Diamond Guide

"I've been involved in the diamond industry for 48 years. My wife, Darlene, is a 3rd generation jewelry professional. No one knows diamonds or the diamond industry like we do."          - Cliff Miller, Owner                                        

Buying a diamond is a very personal experience. Diamonds can be bought to signify love, significant accomplishments, milestones in your life or that of a gift's recipient. Unlike when you buy clothing, electronics, or cars, the features of a diamond may not seem quite so obvious to you. We would like to change that. The more you know about your diamond jewelry, the more confident you will feel when making your diamond jewelry choices. Take a moment to learn more about the 4Cs and find out how they play an important role in making your diamond jewelry unique.

"While this information is a great beginning, nothing beats the personal service MJ provides. Please stop in for a no-pressure education on the incredible diamond."

The shape of the diamond is often confused with the cut. Choose the shape that you like based on your style and you cannot go wrong. 

"However, beware... many people overpay for inferior diamonds that are not shaped correctly. Please allow us to provide you personal guidance in choosing the right shape."          - Cliff Miller, Owner

 Diamond Guide


The cut of a diamond determines its brilliance or sparkle. Each shape will be cut differently. Before a diamond is cut, the location of inclusions and flaws, the natural coloration, and the original shape of the rough stone are studied extensively. The stone facets are then mapped out and cut in a way that maximizes size, shape, and clarity. For optimal light performance, you will want a diamond that is cut neither too shallow nor too deep.

"So which factor drove the decision to create a specific diamond? If you don't understand, it could result in your purchasing an inferior diamond. Let MJ help you by explaining the different cuts and why diamonds are cut the way they are."          - Cliff Miller, Owner

Diamond Cuts


Diamonds are graded based on the amount of color they do or do not possess. The scale runs from D (colorless) to Z (light yellow). An absolutely colorless diamond is rare and therefore very valuable.

"If only it were that simple... Did you know that between two color grades there are many degrees of color? For example, if the color is a G, is the degree of color closer to an H? If so, it's less valuable. MJ has a staff of knowledgable professionals to help you understand color grading."          - Cliff Miller, Owner

Diamond Color Scale


A diamond is distinguished by its natural characteristics, just as a person would be noted for her blue eyes or his brown hair. Notated as a diamond's clarity, these characteristics can be present on the surface (blemishes) or within the stone (inclusions). The clarity is judged by the number and types of these characteristics and is designated using a scale that runs from Fl, defined as flawless, to I3, defined as inclusions visible with the naked eye. A flawless diamond is truly rare.

"What you're not told is how the location and color of the blemish or inclusion can strongly affect the price you should pay for a diamond. We would be happy to explain this further. Stop in or set an appointment with us today. We are here to help."          - Cliff Miller, Owner

Carat Weight

The unit of measure used for the weight of a diamond is the carat. As a matter of reference, a carat is equivalent to .2 grams or .007 of an ounce. Carat weight can also be divided further by using points. There are 100 points in one carat. So a 1/4 (.25) carat stone can also be expressed as 25 points and mean exactly the same thing. When comparing two diamonds, please note that just because one is twice the carat weight of the other does not mean that it will appear to be twice the size.

"With this information, you may think carat weight is a specific size which is not the case at all. If a 1 carat diamond was cut for maximum weight it could have the size (diameter) of a .90 carat or less. Watch out for hidden weight. But don't worry, we are here to help."          - Cliff Miller, Owner
