When it comes to finding a great diamond, everyone has heard of the 4 C’s:

#1 Color. Color is a rating from D, E, F, G, H, I, J, K, and so on. A little-known fact is that there are no A, B, and C ratings. The GIA scale gem white is colorless, the color D. The better the color the more the cost. #2 - Cut. This is the shape of the diamond, be it, round (brilliant), emerald, princess, oval, or pear. The cut is how well the material is made - symmetry and polish are key to the brilliance of a diamond.

#3 - Carat. This is measured by weight. One hundred points are equal to one carat. The larger the stone the more the cost. Sometimes a few points can cause a very large increase in price, especially right around the full carat mark.

#4 - Clarity. A stone can be flawless, internally flawless, have flaws not perceived by the human eye, eye imperfect can have many different and various flaws of different sizes that can be seen by the naked eye. We use a ten powered jeweler's loop to view the diamond. The cleaner the stone the more the value.

The combination of cut and brilliance can also influence the price dramatically. A professional should take the necessary time to explain all the issues and find the right product for you.

Now, let's talk about the other 3 C's that you should be thinking about when making the largest purchase besides your car or house:

#5 - Cost. The professional should set a standard of how much you should invest in the diamond versus the mounting for example. A good salesman will spend his customers budget wisely versus his needs.

#6 - Common Sense. If something looks better than the quality goes with it versus the perfection with certain limitations. Some people get so concerned about the certification to write up, that they wind up with a piece of paper versus the best looking final product they could have afforded.

#7 - Customize. We have to customize the product for the event. For example, the event could be an engagement, wedding, anniversary, or birthday. These occasions we cherish and remember and hand down from one generation to the next. People who give it and receive it will always cherish it.

All the 7 C's are very important. You need a trustworthy professional to explain the ins and outs of all these and what is important to your needs.
