Diamond Care



While diamonds are the hardest minerals, they still require some care to keep them looking their best and to protect them from loss or damage. The brilliance of any diamond depends on the amount of light that can enter the stone and reflect back to the human eye. However, the smallest deposit of grease on the surface of a stone can dull its reflection. Even a touch from a finger will leave a smudge of natural oil.

You are welcome to bring your diamond jewelry to Merkley Kendrick for a complimentary professional cleaning. We recommend you do this four times a year. We will also see that the stones are secure in their settings and we can make any necessary repairs during the cleaning process. Avoid using ultrasonic cleaners if your diamond has a serious crack or inclusion. The vibrations of these cleaners can enlarge such flaws.

To keep your diamonds clean between visits, mix some mild liquid detergent with water and apply with a soft, natural bristle brush. Rinse with fresh water and dry with a soft cleaning cloth.

A few words of warning: avoid cleaning your jewelry in or near the sink. If you do, make sure the plug is in. If you are using a brush, be gentle: diamonds can work loose from their settings if treated roughly. If you use hand lotion, wait for at least 10-15 minutes before putting your rings back on.

What could possibly scratch a diamond? Another diamond. To prevent such scratches, separate diamond jewelry in your jewelry box. Diamonds also can scratch other gems or jewelry, especially soft items like pearls. And even though diamonds are hard, they can be brittle, especially along thin edges. Try not to wear your diamond when it might be struck sharply, and if you have an especially thin cut, keep it protected. If you are traveling, use a secure travel pouch, which will keep individual pieces safely apart.
