Rectangle with Round Diamond Push Lock Necklace
The Sophia ring features a radiant center diamond with delicate botanical-inspired accents, blending classic elegance with romantic charm.
The Rectangle with Round Diamond Push Lock Necklace centers on a 20mm 14K gold rectangle charm with a single round brilliant diamond. A geometric pendant with a classic brilliant cut.
The Piece
The rectangle is roughly 20mm long in polished 14K yellow gold, with a single 1/10 carat round brilliant diamond set into the gold surface. Round brilliant cut produces rapid scintillation against the rectangular gold form — quick sparkle rather than the slower flash of step-cut baguettes. The charm reads as a refined modern pendant with a classic diamond cut.

Frequently Asked Questions
How does the push lock closure work?
The push lock closure is a small mechanism on the charm that opens when you press it from the side. Once open, the charm slides onto the split chain or off of it; once closed, the chain runs through the charm securely. The motion is quick and one-handed once you've felt it a few times. The closure is engineered to stay shut during daily wear and to open only with intentional pressure — so charms don't fall off, but they're not permanently attached either.
Can I wear multiple push lock charms on one chain, or one charm on different chains?
Yes — both are part of how the system is designed. Multiple push lock charms can run on the same chain, stacked or spaced as you like. A single charm can move between chains of different lengths and styles to change the look. The push lock charms are also compatible with chains from outside the collection, as long as the chain is thin enough to fit through the push lock opening. The system is built around flexibility rather than fixed pairings.
How does the Rectangle with Round Diamond compare to the Rectangle with Baguette?
Both center on a 14K gold rectangle; the difference is the diamond cut. Round brilliant produces rapid sparkle and reads as a classic diamond setting; baguette produces broader step-cut flashes and reads architectural. Round brilliant pairs with rounder push lock charms in the collection; baguette pairs with rectangles and other geometric charms. Choose by visual character — classic sparkle versus step-cut architectural.
