colored diamonds

Fancy colored diamonds are all the rage these days. Gemologists have developed new ways to create versions that are affordable for the average person - by treating less desirable diamonds. These less desirable diamonds are treated with irradiation followed by intense heat. This turns brown and yellowish diamonds into beautifully colored diamonds that you can afford. This produces stunning greens, blues, yellows, reds, purples and other colors. These colors are considered permanent, but there is a possibility they could change during repairs if a high heat is used.

Treatments like irradiation make it possible for more people to own these vividly colored diamonds. Most natural colored diamonds are rare and also extremely expensive. When shopping for colored diamonds you need to assume that any affordable fancy color diamond has been treated. Ask about the stones origin and request to view a lab certificate to verify authenticity.

Synthetic colored diamonds are another option if owning a colored diamond is something you desire but cannot quite afford. They are real diamonds, but they are created in a lab.

Natural fancy color diamonds get their coloring from different trace elements present in the stones, such as nitrogen, which produces a yellow diamond. Diamonds can be colored by exposure to radiation during its creation. An example of a diamond affected by radiation is a Green diamond.

Another way that a natural colored diamond gets color is by its inclusions. Regarded as flaws and undesirable in a colorless diamond, inclusions give unique tones and brilliant flashes of color in a fancy color diamond. Remember that Natural fancy colored diamonds are very expensive, any colored diamond labeled to be sold as natural should be accompanied by a certificate from a respected grading lab.

A "fancy" diamond is a natural diamond that has color. These colors vary from red, green, purple, violet, orange, blue and pink – and most shades between. Fancy color shades vary from faint to intense.

The most famous diamonds in the world are Color diamonds. The Tiffany Diamond, which is yellow and the Hope Diamond which is blue are colored diamonds. Color diamonds have an amazing financial track record. The value has never decreased on wholesale level in more than 30 years. Blue and pink diamonds have doubled every 5 years of a strong economy. In the 1970’s you could have bought a very high quality blue diamond for about 50K and today the very same stone would be worth between 2 and 3 million.

synthetic diamonds


We already know that diamonds are rare. We also know how diamonds are mined. But we don't know what synthetic diamonds are. If you want to know what synthetic diamonds are, please continue reading this article.

The first synthetic diamonds were produced by General Electric in 1954. A synthetic diamond is basically a rock that has the durability, refractive index and hardness of a natural diamond – but it is made by man. A synthetic diamond should not be confused with stimulant diamonds, such as glass, cubic zirconia, or moissanite.

Although the technology for synthetic diamonds came into play in 1954, no synthetic diamonds were ever seen on the market until the 1990’s. This was due to the fact that it took many years for General Electric to produce a synthetic diamond that could compare with the quality of a natural diamond – and when they figured out how to do it, they found that it cost more to produce a synthetic diamond than it did to mine and cut natural diamonds.

Finally, a small company by the name of Gemesis Corporation figured out a way to produce synthetic diamonds that were of the same quality as natural diamonds, at a cheaper price. Today, Gemesis produces synthetic white diamonds, and colored diamonds as well. These diamonds sell for about 1/3 of the cost of a natural diamond, but there is a shortage of them, and they are hard to find. In fact, it seems that synthetic diamonds are rarer than natural diamonds

How Diamond Ring Are Mined

We already know where the diamond ring are mined, and we also already know how rare the diamonds are. Today we'll learn about how the diamonds are mined.

We seldom think about how the diamonds we wear came to us. Natural diamonds, as opposed to synthetic diamonds or fake diamonds, are mined from the earth. There are currently two methods of mining diamonds: Pipe Mining and Alluvial Mining.

When pipe mining is used, the diamonds are extracted from the earth through volcanic pipes. These are not man-made pipes. These are natural pipes in the ground. Shanks are put into the ground next to the pipes, and tunnels are driven into the deepest parts of the pipe. The diamonds are not sorted out at the mine. Instead, huge rocks that are full of diamonds are brought out of the mine and moved to a screening plant for separation.

The Alluvial mining method is done in riverbeds and on beaches. Walls are built to hold back the water and the sand on the bank or beach is moved with a bulldozer until the level of earth that diamonds can be found in is reached. Again, the diamonds are not sorted here. Instead, the sand that contains the diamonds is bulldozed into trucks, and taken to screening plants.

Are Diamonds Really Rare?

When you walk into a jewelry store and see all the diamond ring in all of the various settings that are for sale, it is difficult to realize that diamonds are indeed rare. Most people don’t even stop to consider how that diamond came to be sitting in that jeweler’s case! There is quite a bit of work that is done before a diamond is ready to sell to the general public!

For every one million diamonds that are mined, only one will be found that is a quality one caret diamond. In order to find a two caret diamond, about five million diamonds must be mined. More than two hundred tons of ore must be mined to find one small diamond, and even then, more than 80% of the diamonds that are mined are only good for industrial use, such as diamond drill bits.

So, the next time you visit your local jewelry store, ask to see the one carat diamonds. You should look at this diamond with new appreciation – knowing that it truly is one in a million!

What Are Dirty Diamonds?

We already know where the diamonds are mined, and we know that diamonds are really rare. Right now, we'll learn about dirty diamond. A dirty diamond is one of two things: a rough diamond, or a diamond that hasn’t been cleaned in a while. Rough diamonds are uncut and unpolished – hence, they are dirty. But that type of dirty diamond will soon be cut and polished and sitting in a beautiful jewel box in a display case. Then someone will purchase it, and before long, it will become a dirty diamond once again.


Diamonds become dirty. When you wash your hands with a diamond ring on, soap scum clings to it. When you put on hand lotion, it gets grease on it. Shower with your diamond earrings or necklace, and again, you get soap scum. In one short day, your brand new diamond could be dirty!

Purchase an ultrasonic jewelry cleaner the same day that you purchase your diamond jewelry, and use it every single day, without fail. The clarity of the diamond changes when the diamond is dirty – it loses its sparkle. By taking one minute each day to clean your diamond jewelry, you can avoid this, and your diamonds will never be dirty!
