SINRUIN started from a simple need: jewelry that could survive the night and still belong the next day.

I was making pieces for myself before going out—in Austin, Mexico City, New York, LA, Chicago. I didn’t want anything oversized or disposable. Nothing that only made sense under strobes and felt out of place after sunrise. I wanted elegance with endurance. Something refined enough to wear again, built for sweat, movement, and repetition.

I kept coming back to vintage ball chains. Stainless steel beads and tubes. Gemstones. Star beads. By breaking apart old necklaces, I began assembling new forms.

SINRUIN is shaped by people as much as objects. Dancers. DJs. OOMFs. Models. Himbos. IT Boys. IT Girls. Friends of friends. Lovers of lovers. Bodies in motion. People blending into each other in low light—sound making walls shake, sweat turning metal warm against skin.

These connections are the reality I know. Fluid roles. Shared space. Chosen family. Energy passing between bodies, looks, and hands. The jewelry lives inside that exchange.

This isn’t fantasy.
It’s documentation.

Each piece is assembled to order. Made to move with you. Made to be worn hard, then worn again.

Structure and sweat.
Night and after.

ASSEMBLED TO SIN.
