How much could this jewelry be worth?

So i have some jewelry I got from my grandmother. One thing is a 14K gold bracelet. It kinda looks braided and it about 6.5 inches long. The next is a lady bug bracelet. The chain itself is gold and it looks like the ladybugs have gold enamel on them. They're pink. Idk if it's real gold though so if anyone could help me with that...Lastly I have a cross. It's heavy and has what look like diamonds.pearl, and amethyst. The chain is real silver but im having doubts if the rest is real seeing as it's magnetic. Could someone possible help tell me waht any of this is worth or if it's real?
