Maintenance method:
1. When wearing a diamond ring inlaid with 18K gold, try to avoid contact with chemicals.
The primary color of 18K gold is golden yellow, while the white 18K gold we see is the color after electroplating. If articles containing chemical components (such as skin care products, hand sanitizer, vinegar, etc. ) frequent contact, the electroplating layer is easy to be corroded, exposing the primary color of 18K gold.
Therefore, please take off the diamond ring when removing makeup, and don't wear it for cooking, washing clothes or doing chemical experiments. Before doing these things, put the diamond ring gently in the jewelry box specially prepared for the diamond ring.
2. Avoid collision or friction between the diamond ring and hard objects such as metal.
Although diamonds are hard, they may also have cracks. 18K precious metals such as gold and platinum will also be scratched due to friction, or extruded and deformed, resulting in an unsightly diamond ring. Therefore, when wearing a diamond ring, it is not advisable to do strenuous physical strength or exercise. This can not only wear elegant taste, but also protect the diamond ring from being damaged.
3. Avoid placing the diamond ring in an environment that is too cold or too hot.
Metal expands when heated and contracts when cooled, so diamond rings are affected by temperature. Putting the diamond ring in an over-cooled or over-heated environment will affect the firmness of the diamond inlay, and may even make the diamond loose and fall off, causing unnecessary losses. Therefore, don't put the diamond ring in a place that is too cold and overheated, and try to avoid going in and out of places with large temperature difference between hot and cold, such as cold storage and bathroom.
4, often gently wipe with a soft cloth, but avoid cleaning with hand sanitizer containing chemical components.
There are too many things to do, and it is inevitable to touch a lot of things. Therefore, diamond rings are more susceptible to dust or oil pollution. You can gently wipe it with a soft cloth at any time, but don't use hand sanitizer containing chemical components to avoid corrosion of precious metals.
You can also go to the store where you buy diamond rings regularly and ask the staff to help you clean them and remove impurities such as dust and oil, which can not only avoid the damage of these impurities to the diamond ring, but also make the diamond ring look brand-new.
