Lab Grown vs. Diamond Simulants

It is important to note the major distinction between lab diamonds and diamond simulants. Diamond simulants, such as cubic zirconia and moissanite, look similar to diamonds but are not true carbon crystals. Simulants do not have the same chemical and physical properties as natural diamonds and therefore sell at much lower prices than man made diamonds. Simulants can be distinguished from natural or lab grown diamonds using only the naked eye. Natural and lab grown diamonds have thermal conductivity properties that differentiate them from cubic zirconia with a handheld diamond tester. Some lab diamonds, along with some natural colored diamonds, may be mistakenly identified as moissanites when using certain diamond testers due to similarity in their electrical conductivity.

Lab Created vs. Natural Diamonds

Our lab grown diamonds display the same physical, chemical, and optical characteristics as natural diamonds, and exhibit the same fire, scintillation, and sparkle. Using a jewelry loupe, man made diamonds are impossible to differentiate from natural diamonds. Lab created diamonds may exhibit different trace elements than natural diamonds that do not affect the appearance of the diamond. Lab grown diamonds can be distinguished from natural diamonds only with tests using specialized equipment.
Lab made diamonds in Canada available for purchase should always come with a gem certification identifying them as laboratory grown.

How do they make Lab Grown Diamonds in Canada?

Each laboratory-created diamond is grown by placing a diamond ‘seed’ into a chamber of heat and pressure. This chamber mimics the natural growing process. Crystallization occurs allowing the lab-grown diamond to mature within six to ten weeks. It is then cut, polished and graded by the same world-renowned labs that certify earth-mined diamonds. The following technique are most commonly used by laboratories, and will be the same techniques used for any lab grown diamonds in Vancouver:

CHEMICAL VAPOR DEPOSITION (CVD)

Chemical Vapor Deposition, or CVD, is a process used to create gem-grade diamonds as well as optics and semiconductors. The CVD process uses ultra-pure carbon-rich gasses in a controlled chamber. Carbon-based gasses, such as methane, are heated until they break apart allowing the carbon atoms within the gas to separate. These tiny carbon atoms fall onto a diamond substrate and build up layers resulting in a rough diamond crystal. This process takes between six to ten weeks and yields gem-grade Type IIa lab diamonds. In recent years, CVD research has gained popularity and now modified versions of CVD are being used. These processes differ in the means by which chemical reactions are initiated. Some of these variations include:

Low-pressure CVD (LPCVD) Ultrahigh vacuum CVD (UHVCVD)
Plasma-enhanced chemical vapor deposition (PECVD)
Microwave Plasma Vapor Deposition (MPCVD)
Ultrahigh vacuum CVD (UHVCVD)

How long does it take to grow a lab created diamond in Canada?

It takes approximately 2-3 weeks to grow a rough diamond in a diamond lab that will yield a 1ct polished gemstone. This size of stone is just about perfect for lab diamond engagement rings, or lab made diamond rings in general.

Cutting and polishing may take another 4-8 weeks, especially for a lab diamond ring. The longer a rough is left in the reactor, the greater chance of developing more inclusions or cracks. So, now you know! The next time you see a lab grown diamond for sale, or a stunning lab created engagement rings in the jewelry store, you’ll know how they were made!
