DELECOE Sterling Silver Locking Earring Backs for Notched Posts — 2 Pairs 18K White Gold Plated, Hypoallergenic Secure

DELECOE Paris locking earring backs are compact 925 sterling silver replacement backs with an internal spring lock and 18K white gold plating, designed to secure diamond and pearl studs comfortably.

If you’ve ever worried about losing a precious stud, these DELECOE locking backs offer a discreet security upgrade without changing the look of your jewellery. Each set includes two pairs (four pieces) finished in bright 18K white gold plating over genuine 925 sterling silver. The mechanism is made to snap onto notched posts and stay firmly in place while remaining easy to remove when needed.

How do these backs attach to my studs?

The DELECOE backs use an internal spring lock that grips notched earring posts (single or double notch types). You press the two side buttons to open, slide the back onto the post until it clicks, and release to lock.

• Fits post diameters from 0.030 to 0.040 inches.
• Only compatible with notched posts — not for plain or threaded screw posts.
• Two-button press design for controlled on/off action.
• Compact dimensions about 0.28 × 0.40 inches (L × W).

Will these earring backs irritate sensitive ears?

DELECOE uses genuine 925 sterling silver plated with an enhanced 18K white gold layer to minimize skin reactions. The materials are nickel-free and described as hypoallergenic, which reduces common irritation risks for most wearers.

• Made from real 925 sterling silver base metal.
• Plated with a heavy 200% 18K white gold layer for durability and shine.
• Nickel-free finish to lower allergy potential.
• Smooth internal surfaces to reduce rubbing against the ear.

How secure are these locking backs for valuable studs?

Designed for everyday wear, the locking mechanism provides added retention compared with standard friction backs. The internal spring lock helps keep diamond and pearl studs from slipping off during daily activities, while still allowing deliberate removal.

• Internal spring lock clamps onto notched posts for firm hold.
• Two-button release reduces accidental detachment.
• Low-profile shape maintains the earrings’ aesthetic and balance.
• Available in both white gold and yellow gold colour options to match settings.

How do I choose the right backs for my earrings?

Measure your earring post and inspect whether it has a notch. These backs match posts between 0.030 and 0.040 inches and require a single or double notch. They are not compatible with screw-back posts or entirely smooth posts.

• Check post diameter with a caliper or jeweler’s tool.
• Look for a visible notch near the end of the post.
• Not suitable for screw-back or plain posts—confirm type before buying.
• Contact DELECOE support if you’re unsure about compatibility.

Who is this for: DELECOE Paris locking earring backs suit anyone who wears small stud earrings—especially owners of diamond, sapphire, or pearl studs who want stronger retention than standard friction backs. They are ideal for active wearers, frequent travelers, or anyone who prefers a low-profile secure back in either white or yellow gold tone. If your studs have notched posts and fall within the specified size range, these backs provide a discreet, comfortable way to protect valuable earrings while maintaining their original look.
