GDC Fine Jewelry Uses Only GIA- and EGL-Certified Diamonds

GDC Fine Jewelry uses only diamonds from the Gemological Institute of America (GIA) and the European Gemological Laboratory (EGL). Both GIA and EGL diamonds go through strict evaluation and testing before we receive them, ensuring that they are of the highest quality. While prices vary, both diamonds follow the grading of the four C’s created by GIA: cut, color, clarity, and carat. GIA and EGL have truly carved a name for themselves in the jewelry industry, and GDC Fine Jewelry is proud to supply both in our jewelry store.

How to Find the Perfect Diamond for You

From engagement rings, to necklaces, to jewelry appraisals, it is best to know that the diamond you choose is exactly what you are looking for. When you visit GDC Fine Jewelry in North Huntingdon, PA, we focus on the four C’s:


Those looking for the perfect diamond may find that the “ideal cut” suits them best. An ideal cut diamond is cut to exact proportions and is a round shape. A “premium cut” differs slightly from the ideal cut, but still has close proportions and shows off a magnificent touch. 

Those cut incorrectly may show an interior cut, making a diamond too deep or too shallow. This diminishes the shine as light sneaks through the bottom. Ideal cuts will allow brightness to bounce off of the diamond, giving a striking, brilliant appearance.


The total clarity depends on the amount of inclusions on a diamond. An inclusion is an imperfection that affects the overall grade, in turn lowering the cost of the diamond. Clarity grades include internally flawless, very, very slight inclusions, very slight inclusions, slight inclusions, and imperfect.


Contrary to popular belief, the amount of carats does not solely reflect the grade and cost of a diamond. A carat determines the weight of a diamond; one carat equals .2 grams (200 milligrams). A carat is divided into 100 parts, which are called points. This means a 25 point diamond weights a quarter carat, and so on. The “carat total weight” includes all diamonds in the piece.

Because of the natural creation of a diamond, smaller pieces are easier to come by. Cost of large diamonds may be based on rarity, not solely on weight, color, cut, or clarity.


While diamonds may appear colorless, they all have yellow or brown tones. Diamonds lose value the more apparent the color is.
