What are Lab-Grown Diamonds?

Lab-grown diamonds are created in a controlled environment using cutting-edge technology and have identical chemical, physical, and optical properties to diamonds mined from the earth. Grown diamonds begin as carbon seeds, and as heat and pressure are applied through Chemical Vapor Deposition (CVD) or High-Pressure High Temperature (HPHT) growing methods, the seed grows to form a rough diamond, which is then cut and polished into gems.

The 4Cs: Cut, Color, Clarity, and Carat

There are many things to consider when looking to purchase a diamond. The 4Cs of Diamond Quality is the universal method for assessing the quality of any diamond, anywhere in the world. Whether shopping for a mined diamond or a lab-grown diamond, the 4Cs are the same.


We often think of a diamond’s cut as its shape, such as round, cushion, or oval, but a diamond’s cut refers to how well its facets interact with light. The quality of a cut is defined by proportions and symmetry — as these characteristics have a tremendous impact on a diamond’s sparkle, brilliance, and fire. Cut grades range from poor to excellent, with excellent being the best cut possible.


A perfect diamond is completely transparent, having no hue or color. The absence of color is graded on a D-through-Z scale; D is colorless, and Z has the most color. D, E, and F diamonds are colorless, and G, H, and I are considered near colorless. These distinctions are often so subtle that they are invisible to the untrained eye; however, a diamond’s color grade can have a large impact on both appearance and price.


A diamond’s clarity depends on the absence or presence of inclusions and blemishes. Imperfections can range from imperceptible to the naked eye to obvious flaws in the gem and are classified into six major categories:


The diamond carat weight measures how much a diamond weighs. A metric “carat” is defined as 200 milligrams. Carat weight is typically displayed as either a fraction or decimal and is sometimes referred to as points. Each carat is subdivided into 100 points. This allows for very precise measurements to the hundredth decimal place. For example, a diamond weighing 0.50 carats could also be called a fifty-pointer. All else being equal, diamond price increases with carat weight. However, 100 points of diamonds are not equivalent to a single 1.00-carat gem in price or value.
