What Are Man Made Diamonds?
Man made diamonds, also known as engineered or cultured diamonds, are grown in highly controlled laboratory environments using advanced technological processes that duplicate the conditions under which diamonds naturally develop when they form in the mantle, beneath the Earth’s crust. These man made diamonds consist of actual carbon atoms arranged in the characteristic diamond crystal structure. Since they are made of the same material as natural diamonds, they exhibit the same optical and chemical properties.
Our lab grown diamonds are now readily available in a variety of colorless ranges. Cultured diamonds are also available in fancy colors that are considered very rare in nature, including popular hues of vivid fancy yellow. Fancy colored lab diamonds sell at comparatively reasonable prices compared to their natural colored diamond counterparts.

How Are Lab Diamonds Made?
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 Grown Diamonds 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. However, gemologists can typically distinguish between diamond and moissanite due to their differing refractive properties, with moissanites being double refractive and diamonds being single refractive.

Since diamonds form under extreme heat and pressure, internal and external characteristics are common. These characteristics help gemologists separate natural diamonds from synthetics and simulants, and identify individual stones.

CUT

CUT

While nature determined the color and clarity of a natural diamond, man is responsible for the cut quality which brings it to life. The planning, proportions, cutting precision and details of finish determine how brilliant, dispersive and scintillating the diamond will be. If the cutting factors under man's control are not optimized, the appearance of the diamond can be adversely affected.
