GIA (Gemological Institute of America) certified diamond cut grades are as follows: Excellent, Very Good, Fair and Poor. Furthermore, when it comes to diamond engagement rings, the most popular diamond shape is the round brilliant cut.

CLARITY

The clarity of a diamond is a measure of the degree of “imperfections” or flaws it contains. Imperfections can be found on the diamond surface, which are known as blemishes (scratches, pits, chips, etc.), or inside the diamond, which are known as inclusions (bubbles, cracks, dots, etc.). The clearer (or more flawless) the diamond, the higher its value. The GIA Diamond Clarity Grade scale consists of five main categories with 11 grades in all. The categories are: FL (Flawless), IF (Internally Flawless), VVS1-VVS2 (Very, Very Slightly Included 1 & 2), VS1-VS2 (Very Slightly Included 1 & 2), SI1-SI2 (Slightly Included 1 & 2), and I1-I2-I3 (Included 1, 2, & 3).

COLOR

When diamond jewelers speak of a the “color” of a diamond, they are usually referring to the hue or degree of yellowish tint in a white diamond (different color criteria apply to rarer “Fancy Color” diamonds [pink, yellow, orange, etc.], which have a more intense color grading). Colorless, white diamonds allow more light to flow through them, which makes them more brilliant and fiery. Thus, the more colorless the stone, the higher its value. The GIA (Gemological Institute of America) uses 23-letter (D to Z) color grading system, ranked from least amount (D) to most amount (Z) of color. The GIA color scale is divided as follows: D to F (Colorless), G to J (Near Colorless), K to M (Faint), N to R (Very Light), and S to Z (Light).

CARAT WEIGHT

A diamond’s weight is measured in “carats,” a unit of mass specifically used for measuring gemstones and pearls. Each carat can be divided into 100 parts or “points”. As the mass (or number of carats) of diamonds increases, the price increases exponentially. Many think that a 1-carat diamond is the ideal size for an engagement ring.

Diamonds

​There has always been a debate about diamonds being the ultimate investment. No matter what side your on, research shows that the value of diamonds have increased every year for over 50 years! With concerns about increasing world debt, stock market, and a worthless paper money system, diamonds might be a great alternative for you to invest your hard earned money and make it grow over time.

Gold bars are heavy and riskier to carry. Diamonds are small, easy to carry and store – the most concentrated form of wealth to carry!

The key when investing in diamond jewelry is to pay the best price possible, not retail. Zeidman's specializes in supplying you with high quality diamonds and elegant jewelry at competitive prices.

Cliches such as “Diamonds are a girl’s best friend” and “Diamonds are forever,” have been around forever, because it's the truth!

DIAMOND CERTIFICATES

Certified diamonds are stones that have been analyzed by a laboratory, which then issues a certificate with the specifications and quality of the diamonds. The 4Cs of each diamond (and more) are specified in the certificate.

The two most respectable certificates are those issued by the world renowned labs, the Gemological Institute of America (GIA) and the American Gem Society (AGS). Buying a GIA certified or AGS certified diamond allows you to make a more informed and intelligent decision when making your purchase, since you can compare the loose diamond to others with different certificates.

BUYING DIAMONDS – THE FOUR C’S

If you are in the market to buy certified diamonds, you might have heard about the 4Cs: the globally accepted standard for evaluating and classifying diamonds: Color, Clarity, Cut, and Carat Weight.

CUT

The “Cut” not only refers to a diamond’s shape (round, emerald, princess, etc.), but (more importantly) it’s quality (proportions, symmetry, and polish), which affect how well the diamond interacts with light; that is, it’s brilliance. Even though the cut grades of a diamond are subjective ratings, a diamond’s “Cut” is considered the most important factor affecting its beauty. The four
