There are many different cuts of diamonds to choose from. The cut essentially refers to the shape that the diamond is cut into – unless you are in the diamond or jewelry business, but this shape has a great impact on the much the diamond sparkles.
The most popular cuts are heart, marquise, oval, pear, princess, round, trillion, and emerald cuts. The shape has an impact on how much the diamond sparkles, but the actual cutting itself – when the diamond cutter actually cuts the diamond into a particular shape – also matters a great deal. If the diamond is poorly cut, it will lose its sparkle.
However, in the diamond industry, the cut of a diamond doesn’t refer to its shape at all. Instead, this is a reference to the stone’s depth, width, brilliance, durability, clarity, and other aspects of the diamond. Common cutting problems include a missing or off center culet, misalignment, a diamond that is too thick or too thin, cracks, or broken culets.
When shopping for a diamond, you should of course choose the shape that you like the best, but then look at several different diamonds of that shape to find the one with the best cut – the one that sparkles the most, in all types of lighting.

Selecting Diamonds

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!

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 shouldbe 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 trackrecord. 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.

How to Care for Your Diamond

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!

The Clarity of Diamonds

Many people mistakenly think that diamond clarity refers to how clear it is. This isn’t so. Clarity actually refers to the internal and external imperfections of the diamond. The best diamonds, of course get a grade of FL or IF – Flawless or Internally Flawless – meaning that it is perfect. A grade of I-1, I-2 or I-3 means that the diamond is imperfect, with a grade of I-3 being the worst.
Other grades are VVS1 and VVS2, which means that the diamond is very, very slightly imperfect; VS1 and VS2, meaning the diamond is very slightly imperfect; SI-1 and SI-2, which means that the diamond is slightly imperfect.

How to Insuring Your Diamonds

The first type of insurance policies for diamonds is an Actual Cash Value policy. If the diamond is lost or damaged beyond repair, the insurance company will replace the diamond at today’s market value, no matter how much you paid for the diamond to begin with. This type of insurance policy for diamonds actually is not that common.
The most common type of insurance for diamonds is Replacement Value insurance. The insurance company will only pay up to a fixed amount to replace the diamond that was lost or damaged beyond repair. This does not mean that they will pay that amount – it means that they will pay up to that amount. In most cases, the diamond can be replaced at a lower cost.
The third type of coverage offered for diamonds is Agreed Value. This is sometimes called ‘Valued At.’ This type of coverage is very rare. In the event that the diamond is lost or damaged beyond repair, the insurance company simply pays you the amount that you and the company agreed upon. This is the best type of insurance to have, but it is rarely offered. If you can’t get Agreed Value coverage, Actual Cash Valuecoverage should be your next choice.
Your rates will be determined by the value of the diamond, the type of coverage that youselect, and the area that you live in. If you live in an area with a high crime rate, you can expect to pay more for your diamond insurance coverage. It is important to remember that insurance agents are not qualified jewelers, and jewelers are not qualified insurance agents. It is best to get a certificate for your diamond, and to provide the insurance company with a copy of that certificate. This leaves the insurance company less room for arguments over the actual value of the diamond.
Don’t rely on separate coverage to cover your diamond. For instance, if you diamond is stolen from your home, it is probably covered on your home owner’s insurance policy – but the diamond probably won’t always be in your home, and once it leaves your home, there is no coverage.
