Diamonds are considered to be inelastic in terms of their physical properties, meaning they do not easily deform or stretch when subjected to external forces.
Diamonds are primarily composed of carbon atoms arranged in a crystal lattice structure, making them a chemical substance. Physically, they are known for their exceptional hardness, brilliance, and thermal conductivity. While the chemical composition is uniform, diamonds can vary physically in terms of size, shape, color, and clarity due to impurities and structural defects. Thus, diamonds exhibit both chemical and physical properties.
Coal is similar to diamonds in that both substances are made from the element carbon.
Generally, people do not "invest" in diamonds. Diamonds are valuable in terms of profit if they can be sold for more than than the seller paid. But the price does not go "up or down;" there is no speculating.
The "traditional" diamond is colourless and transparent. However, diamonds come in a variety of colours including pink, brown, black, yellow, and red.
All of the world's diamonds come from the earth. They can be found on every continent except Europe and Antarctica. Many diamonds come from Africa, but Canada and Australia are not far behind in terms of gross production.

A greater emphasis on customized training reflects the needs of trainees, both in terms of the skills and knowledge they currently have and those that they need, along with identifying the unique learning style of each individual.
The best diamonds are often referred to as "ideal cut" diamonds. These diamonds are cut to precise proportions to maximize brilliance and fire. Other terms used to describe top-quality diamonds include "excellent cut," "Triple Excellent," or "Hearts and Arrows" diamonds.
Diamonds are considered rare in terms of high-quality gemstones, but they are not rare in terms of natural occurrence. While large, flawless diamonds are scarce, millions of carats of lesser-quality diamonds are mined each year. Moreover, the diamond market is heavily controlled by companies, particularly De Beers, which influences supply and demand, creating an illusion of rarity for high-quality diamonds. Thus, while they are not rare in nature, their perceived value is maintained through marketing and limited availability of premium stones.

Some chocolate diamonds are mined in Australia and comparatively, they cost less than clear diamonds. Diamonds are graded by what is commonly referred to as the three c's. Cut, Colour and Clarity. The better the cut, colour (rather clearer and not included) and clarity the more expensive the diamond will become.
