Each piece is assembled to order.

Made to move with you.

Made to be worn again, day or night.

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. Shared space. Chosen family. Energy passing between bodies, looks, and hands. The jewelry lives inside that exchange.

This isn’t fantasy.
It’s documentation.

ASSEMBLED TO SIN.

Necklace lengths are measured from clasp to other end of necklace in inches. Snake chains come in three sizes only: 15.5 inches (smallest used in hugging star), 17.5 inches (medium length uses in shooing star), 19.5 inches (large length offered in select styles).

Measure your neck with a tape measure or a favorite necklace using a ruler.

Though stainless steel is durable, protect your piece by clasping it securely and never tugging to remove. The star is made of thick ceramic so though it may survive a drop or two, try not to slam it on the ground!

These necklaces have been tested by my DJ friends and ravers. No complaints. But they do love to wear them frequently and constantly.
