- •Sterling silver (.925) is an alloy of 92.5% silver and 7.5% other metals (usually copper), making it significantly more durable for everyday use.
- •Sterling silver is the standard for most jewelry, tableware, and decorative items due to its improved hardness and resistance to wear.

常见问题
Can I polish fine silver and sterling silver myself?
Yes, both fine silver and sterling silver can be polished. However, be very gentle with fine silver as it scratches easily. For sterling silver, use a silver polishing cloth designed for sterling silver, and polish gently to avoid removing too much of the metal over time. Avoid abrasive cleaners on both.
How do I know if my silver is fine or sterling?
Look for hallmarks or stamps on the item. Fine silver is often marked as '.999', '999', or 'Fine Silver'. Sterling silver is typically marked as '.925', '925', 'Sterling', or 'Ster'.
Which type of silver tarnishes more?
Both fine silver and sterling silver can tarnish. Tarnish is a chemical reaction with sulfur compounds in the air. Sterling silver may appear to tarnish more noticeably because the copper alloy can react and contribute to the discoloration. Proper storage in airtight bags and regular cleaning can help prevent and remove tarnish for both types.
