Lab Grown Diamonds
Lab grown diamonds (also called man-made diamonds and lab-created diamonds) are more beautiful, ethical and affordable than anything we will get out of the earth. We’re replicating the earth’s natural process by crystallizing carbon into brilliant diamonds that are chemically, optically and physically identical to earth-mined diamonds, but are priced up to 40% less, and free of any environmental or humanitarian concerns.
Think of this as making ice in your freezer versus getting it from a glacier; both are ice regardless of the origin.
“[Lab-created diamonds] are not fakes. They’re not cubic zirconia. They have all the same physical and chemical properties of a mined diamond.”
A lab-created diamond is “grown” inside a lab using cutting-edge technology that replicates the natural diamond growing process. The result is a man-made diamond that is chemically, physically, and optically the same as those grown beneath the Earth’s surface.
IS IT A REAL DIAMOND?
Yes it is a real diamond, even the most sophisticated gem laboratories certify it as diamonds.
How Are Lab Diamonds Made?
Before we talk about how lab-created diamonds are made, it’s important to understand how mined diamonds are formed. The processes are extremely similar – only one happens naturally while the other occurs in a lab
Our lab created diamonds are grown from the tiny carbon seeds of pre-existing diamonds. Advanced technology – either extreme pressure and heat or a special deposition process known as CVD – mimics the natural method of diamond formation. Some lab diamonds grown through deposition may also undergo pressure and heat treatment after they are grown. Lab grown fancy colored diamonds are formed when small amounts of specific trace elements are present during the growth phase of the diamond, just like in nature. In both white and fancy colored lab diamonds, the exact composition of trace elements may differ from their natural diamond counterparts. Lab diamonds can only be distinguished from natural diamonds using specialized equipment that can detect the minor differences in trace elements and crystal growth.
Lab-created Diamonds There are two processes labs use to grow diamonds – High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD).
HIGH-PRESSURE HIGH-TEMPERATURE (HPHT)
HPHT diamonds are made using one of three manufacturing process: a belt press, the cubic press, and the split-sphere (BARS) press. All of these processes create an environment of extremely high pressure and temperature conducive to diamond growth.
An HPHT diamond begins as a small diamond seed that is placed into carbon. Using one of the manufacturing processes above, the seed is exposed to temperatures of about 1500 degrees Celsius and pressurized to approximately 1.5 million pounds per square inch.
The pure carbon melts and starts to form a diamond around the starter seed. It is then carefully cooled to form a pure carbon diamond.
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 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)
HOW IS IT DIFFERENT FROM MOISSANITES?
Moissanites are just another gemstones which have properties similar to a diamond and in case of solitaires they are still the best option to go for since solitaires of lab grown diamonds are still quite expensive and are around 50% price of Mined diamonds while Moissanites are only 10% of mined diamonds.
IS IT AVAILABLE IN ALL COLOR AND CLARITY?
Yes lab grown diamonds are available in all color and clarity just like mined diamonds but Customize Jewels believes in quality and so with Customize Jewels jewelry we use only EF Color and VVS – VS clarity with excellent cut to give the best to its clients.
DOES IT FADE OR BECOME CLOUDY WITH TIME?
No! it stays forever just like a mined diamond.
