Jewelry inlaid with diamonds and precious stones is very beautiful, but because most of the inlaid gems are small particles and the inlay process is special, it is often easy to cause the inlaid gems to fall off when ultrasonic cleaning is used. Therefore, for jewelry inlaid with diamonds and precious stones, it is recommended that you do not choose ultrasonic cleaning.

2. Emerald jewelry

Emerald is a delicate and precious gem. Because most emeralds in nature have cracks, the surface of emeralds is often treated by oil immersion, which not only increases the luster of emeralds, but also fills the cracks on the surface of emeralds. Although the cracks on its surface have been filled up, emeralds can't be cleaned by ultrasonic wave, because the vibration and impact during cleaning will make the cracks of emeralds increase or even break.

3. All micro-inlaid borderless jewelry.

Although miniature inlay and borderless inlay are very delicate, their firmness is far less than that of pointed inlay and its inlay. Therefore, this kind of jewelry with weak inlay should not be cleaned by ultrasonic wave as far as possible, otherwise it will easily cause the inlaid gems to fall off.

4. Cracked or loose gem jewelry.

No matter whether the gem is cracked or loose, in this case, ultrasonic cleaning is absolutely avoided to avoid irreparable losses. If this happens to your jewelry, I suggest you send it to a professional jewelry repair office for reinforcement. For cracked jewelry, you must pay great attention when wearing it at ordinary times to prevent bumping and bumping.

5. Jade jewelry.

It is best not to use ultrasonic cleaning for jadeite. Use ultrasonic cleaning machine to clean jade for no more than one minute. If the cleaning time is too long, the fine cracks in jade will be amplified, and in severe cases, the jade will crack.
