Like other industries, the diamond industry is constantly innovating and adapting. Many decades ago, people depended on finding rough diamonds in diamond mines. Today, we have laboratories that can simulate the growing process of diamonds.
Each laboratory-created diamond is grown by placing a diamond ‘seed’ into a chamber of heat and pressure. This chamber mimics the natural process of growing diamonds.
Crystallization occurs, allowing the lab-grown diamond to mature within six to ten weeks. Next, laser drills cut the stone. Afterwards, world-renowned labs polish and grade these stones.
These labs also certify earth-mined diamonds. Having only one source to grade and certify diamonds ensures excellent quality control. It also ensures that the standard remains consistent for all diamonds that enter the market.
Diamond laboratories commonly use this technique. It will be the same technique used for any lab-grown diamonds in Vancouver.
Chemical Vapour Deposition, or CVD, is a process that creates gem-grade diamonds. It also produces optics and semiconductors. The CVD process uses ultra-pure carbon-rich gasses in a controlled chamber.
The process heats carbon-based gasses, such as methane, until they break apart. It allows the carbon atoms within the gas to separate. These tiny carbon atoms fall onto a diamond substrate and build up layers. As they build up, they create a raw diamond crystal.
This process takes six to ten weeks and yields gem-grade Type II-A diamonds.
Variations to CVD
More people have become aware of CVD in recent years, thanks to research. Today, labs use modified versions of CVD. These processes differ in how they initiate chemical reactions. Some variations of the CVD process include:
- Low-pressure CVD (LPCVD) Ultrahigh vacuum CVD (UHVCVD)
- Plasma-enhanced chemical vapour deposition (PECVD)
- Microwave Plasma Vapour Deposition (MPCVD)
- Ultrahigh vacuum CVD (UHVCVD)
It takes approximately 2-3 weeks to grow a diamond. Each stone that comes from a diamond lab has a grading report.
Often, diamond labs create a 1ct polished gemstone. This stone size is just about perfect for lab-diamond engagement rings and generic diamond rings.
Cutting and polishing may take another 4-8 weeks, especially for a lab-diamond ring. The longer a rough diamond stays in the reactor, the greater chance of developing more inclusions or cracks.
One glance at a diamond isn’t enough to determine if a diamond is natural or lab-grown. The naked eye can never see the differences between a lab-grown and natural diamond.
You need to go to a diamond expert to find out if a diamond is natural or man-made. They have the tools and training necessary to determine which is which.
The biggest determiner is the presence or absence of nitrogen. Lab-grown diamonds don’t have nitrogen in their composition. Meanwhile, natural diamonds have minute quantities of the element.
Absolutely! Lab-grown and natural diamonds are both real diamonds. A diamond that comes from a lab isn’t a fake or imitation.
Remember that lab-created diamonds still have the same composition as natural diamonds. These man-made diamonds have the same hardness rating and durability as natural diamonds. The only difference is their origins and how long it took them to form.
Lab-grown diamonds are more affordable than natural diamonds. Guaranteed origins or sources is another reason to buy lab-grown diamonds. They are also conflict-free diamonds. Because the diamonds come from a lab, they are less likely to be products of war, human rights violations, child labour, or the weapons trade.
Another reason to get the best lab-grown diamonds Vancouver has to offer is that they’re eco-friendly. You can even get various coloured diamonds now, thanks to the technology used in modern diamond labs. They’re a perfect choice if you prefer to buy a guilt-free engagement ring.
Now, you know how Vancouver lab-grown diamonds came to be. Next time you go shopping for a diamond ring, you’ll be more aware of diamond origins and sources.
