Diamond Color: We think color is one is one of the most important factors to consider when selecting a diamond because it is one of the first things most people notice-whether or not the diamond is "white". It is also one of the most significant factors affecting value. Today, the color designation frequently used to grade an absolutely water clear, colorless diamond is the letter D. The GIA classification progresses from D, the finest classification on this scale (colorless), through the alphabet Z, getting progressively yellower.

D: Absolutely colorless. The clearest diamond color grade, which is very rare.

E: Extremely colorless. Trained gemologists can detect slight color. A high-quality diamond.

F: Colorless. Only trained gemologists can detect color. Lowest of the colorless grades.

G-H: Near-colorless. When compared to better color grades, slight color detectable, but is a much better value.

I-J: Near-colorless. Color slightly detectable. An excellent value.

K-M: Sndgems does not carry these color grades.

D, E, and F can all be grouped as exceptionally fine and may be referred as "colorless," "exceptionally white" or "rare white". G and H may be referred to as "fine white" or "rare white." These grades are considered very good. I and J colors are slightly tinted white. K and L show a tint of yellow or brown.

What is fluorescence? If the diamond you are considering is accompanied by a diamond grading report, it will indicate whether the diamond has some degree of fluorescence. This is a property that some stones posses which causes them to appear a different color in some lights than in other lights. A diamond that fluoresces might look white that it is really in certain light. Related to diamond color, fluorescence is a unique effect that causes a diamond to produce a slight blue glow when exposed to intense, direct ultraviolet light. Some people seek diamonds that produce this unique effect, while others definitely want to avoid it — it's purely a matter of taste.

For the purist, look for a colorless diamond with a grade of D-F and a fluorescence rating of none, faint, or slight.

For an excellent value in a diamond with no noticeable color to the unaided eye, look for a near-colorless grade of G-I, and a fluorescence grade of medium or strong blue.

Or, if you'd rather not compromise on color but would like to stay on budget, choose a diamond with a good cut and SI1–SI2 clarity and consider going with a strong fluorescence. It will still be beautiful to the unaided eye and you may prefer the unique effect of a strong fluorescence.

Diamond Clarity

Diamonds that are absolutely clean are very much in demand and are therefore the most expensive. View Details.


Diamond Cut

In its natural state, a diamond's beauty is generally concealed. While nature determines a diamond's color, clarity, and carat weight, the hand of a master craftsman is needed to release its fire and beauty. View Details.


Carat Weight

Diamonds are sold by the carat (ct)-not to be confused with karat (kt), which refers to gold quality in the Unites States. Once you've determined what cut, color, and clarity grade you're looking for in a diamond, it's easy to determine the carat weight of diamond that will fit within your budget. View Details.
