What Are Lab Grown Diamonds?
Lab grown diamonds are real diamonds created in controlled laboratory environments rather than mined from the earth. They have the same physical, chemical, and optical properties as natural diamonds.
These diamonds are made using advanced technological processes that replicate the natural conditions under which diamonds form. This process means that lab grown diamonds are not simulants like cubic zirconia or moissanite - they are genuine diamonds.
How Are Lab Grown Diamonds Made?
There are two main methods used to create lab grown diamonds:
1. HPHT (High Pressure High Temperature)
This method replicates the Earth’s natural diamond-forming conditions using extreme pressure and heat.
2. CVD (Chemical Vapour Deposition)
A diamond seed is placed in a carbon-rich gas chamber, where carbon atoms gradually build up layer by layer.
Both methods produce high-quality diamonds that are virtually identical to mined diamonds.
Lab Grown Diamonds vs Mined Diamonds
Appearance
Both types look identical to the naked eye and even under standard jeweller tools.
Composition
Both are made of pure carbon in a crystal structure.
Durability
Both score 10 on the Mohs hardness scale, making them extremely durable.
Price
Lab grown diamonds are typically 30%-70% more affordable than mined diamonds.
Benefits of Lab Grown Diamonds
1. Sustainable Choice
They reduce the need for large-scale mining operations.
2. Better Value for Money
You can often get a larger or higher quality diamond for the same budget.
3. High Quality and Purity
They often have fewer inclusions due to controlled growth conditions.
Are Lab Grown Diamonds Real Diamonds?
Yes. Lab grown diamonds are chemically and structurally identical to mined diamonds. Even professional gemological tools require advanced testing to distinguish between them. Major gemological institutes such as IGI (International Gemological Institute) and GIA (Gemological Institute of America) certify lab grown diamonds.
Are Lab Grown Diamonds Worth It?
For many buyers, lab grown diamonds are an excellent choice due to their affordability, ethical sourcing, and identical appearance to mined diamonds. They are especially popular among modern couples seeking sustainable luxury.
Common Myths About Lab Grown Diamonds
Myth 1: They are fake diamonds
False - they are real diamonds.
Myth 2: They don’t last as long
False - they are just as durable as mined diamonds.
Myth 3: They have no resale value
Partially true - resale markets are still developing, but value retention varies by market conditions.
Popular Uses of Lab Grown Diamonds
Lab grown diamonds are beautifully versatile, finding their way into some of the most cherished pieces of jewellery. They are often chosen to bring brilliance and meaning to engagement rings, symbolise everlasting love in eternity rings, add a touch of effortless elegance to earrings, and create timeless pendants that sit close to the heart.
