Good jewelry spot?

Hey all,

I’ve been living here for a while, and I’m trying to get a gold chain, nothing too extravagant or pricy, 10k or 14k gold. I went to a Cuban gold spot (jewelry king) in PlazAmerica but the prices seemed off. Either too cheap or too expensive, and not knowing the area, I’ve been researching online and I’m finding very mixed reviews. Some ppl say it’s fake gold, others say it’s real. Anyone have any suggestions on a decent spot to buy a real gold chain for decent price? Are all those stores in plazamerica selling fake gold?
