Charleston’s Croghan’s Jewel Box Breaks Down the Silver Authenticity Test July 23, 2025 (0 comments)

Charleston, SC--Croghan's Jewel Box, a long-standing jewelry store known for its expertise in antique and modern silver, offers clear advice on how to determine whether silver is genuine sterling or plated. In a report by Southern Living, co-owner Rhett Outten outlines what buyers should look for before investing in silver jewelry or tableware.

Sterling vs. Plated: What to Know

Sterling silver is made from 92.5% pure silver. Plated silver, by contrast, uses base metals like copper or nickel with a thin silver coating. According to the report, silver plate is cheaper and eventually wears down, revealing the base metal beneath.

Outten notes that while sterling silver tarnishes, it's easy to polish. "Although sterling will tarnish, it is easily polished," she told Southern Living. "And often, it is rhodium-plated to preserve a high-polish finish."

Silver-plated items, however, can't be restored the same way and may require expensive replating.

Markings Are Key

Croghan's Jewel Box prioritizes sourcing sterling silver for its durability. Per the report, genuine sterling is usually stamped with "925" or the word "sterling." Outten warns that buyers should avoid unmarked items altogether.

The report also highlights that antique British sterling is often marked with a left-facing lion, while Scottish silver may carry a thistle stamp. "If it is not stamped, my advice is to stay away from the piece," Outten said.

Weighing the Differences

For vintage tableware, the distinction can be harder to spot. Per the report, estate silver plate was once triple-plated over copper, giving it a heavier feel. Outten notes that weight differences and stampings are useful clues, though consulting an expert or using online silver mark databases is often necessary.

Croghan's often advises customers to consider the type of item when making a purchase. Smaller sterling pieces, such as napkin rings and flatware, are more affordable, while larger silver plate items, like candelabras, may still be collectible due to their size and design.
