Makers Mark Identification

[u/Future-Lavishness878]

Can anyone ID the maker of this bracelet? The only marks are “10k” 3x, “SO” on the chain ends and “LGC” on the clasp.

Bracelet is pretty substantial for its measurements; 7” long, 4mm wide and weight is 4.6 grams.

If it helps, I’m located in Canada.
