Thanks for reaching out Kelsie, I am so glad you found us!
The "CH" letters. most likely stands for "chapa," which is Spanish for plated. In many Latin American countries & on imported jewelry pieces, a stamp like "14kt CH" means the jewelry is made of a base metal (like brass or copper) but layered with a thin coating of 14-karat gold.
Because the bracelet is heavy and marked 14kt, the best way to test whether it is solid, hollow, or heavy plating is to have a professional jeweler test it.
Kelsie, you can also perform a quick magnet test at home, to do this test you will need a strong neodymium magnet (rare-earth magnet), as standard refrigerator magnets are too weak.
