Our lab experts select the finest quality diamond seeds. It is most important to select seeds without any imperfections. The best seeds are carefully positioned on a metal disk to be placed inside the diamond-growing greenhouse.
The metal disk with the diamond seeds is placed inside a diamond growing reactor. Our labs use both processes - High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).
Over the next 10 to 12 weeks, the seeds go through various processes. A combination of gases, pressure and temperature create an environment that allows carbon atoms to break down and rain upon the seeds. As weeks go by, atom-by- atom, layer-by- layer, the seeds transform into rough diamonds.
These rough diamonds acquire the same chemical, physical and optical properties as mined diamonds, through both, the HPHT and CVD processes.
The rough diamonds are then cut and polished to exacting standards in our high tech factory. The expertise of our master cutters and lazer techniques ensure each diamond is carefully cut and polished to yield a beautiful and real cultivated diamond.
Our grown diamonds are ready to be set into jewelry pieces.
The time it takes to create a lab-grown diamond can vary greatly depending on the method used and the desired size and type of diamond.
There are two primary methods for creating diamonds grown in lab:
- High Pressure High Temperature (HPHT): It typically takes about a week to grow a diamond of average size suitable for jewelry However, smaller diamonds can form in as little as 2-3 days.
- Chemical Vapor Deposition (CVD): The process usually ranges from a few weeks to a month to grow a similar-sized diamond, with ongoing advancements potentially reducing these timescales.
Both timelines are approximate and can vary depending on the desired size, quality, and specific conditions of the manufacturing process. After the diamond is grown, additional time is required for cutting and polishing.
Lab-grown diamonds are indeed real diamonds with the same chemical, physical, and optical characteristics as natural mined diamonds. Consequently, they will test positive on standard diamond testing equipment, which is designed to identify the unique properties of diamonds, such as their thermal conductivity and hardness.
While lab diamonds are virtually indistinguishable from natural diamonds in tests commonly used by jewelers and consumers, there are advanced tests that can identify differences in crystal growth patterns and trace elements, which can distinguish lab-grown diamonds from mined diamonds. These advanced tests are typically used by gemological laboratories rather than in everyday settings.
Creating lab-grown diamonds at home is highly impractical and unlikely for several reasons:
Creating lab-grown diamonds at home isn't realistic because:
- Specialized Equipment: You would need advanced machines capable of generating extreme heat and pressure. Such setups are complex and expensive, beyond what a typical household could acquire or operate.
- Expert Knowledge: A deep understanding of the diamond-growing process is crucial. It's not a simple task and requires a background in materials science or related fields.
- Safety Issues: Both major methods for growing diamonds—HPHT and CVD—involve high-risk conditions (high temperature, high pressure, and hazardous gases) that would be dangerous to replicate at home.
- Cost: The cost of even the most basic equipment would be prohibitively expensive for an individual.
- Time and Monitoring: Growing diamonds takes weeks and requires constant monitoring to ensure the process is going correctly.
For these reasons, diamond growth is better suited to professional labs rather than a home setting.
In summary, while it's an interesting thought, the creation of lab-grown diamonds is firmly in the realm of industrial or specialized.
Yes, lab-grow diamonds can be created in a variety of colors. The color in diamonds, whether natural or lab-grown, arises from slight impurities or structural anomalies within the crystal lattice of the carbon atoms.
Through controlled processes, scientists can introduce specific elements or use certain treatments to produce colors such as yellow, blue, pink, brown, and green, among others. The two main methods for growing colored diamonds in the lab are High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD), and post-growth treatments can also induce color changes. It's worth noting that, just like in nature, creating a specific color in a lab setting can be complex and challenging, and some colors are rarer and more difficult to produce than others.
Companies create lab-cultured diamonds primarily using two methods:
- High Pressure-High Temperature (HPHT): A small diamond seed is placed in a carbon-rich environment and exposed to extreme pressures and temperatures, mimicking the natural conditions deep in the earth, causing the carbon to melt and form a diamond around the seed.
- Chemical Vapor Deposition (CVD): A diamond seed is placed in a chamber filled with a carbon-rich gas mixture (like methane). The gas is heated until it becomes plasma, which causes carbon atoms to accumulate on the seed, layer by layer, forming a diamond.
Both methods produce diamonds that are physically, chemically, and optically identical to mined diamonds. After creation, the diamonds are cut, polished, and may undergo treatments to enhance color or clarity.
Laboratory diamonds are indeed real diamonds, identical to mined diamonds in terms of their chemical composition, structure, and physical properties. They're created in laboratories using high-tech processes that replicate the natural diamond-growing conditions. The only fundamental difference between lab-grown and mined diamonds is their origin. Lab-grown diamonds are an ethical and often less expensive alternative to mined diamonds, but they are genuine diamonds by all gemological standards.
