We verify gemstones using a thermo-electronic analyzer. We hand polish our pieces. Ultrasonic cleaners can leave vintage jewelry looking unnatural. As the most reflective metal in the universe, we believe silver looks best with a little shine. Patina develops quickly on sterling silver, so we recommend hand polishing at least once a year. Or, if you prefer patina simply wear the piece and it will develop quickly. OR20 30 Day Satisfaction Guarantee Return Policy Customers outside the US are responsible for all customs and import fees.
