The Benchmark Lifetime Guarantee ensures that your Benchmark ring is covered from any manufacturing defects. Benchmark’s rings are proudly manufactured in the U.S.A and have been for over 40 years. Manufacturing defects can occur (although rarely) within metals/materials and or stones. If your ring is registered and you have any issues related to manufacturing, Benchmark will repair or replace your ring free of charge. If your registered ring ever needs to be resized, refinished and or repaired (due to normal wear) there may be service fees assessed depending on the service type requested. This will be determined by your retailer at the time of your ring's assessment.
