Maintenance tips

There is nothing more beautiful and more resplendent than a brilliant jewelry in a thousand lights. Well maintained, a jewel becomes a precious family heritage. The St-Onge jewelry has thought of sharing some of its precious advice to help you better take care of your jewelry.

Wearing your jewelry on a daily basis means that you will have to take great care. Sweating, oil and salts produced by the body are major wear and dirt factors. In addition, the soap used daily is easily embedded in the hollow parts of your jewelry and remains glued there despite the rinsing with water. To make your diamonds shine as much as possible, we suggest that you gently clean your jewelry with a soft brush (a toothbrush, for example), a degreasing product and water, about once a week. This will reduce the accumulation of soap, dirt and dust. Following brushing, just rinse your jewelry with clear water and dry them with a soft cloth. However, this technique is not recommended for stones such as amber, pearl, coral, emerald, jade, lapis-lazuli, opal and turquoise.

If however you notice that your jewelry makes meshes in your clothes or if you see that a stone moves, it means that the claws (the small stems that keep the stones in place) have moved and are no longer as safe. If this is the case, we advise you to avoid wearing your jewelry and going to see us without waiting. We can advise you better in order to solve the problem.

Once a year, we suggest that you come and see us for polishing your jewelry in order to give them back shine and shine. We offer polishing and repair services to our atelier. At the same time, we can check if your jewelry is still in perfect condition, replace or repair stones or any damaged room, if that were the case.

Although gold and platinum are dense metals, their hardness is less than 5 on the hardness scale. This means that they can be scratched easily. To make your jewelry shine as much as possible, it is advisable to clean them gently with a soft brush and a degreasing product, at least once a week. This will avoid the accumulation of soap and dirt. Once your jewelry is cleaned, just rinse it with clear water and dry it with a soft cloth.

To clean your silver jewelry, nothing better than using a soft bristle brush, water and soap. Then rinse with clear water and wipe with a soft cloth. The fact of not wearing your silver jewelry will make sure they will tarnish and blacken. Many products are available on the market to clean your silver jewelry such as polishing laundry with anti-tenants, cleansing products and silverware mosses.

The diamond is the hardest stone with an index of 10 on the hardness scale. It can only be scratched by another diamond. You should also know that diamonds can scratch other precious stones such as pearls or metal. Take good care to store your jewelry individually, preferably in soft fabric pockets. Dirt or abrasives can also affect the radiance of a diamond. The use of corrosive chemicals can cause the degradation and loss of brilliance of a diamond. In order to always have shiny diamonds, gently clean the stones with a soft brush and a degreasing product. Rinse with clear water and dry with a soft cloth.

The pearls are alive and can last more than a hundred years if they are properly maintained. Culture pearls are soft and require special care. Their surface is porous and can easily deteriorate. They are particularly sensitive to chemical deterioration caused by skin and salts of the skin. However, the regular port of your pearls will help them stay hydrated thanks to the contact of your skin; They will thus keep their beauty and their brilliance. Avoid putting your pearls in contact with cosmetic products (perfumes, lacquers, alcohol, etc.) A collar of pearls worn on a daily basis should be reefiled once a year or as soon as signs of wear appear. You can clean your pearls by wiping them slightly using a soft cloth to avoid scratching their surface. When you do not wear them, take care to store them in a pocket of soft fabric.

The emerald

The emerald is probably the most delicate precious stone. Its crystallization peculiarities and its inclusions make emerald a very fragile stone. It is therefore necessary to avoid any type of impact, temperature variations (cold water/hot air, for example) and heat sources. It is important not to expose an emerald to detergents, which could modify its color and its finish.


Ruby is not a particularly fragile stone. It ranks just after the diamond on the hardness scale. Avoid contact with diamonds, shocks and friction.


Sapphire is not a particularly fragile stone. Like ruby, it also ranks second on the hardness scale, after the diamond. Avoid contact with diamonds, shocks and friction.

It is not recommended to use an ultrasonic machine at home. Only a professional can determine if his use is safe for your jewelry. If this type of cleaner is suitable for jewelry without precious stone like a golden rush, it is imperative not to immerse the precious stones or diamonds, especially if these contain fractures or inclusions.
