Fine Jewelry Longevity Guide: Ultrasonic Cleaning Risks, Microfiber Polishing & Anti-Tarnish Storage

By Artisanal Silversmithing & Gemology Review Board

Preserving precious metal brilliance: safe cleaning solutions, which gemstones must never enter ultrasonic baths, and climate-controlled anti-tarnish storage practices.

Proper jewelry maintenance preserves precious metal luster and prevents accidental gemstone fracture or protective electroplate degradation.

1. Ultrasonic Cleaners: Safe vs. Prohibited Stones

Ultrasonic Cavitation Warning

High-frequency sound waves create microscopic cavitation bubbles that dislodge dirt from hard gems like diamonds and sapphires, but will shatter or fracture porous, fractured, or heat-sensitive stones.

Ultrasonic Safe: Solid 925 sterling silver, solid gold, platinum, untreated diamond, sapphire, ruby, cubic zirconia.
Never Place in Ultrasonic: Emeralds (causes oil filler bleeding), Pearls, Opals, Tanzanite, Turquoise, Coral, Lapis Lazuli, Amber.

2. Anti-Tarnish Silver Storage Solutions

Store sterling silver in sealed velvet pouches with activated carbon anti-tarnish strips to absorb ambient airborne hydrogen sulfide.
