FAQ's

If you thought there were only four Cs, then we should talk

Color. Cut. Clarity. Carat. For many years, the four Cs have been the accepted standard. It is our belief that Certification must now be considered a key factor in valuing diamonds. At Jewelry Exchange of Maryland, we go beyond the easily measured carat weight, and we'll give you the full story of a diamond.

Diamond Carat Weight

A diamond's size is measured in carat weight. The larger a diamond is, the more valuable it is. Having said that, diamonds of equal size may vary widely in value and brilliance based on qualities of clarity, cut and color.

Diamond Clarity

Like any natural substance, diamonds contain identifying characteristics. While these natural phenomena, called inclusions, may not be visible to the naked eye, they can usually be seen through a jeweler's 10x magnifying loupe or microscope. Mirroring nature, these inclusions often look like tiny crystals, clouds or feathers. The size, nature, color, location and number of inclusions determine a diamond's clarity grade and value.

Diamond Color

Diamonds are graded by color starting at D and continuing through the alphabet. Most people choose a diamond between the grade D to K, because they appear white when mounted. After the grade of Z, diamonds are considered "Fancy Colored" and can command as much as colorless diamonds. The color spectrum includes red, blue, pink and green.

Diamond Cut

We hold Cut as the single most important factor in determining the beauty and brilliance of a diamond. Over 38 years of experience, we have seen well-cut diamonds to hold their value more consistently than any other.

Diamond Certification

We offer a wide selection of AGS, GIA and EGL certified diamonds and quality non-certified diamonds for you to choose from. Of the certification labs, the GIA (Gemological Institute of America) certification consistently offers the highest standard in the diamond industry, and no matter which diamond you choose, you’ll benefit from the expertise of our on-staff GIA-certified gemologist.
