It is not recommended to use ultrasonic cleaning machine to clean the Van Cleef & Arpels Frivole series jewelry. Here’s why:
1. ** Gemstone characteristics ** :
– ** Diamond setting risk ** : If the diamond on the Frivole series jewelry is a micro-inlaid or rimless inlaid style, the high-frequency vibration of the ultrasonic cleaning machine may cause the small diamond to loosen or even fall off after repeated cleaning. Because this vibration will have an impact on the robustness of the Mosaic, destroying the originally tight Mosaic structure.
– ** Gem rupture risk ** : If there are some gems with relatively low hardness and natural cracks or inclusions inside the series, such as emeralds, Opal, etc. (although the Frivole series does not necessarily have these gems, but there is a possibility), the strong cavitation and vibration generated by the ultrasonic cleaning machine may cause the crack expansion inside the gem or cause the gem to crack.
2. ** Metal material ** : Frivole series jewelry commonly used 18K gold and other precious metals, after a long time to wear or place there may be some subtle wear or deformation. The vibration of the ultrasonic cleaning machine may aggravate these originally not obvious problems, affecting the overall beauty and structural stability of the jewelry.
3. ** Process structure ** : Van Cleef & Arpels jewelry exquisite workmanship, Frivole series may have a unique design and complex structure, such as hollow, carved and so on. These fine parts may be damaged under the vibration of the ultrasonic cleaning machine, resulting in damage to the process details of the jewelry, reducing its artistic value and quality.
