of size and quality
4. Consistent Quality
The controlled environment in which lab grown diamonds are created allows for more consistent quality and fewer inclusions.
Higher likelihood of finding higher grade diamonds in both colour & clarity
Consistent colour and clarity grades
Ability to create fancy coloured diamonds more easily and consistently
5. Technological Innovation
Choosing lab grown diamonds supports and encourages technological advancements in diamond production.
Contributes to the development of more efficient and sustainable diamond creation methods
Supports research that may have applications beyond the jewellery industry
