Red Flags
Of Diamond Buying

Sell Me Financing

Is your salesperson focused on fulfilling your needs or processing a credit application? Credit is a great tool to acquire the diamond of your dreams, but the focus should be finding that diamond.

Know Your Labs

Did you know that not all laboratories grade the same. The definition of color and clarity varies from lab to lab. Make sure to visually inspect similar pedigree diamonds for differences keeping in mind that the whiter and cleaner a diamond is, regardless of what the document says, valued higher.

Read the Fine Print

They promise the world, and then you read the fine print. Be vigilant when examining return policies, warranties and service contracts. The peace of mind you felt while reading the bullet points can provide a false sense of security.

4 C's of Diamonds


A polished diamond’s proportions, or “cut,” affect its light performance, which in turn affects its beauty and overall appeal. Diamonds with fine proportions, symmetry, and polish optimize their interaction with light and have increased brightness, fire and scintillation.

Thin Cut

If the stone is cut too shallow, much of the light fails to be refracted at all and leaks out of the bottom.

Excellent Cut

When light enters a properly cut diamond, it is refracted from facet to facet and comes back through the top to the eye.

Thick Cut

If a stone is cut too deep, much of the light is refracted at the wrong angle and lost out the side.


Although many people think of gem quality diamonds as colorless, truly colorless diamonds are actually very rare. Most diamonds used in jewelry are nearly colorless with tints of yellow or brown.

Color grades are determined by comparing each diamond to a master set. Each letter grade represents a range of color and is a measure of how noticeable a color appears

Near Colorless
Faint Yellow
Very Light Yellow
Light Yellow


The weight of a diamond is measured in carats. It is the easiest of the four characteristics to determine.

A carat is 200 milligrams (1/5 of a gram) and is divided into 100 points (like pennies to a dollar). Thus a half carat stone is a diamond of 50 points and is listed as 0.50 carat.

0.50 Carat
0.75 Carat
1.00 Carat
1.25 Carat
1.50 Carat
1.75 Carat
2.00 Carat
3.00 Carat


Clarity is determined by the number and size of internal characteristics (called inclusions) and external characteristics (called blemishes) which both occur naturally in diamonds. Small inclusions that are visible only under magnification are not likely to diminish the beauty of a diamond. The smaller the inclusion, the less likely that it will interfere with light as it passes through the diamond.

These grades contain minute inclusions so small they are difficult to locate under 10x magnification. Pinpoints, faint clouds, tiny feathers, bruises or internal graining characterize the VVS grades.


These grades contain minor inclusions of a size, number and location between those difficult to locate and those somewhat easy to locate under 10x magnification. Small included crystals, small feathers and distinct clouds characterize the VS grades.


These grades contain noticeable inclusions which are easily visible under 10x magnification. Diamonds in these grades may disclose inclusions to the unaided eye when placed table down on a white background, but rarely when viewed face up.


The imperfect categories contain inclusions which are obvious when viewed under 10x magnification and which may be visible to the unaided eye in the face-up position.
