Jewelry Care

Professional Cleaning & Examination

The best way to care for your fine jewelry is to bring it in for a complimentary professional cleaning and inspection, which will bring out the beauty in your fine jewelry and gemstones. We'll also be able to inspect your jewelry for wear and advise you on maintenance that may be necessary to keep your gemstones secure.


Keeping jewelry looking its best and avoiding faster than normal wear requires some discretion on when and when not to wear your jewelry. Try to prevent situations where your jewelry would be exposed to hard blows. Prevent exposure to harsh chemicals, and especially avoid exposure to chlorine. Use only professional jewelry cleaners designed for everyday use. Our staff will advise you on the best products designed for your specific needs. Clean your jewelry often. Soaps, cosmetics, cooking oils and other contaminants quickly build up on your jewelry, and this will result in your jewelry looking dull and soiled.

Custom Design Services

Williams Diamond Center can help you design and create the jewelry item of your dreams.

Have you looked everywhere and still can't find the style or design you want? Or maybe you've always had a special design in mind but haven't been able to find it? We can help you create that special design from start to finish, bringing your ideas to life. Maybe you have a picture or even a description of a certain design; we will assist you in completing the final details. This information is forwarded to our design shop for a rendering of what your finished piece will look like. With your approval, a model will be made, and you will have the opportunity to accept, decline, or make changes, and you'll know the cost before the work is begun. Come see us at Williams Diamond Center, and take the worry out of creating a jewelry design uniquely your own.
