Vintage Gold Mariner’s Chain Bracelet

Lovely one person piece that was almost never worn. Looks new. Gorgeous Mariner’s link that lays and moves beautifully. This might 10k gold plated but the original owner can’t quite remember and I suspect it may be gold tone. One of the earlier lobster clasps - dates to the 80’s. Very nicely made - I can find no mark. There is something on the clasp that I cannot make out even with the loupe - might be nothing. I suspect this is an old unmarked high quality costume piece. ~7.25” long - please see all pics for best idea of size and condition. Excellent vintage condition with no significant wear. Wear alone for a minimalist look, or layer ‘em up! Style Profile: vintage flat gold mariner’s chain 80’s minimalist layering maximalist feminine classy grandmacore coastal flowy romantic soft
