How does the push lock closure work?

The push lock is a small clasp built into the charm. Press the side and it opens, so the chain slides in or out, then it closes to hold the chain securely. It's quick and one-handed once you've done it a few times, and it stays shut through daily wear, opening only with intentional pressure.

What makes the heart lock different from the other push lock charms?

The heart is one of the few push lock charms with a sentimental shape and full diamond detail: about 1/5 carat of natural diamonds set across a 25mm heart in solid gold. Pair it with the split chain you choose. It works alone as a focal piece or layered with plainer charms.

Can I wear more than one charm, or move a charm between chains?

Yes. The push lock system is built for it. Run several charms on one chain, stacked or spaced, or move a single charm between chains of different lengths and styles. The charms also fit most thin gold chains, as long as the chain passes through the push lock opening.

The Push Lock Necklace Edit

One chain, many locks. Choose a lock, choose a split chain, and change it whenever you like.

The push lock is where the design begins. Choose a round, oval or wide oval, a heart, a long hexagon, a padlock or a paper clip shape. Each lock is 14K gold, and several carry natural diamonds along the outline or set into the surface. The closure is built into every lock: press it and it opens, so it attaches to or comes off a chain without tools.

Choose the split chain your lock threads onto: paper clip, rolo or curb, or the paper clip bracelet. Each chain shows its photo and price, and it is added at checkout. Already have a split chain? Choose that option and order the lock on its own. Shorter chains (16 to 18 in.) wear the lock near the collarbone; longer chains (20 to 24 in.) let it hang lower for layering.

A split chain holds more than one lock. Wear two side by side, mix a diamond lock with polished gold, or clip on a pendant with a hinged bail. The chain stays the same; the locks and charms change with the day or the year.

Start with one lock and one chain, then add as the moments come. Wear a single lock on its chain for every day, two locks across two chain lengths for evening, or pair a lock with a solitaire or lariat necklace for a layered look. Every lock and chain works with every other, so each new piece adds to what you already own.

Frequently Asked Questions About Push Lock Necklaces

You choose. On each push lock page, pick the split chain your lock threads onto: paper clip, rolo, curb, or the paper clip bracelet. Each one shows its photo and price, and it is added to your order at checkout. If you already own a split chain, choose "I already have a split chain" and order the lock on its own.

The paper clip chain (20 in.) has long, open links and suits the oval and paper clip locks. The rolo chain (20 in.) has round, dense links that pair well with round and heart locks. The curb chain (18 in.) is flatter and carries the larger locks well. The paper clip bracelet (7 in.) puts the same lock on your wrist.

Yes, if it is a split chain: open at both ends rather than a closed loop with its own clasp. The lock closes around both ends, so a standard clasped chain will not work. If you are not sure, send us a photo of your chain and we will check it for you.

Yes. A split chain holds more than one lock, and pendants with a hinged bail clip on as well. Every lock and chain works with every other, so you can start with one piece and build from there.

Yes. The diamonds on our push locks are natural, and each product page lists the total carat weight and quality. Every lock is solid 14K gold, with no plated parts at the hinge.

Push locks and split chains ship in about four business days, fully insured with tracking. The estimated ship date shows on each product page.

Fine jewelry may be returned within 14 days of delivery for store credit. Every piece is also covered against manufacturing defects for six months. The Warranty and Returns tab above has the details.
