What does the CAD and CAM part of "CAD CAM mean exactly ?
Computer-Aided design and computer-aided manufacturing, computer systems used to design and manufacture products. The term CAD-CAM implies that an engineer can use the system both for designing a product and for controlling manufacturing processes.
For example; once a design had been produced with the design component, the design itself can control the machines that contruct in part .
Computer-Aided design (CAD) is the use of computer systems to assist in the creation, modification, analysis or optimization of a design, CAD software is used to increase the productivity of the designer, improve the quality of the design, improve the communication through documentation and to create a database for manufacturing. CAD out is often in the form of electronic files for print, machining or other manufacturing operations.
Computer-Aided manufacturing is the use of computer software to control machine tools and related machinery in the manufacturing of workpieces. CAM is a subsequent computer-aided process after computer aided design (CAD), as the model generated in CAD can be input into CAM software, which then controls the machine tool.
What is 3D CAD design ?
3D CAD is the process of developing a mathematical representation of any three dimensional surface of an object (Either inanimate or living ) via specialized software.

How do you pick a Diamond ?
The 4 Cs...
Diamond color actually means lack of color. The diamond color evaluation of most GEM-Quality diamonds is based on the absence of color. A chemically pure and structurally perfect diamond has no HUE, like drop of pure water, and consequently, a higher value.
Diamond clarity refers to the absence of inclusions and blemishes. Natural diamonds are the result of carbon exposed to tremendous hear and pressure deep in the earth. This process can result in a variety of internal characteristics called "Inclusions" and external characteristics called "Blemishes". Evaluating diamond clarity involved determining the number, size, relief, nature and position of these characteristics. As well as how these affect the overall appearance of the stone. While no Diamond is perfectly pure, the closer it comes, the higher is its Value.
Diamond's cut brings out its inner light. Diamonds are renowned for the ability to transmit light and sparkle so intensely. We often think of a diamond's cut as a shape (round, emerald, pear), but a diamond's cut grade is really about how well a diamond's facets interact with light.
Diamond carat weight is the measurement of how much a diamond weights. A metric "Carat" is defined as 200 Milligrams. Each Carat can be subdivided into 100 "points". This allows very precise measurement to the hundredth decimal place. A Jeweler may describe the weight of a diamond below one carat by its "points" alone. For instance, the Jeweler may refer to a diamond that weighs 0.25 carats as a "twenty five pointer". Diamond's weight greater than one carat are expressed in carats and decimals. A 1.08 carat stone would be described as "one point to eight carats". All else being equal, diamonds of equal carat weight can have very different values (and Prices), depending on there other factors of the diamonds. It's important to remember that a Diamond's value is determined using all 4Cs, not just carat weight.
