Because the material of the ring is 18K gold, as the most common diamond-encrusted material in the market, if you don't maintain 18K gold in your daily life, the ring will turn yellow. The reason why the ring turns yellow is that 18K gold is made of 75% gold and other metals, which will turn dark yellow when worn for a long time. This is a normal phenomenon, not a quality problem.

When the ring turns Huang Shi due to long-term exposure to chemicals, users can go to the jewelry store for polishing and maintenance to restore the original white color. If it is an electroplated ring, re-electroplating the complementary color in the jewelry store can also restore the original white color of the ring.

2. Avoid wearing accessories for washing and bathing. Pearls are afraid of acidic substances and cannot touch detergents.

3. Avoid chemical gas and environmental pollution. For example, all jewelry should avoid sulfur, and emeralds should avoid spraying pesticides.

4. Avoid putting multiple pieces of jewelry together. For example, hard diamonds can easily scratch other gems, so hide them separately after use and put them in separate boxes.
