A diamond is the hardest material on the earth and the most expensive gemstone as well. Diamonds are not rare but high-quality diamonds that can be used in the jewelry are rare. In addition, the size and quality of the diamond also plays a major role on the price. These are the reasons why diamonds are so expensive.

Diamonds are not particularly rare. In fact, compared to other gemstones, they’re the most common precious stone found. Generally, the cost per carat (or weight of a gemstone) is based upon a stone’s rarity; the rarer the stone, the more expensive.

The rarity combined with the demand for rich red gems keeps the price very high. Among rubies though, there is no shortage of small gems, the kind used in cluster rings. They are somewhat expensive, but readily available. The Carmen Lucia Ruby is an incredibly rare ruby due to both its size and quality.

Painite is a very rare borate mineral. The mineral’s rarity is due to the fact that zirconium and boron rarely interact with each other in nature. The crystals are naturally hexagonal in shape, and, until late 2004, only two had been cut into faceted gemstones.

Although most black diamonds on the market today are either superheated or irradiated to an almost black color, natural black diamonds do exist, though they are extremely rare. Carbonados, sometimes called “black diamonds,” are a distinct and unusual polycrystalline material.

To determine if your diamond is real, hold a magnifying glass up and look at the diamond through the glass. Look for imperfections within the stone. If you’re unable to find any, then the diamond is most likely fake. the majority of real diamonds have imperfections referred to as inclusions.

Naturally, people assume that the holes are there to allow the diamonds air to, well, breathe? But the holes are actually there to make it easy to clean the diamonds, and to make the diamonds easier to set without accidentally chipping the Culet (pointy tip of the diamond).

Fog Test – Breathe on the Diamond Use a tweezer or hold it between your two fingers, then breathe on it. The diamond will fog because of the heat and moisture in your breath. This is because diamonds can conduct heat and thus, disperse heat right away.

Can you reuse diamonds? Yes. Diamonds are the best stone for repurposing because they are the toughest and most durable. This is why diamond jewelry lasts and is passed down through generations.

Re-cutting into smaller diamonds would likely result in a 50% loss of weight (size) and even more loss of value. Much, if not all, of the material that is left over from making the one carat diamonds would be just grit for polishing other diamonds.
