Siwoms 14K Gold-Plated 925 Sterling Locking Earring Backs — 2 Pairs, Hypoallergenic Secure Spring-Lock for Notched Studs

Siwoms locking earring backs are secure, hypoallergenic 14K gold-plated replacements made on solid 925 sterling silver to keep notched-post studs in place comfortably.

If you own precious stud earrings, a dependable backing matters as much as the stone. These Siwoms replacement backs combine a spring-lock mechanism with nickel-free sterling silver construction and a thicker 14K gold plating to reduce irritation, resist tarnish, and prevent accidental loss. They’re designed specifically to work with notched posts (0.75–1.00 mm) and come as a practical spare set for everyday wear or travel.

How do these locking backs prevent my studs from falling out?

Each backing uses a spring-loaded clasp that squeezes closed around a notched earring post so the stud stays anchored until you intentionally release it. The dual-tab button gives a tactile lock and unlock action, making accidental slips unlikely while still allowing easy removal.

• Mega-grip spring lock for firm hold
• Dual-tab squeeze buttons for secure locking and simple release
• Engineered for notched posts to reduce slippage

Will these cause irritation or discoloration on sensitive ears?

They are crafted from solid 925 sterling silver and plated with a thicker layer of 14K gold, and they contain no nickel—commonly the culprit in earring reactions. That composition minimizes skin irritation and keeps the metal looking bright longer than thinly plated alternatives.

• Nickel-free sterling silver core for hypoallergenic wear
• 200% thicker 14K gold plating to slow tarnish
• Polished, smooth curves to avoid pinching or rubbing

Are these replacements compatible with my existing studs?

These backs are intended for studs that have a notched post measuring roughly 0.75–1.00 mm in diameter. They will not securely fasten to smooth (plain) posts, so check your earring stem for a visible notch before purchasing.

• Designed specifically for notched posts 0.75–1.00 mm
• Measures approximately 7 × 9 mm for comfortable coverage
• Not suitable for plain, un-notched earring posts

How durable are these backs, and what warranty is offered?

The Siwoms locking mechanism and heavier gold plating are intended to extend usable life and maintain appearance with regular wear. The product is sold with a lifetime exchange or refund policy to address manufacturing defects or dissatisfaction.

• Reinforced spring lock for repeated use
• Thicker gold plating for longer-lasting shine
• Hassle-free lifetime exchange or money-back warranty

Who is this for? These Siwoms locking earring backs are ideal for anyone who wears valuable studs—engagement diamonds, pearl studs, gemstone posts—or who wants a reliable spare set for travel and daily wear. They suit people with sensitive skin who need nickel-free options, buyers who prefer a secure locking action over friction backs, and anyone replacing lost or worn earring backs for notched posts. If you need comfortable, low-profile security without changing your studs, these are a practical, long-lasting option.
