Job 42:11Then came there unto him all his brethren, and all his sisters, and all they that had been of his acquaintance before, and did eat bread with him in his house: and they bemoaned him, and comforted him over all the evil that the LORD had brought upon him: every man also gave him a piece of money, and every one an earring of gold.
Ex 32:2
Aaron answered them, "Take off the gold earrings that your wives, your sons and your daughters are wearing, and bring them to me."
Ezekiel 16:12-AV And I put a jewel on thy forehead, and earrings in thine ears, and a beautiful crown upon thine head.
Personally, I don't wear earrings, but if you can wear them with a clear conscious - go for it! But if your conscious isn't clear and you're looking for someone to help convince you or back you up on this topic - maybe you should think about it a little more.
