Selecting Diamonds

Diamonds are graded for certification by laboratories using grading criteria. Four of these criteria are critical to understand when making a diamond purchase or investment. Known as the “Four C’s” these criteria are: color, cut, clarity and carat.

Color is the result of the composition of a diamond and it does not change. When a jeweler is describing the color of a diamond they are referring to the presence or absence of color in white diamonds. Because a diamond with no color allows maximum light to pass through, colorless diamonds are preferred for their sparkle.

Cut refers to a diamonds reflective quality. Most diamonds are cut with 58 facets. The brilliance of diamonds is heavily dependent on the cut. The different angles and the finish of a diamond determine its ability to reflect light and cause its brilliance and fire. Remember that the cut of a diamond can have an impact on its durability as well as its beauty. Some cutting faults can make a diamond prone to breakage. A diamond that is cut too thin can also cause light to leak out of the back and the diamond will lose some of the sparkle and appear not to shine. So, as you can see the Cut is probably the most important of the Four C’s.

During the formation process, inner flaws, or inclusions occur in most diamonds. The number and size of these inclusions determine what is referred to as the clarity of a diamond. Diamonds that are clear create more brilliance and therefore are rarer and highly priced. To be considered“flawless”, a diamond must have no surface or internal imperfections visible upon being viewed by a skilled diamond grader using 10 power magnifications.

Carat is the unit of weight by which diamonds are measured. One carat is equal to 200 milligrams. A carat is divided into 100 segments called points. 150 points would equal one and a half carats.

When you go to the store to make that all important diamond purchase, do not be shy! Ask questions, get the answers needed to make an informed purchase. Shopping for certified diamonds enables you to make an informed selection. Knowing the “four C’s” allows you to comparison shop and purchase the best diamond at a fair price. But, before making a purchase, shop around and decide what shapes and styles really appeal to you. Enjoy your diamond for years to come!

Buy Synthetic Diamonds ?

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!.

I know some of so call wealthy friend wearing synthetic diamond. Because the way they look and lifestyle, nobody dare to ask them ' Is that synthetic diamond ?'. I know their secret because they told me...Their reason is simple to protect from the robbery !. Is that true reason you wearing synthetic diamond ?. Make your own choice, natural or synthetic diamond.

What Are Dirty Diamonds?

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!

How to Buy Diamond Engagement Rings

There is much to consider when purchasing a diamond – especially diamond engagement rings! The tradition of presenting a woman with a diamond engagement ring when proposing began in
1477 when Archduke Maximilian presented a diamond ring to Mary of Burgundy – and in most cases, the woman you plan to propose to will expect a ring to accompany that proposal!

First, determine how much ring you can afford. Most people use the ‘two months salary’ rule. This means that the ring should cost the equivalent of two months of your current salary. Because you have other bills to pay, saving up this amount of money may take quite a bit of time. You should consider financing. Simply go to the jeweler of your choice and tell them that you plan to buy an engagement ring, and that financing will be necessary. Go ahead and get the credit check out of the way, find out what your payments will be, and how much of a down payment is required.

Now, have your mother, sister, or your girlfriends best friend take your girlfriend shopping, and make sure that they gaze at the engagement rings to get an idea of what she might like. Make sure that the jewelry store you buy the ring from will allow you to return the ring, if that is required, or allow your girlfriend to exchange it for another if she isn’t happy with it!

Beware of Diamond Scams

When it comes to diamonds, there are numerous scams to avoid. Most scams are minor, but there are some major ones that come up from time to time concerning the buying and selling of diamonds. Scams occur simply because most people who buy diamonds – for whatever reasons – don’t know that much about diamonds. Therefore, they are easily fooled.

A common scam that most jewelry stores participate in is the Carat Total Weight scam. The tag on the piece of jewelry, usually a ring, only states the total carat weight of all diamonds in the piece, instead of listing the total weights separately for each diamond. This leads consumers to believe that the main diamond in the piece is actually bigger than it is. Ask what the total carat weight of the center stone is. Also beware of fractions. Jewelry stores are allowed to round off diamond weights. This means that if the jeweler tells you that it is a ¾ carat diamond, it is probably between ½ and ¾ carat – but closer to ¾.

Jewelry stores often run ‘fluorescence’ scams to varying degrees. Referring to a diamond as a blue-white diamond is such a scam. A blue-white diamond sounds very unique and special, but in fact, this type of diamond is of lesser quality – even though the jeweler will try to make you think you are getting something special. Jewelry stores also like to show their diamonds in bright lights. Lights make diamonds shine. Ask to see the diamond in a different, darker type of lighting as well.

Some truly unscrupulous jewelers target those who want appraisals on diamonds that were given to them as gifts or that were purchased elsewhere. They will try to tell you that the diamond is worthless, or worth less than it actually is worth – and offer to take it off your hands or trade it for a much better diamond, along with the cash to make up the difference. This is called low balling. Get a second, third, and even a forth opinion before taking any action.

Another common dirty trick is to switch the diamond you have chosen and paid for with one of lesser quality and value when you leave it to be set in a piece of jewelry, or leave a diamond ring to be sized. The only way to avoid this is to do business with one trustworthy jeweler. Avoid jewelers that you have not done business with in the past.

There are many more scams that jewelry stores commonly pull on unsuspecting consumers. Just use your best judgment, and purchase your diamonds with the utmost care and consideration.

How 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.

How to Spot A Fake Diamond


In this world of advanced technology it is almost impossible to simply look at a diamond and determine whether it is real or not – especially if you don’t know much about diamonds. There are some steps that you can take to avoid buying a fake diamond.

First, only deal with reputable jewelers, and when you find a reputable jeweler, stick with
them. Avoid buying diamonds or other jewelry from jewelers that you have never dealt with before in the past. Ask to see the certificate for the stone. If no certificate exists, walk away.

Look at the setting that the stone is in. Fake diamonds, such as zirconias, are usually set in low quality metals. Take a close look at the stone. Fake diamonds are not durable –natural diamonds, on the other hand, are the most durable stone on the planet. Look for scratches or nicks.

After purchasing a diamond, take it to another jeweler for appraisal. In fact, take it to two or three other jewelers for an appraisal to make sure that the appraisals are all fairly close. If you find that you have purchased a fake diamond, you may be accused of making a switch when you return to the store of your purchase; therefore, it is important to have a certificate for the diamond. No two stones are alike.

How to Care for Your Diamond

Caring for a diamond takes more than occasional cleanings. Diamonds are forever, but they can be damaged if you are not careful. By learning how to properly care for your diamond, you will ensure that your diamond is indeed forever.

First, you should take your diamond jewelry to a jeweler once a year. Have him check the mountings and prongs that hold your diamond in place. Have him make any needed repairs. This will prevent your diamond from falling out of its setting and becoming lost.

Diamond jewelry that is not being worn, or diamonds that are loose should be stored in a fabric lined jewel case, or in a jewelry box where it can be kept separate from other jewelry. Each piece should have its own compartment. This will keep diamonds from becoming scratched, and it will also keep your diamond from scratching other jewelry as well.

Remove your diamond jewelry when doing physical work. Diamonds can be chipped and scratched easily. Also avoid allowing your diamond to come into contact with bleach or other household cleansers – this can damage or change the color of the settings and mountings, and it may even irreversibly change the color of the diamond.
