Conflict Free Diamonds

Joseph Gann Jewelers takes the utmost precaution in using only conflict free diamonds. All diamonds from our many sources have to go through the Kimberly Process. Established by the United Nations in 2003, the Kimberly Process documents every time a diamond changes hands with a guarantee it is not from a country of conflict — from the ground to us, and then to you.

There are other measures we use that go even further. Whenever possible, we use diamonds that have been mined in Canada. Also, our suppliers often are able to let us know from what country a specific diamond was mined.

Please do not hesitate to ask us about any of your concerns, and we will give you the latest information.


Diamonds By Joseph Gann

We at Joseph Gann Jewelers know that an educated consumer is a confident and satisfied customer.

Whether you are purchasing your first diamond or have purchased diamond jewelry before, our professional staff will educate and guide you in selecting the right diamond using the 4 Cs of diamond quality and value: Cut, Color, Clarity, and Carat Weight.

Joseph Gann Jewelers specializes in loose diamonds of all qualities in all shapes and sizes.We have a large selection of Round Brilliant, Princess, Cushion, Radiant, Asscher, Emerald, Oval, Pear, and others.

We carry Gemological Institute of America (G.I.A.) graded diamonds since the G.I.A. is the most accurate of all the grading laboratories.

In addition, each diamond is thoroughly double checked by one of our Graduate Gemologists because we are very particular with the diamonds we stock.

Our Gemologists will help you compare quality and value. You will realize that seeing the diamonds in person makes all the difference in selecting the right diamond.

In the end, you will feel confident that you chose the right diamond, one that you will be happy with forever.


Cut

THE CUT is the most important aspect of a diamond. A diamond that is cut to ideal proportions will reflect and refract the maximum amount of light back to your eye and therefore have more sparkle and brilliance.

The G.I.A. has standardized the Cut Grade for round brilliant diamonds.

They range in grade from Excellent to Poor. A diamond with a high cut grade will have more value than lower cut grades.

Our Gemologists select only the finest grades of diamonds.


THE PRECISION with which a diamond is cut and polished dictates the maximum amount of light the diamond will refract and reflect. The better a diamond has been cut, the greater will be its brilliance, sparkle and fire.

How a diamond handles light: It is the cut that enables a diamond to make the best use of light. A well cut diamond is comprised of facets with correct angles, which are perfectly placed to maximize the diamond’s sparkle. Therefore, a diamond cut to the proper proportions will have more value than one which is not.

1. Ideally cut: When a diamond is cut to proper proportions, light entering a diamond is reflected from one facet to another and then dispersed back through the crown or top of the diamond.

2. Too deep: Light escapes through the opposite side of the pavilion or bottom.

3. Too shallow: Light escapes through the pavilion before it can be reflected.


Color

DIAMONDS ARE FOUND with a range of colors. Although most gem-quality diamonds appear to be colorless, there are subtle differences in shade.

To determine a diamond’s true color, the diamond is viewed from the side and is compared to diamonds in a Master Set whose colors have been predetermined by the G.I.A. The color grading scale is from completely colorless to light yellow.

The difference between one grade and another is very subtle, as can be seen by the number of grades within any one category.

Diamonds with no races of color are extremely rare and more valuable.

Natural color diamonds, known as “Fancy,” are most common in yellow, graded from “Fancy Light” to “Fancy Vivid.” Diamonds are found in pink, blue and green, but they are very rare.


Clarity

NATURE HAS IDENTIFIED each diamond by natural inclusions: crystals, feathers, lines, etc. These traits developed in the diamond during its formation.

Diamond clarity is determined by the visibility of these inclusions, viewed by a trained eye under 10-power magnification.

The fewer and smaller the inclusions are, the less likely it is that they will interfere with the passage of light through the diamond, and the more beautiful the diamond will be.

While most inclusions may not affect the beauty of a diamond, they do affect its value and price.


Carat Weight

AS WITH ALL PRECIOUS GEMS, the weight of a diamond is expressed in carats. The “carat” originated as a natural unit of weight: the seed of the carob tree. Diamonds were traditionally weighed against these seeds.

The system was later standardized so that 1 carat = 0.2 grams. 1 carat is also divided into 100 points like 100 pennies in a dollar. This means that a diamond of 75 points weighs .75 carats or 3/4 carat.

The larger a diamond is, the rarer and therefore more valuable. Thus, a two-carat diamond will be more than double the price of a one-carat diamond of the same quality.
