I got the product in both, copper and silver. You get only one earring per color, I got the left one in both. There are stores which sell a pair (nevertheless, I would only wear one at a time). So, I don't know it these are all left or are given out randomly.
The earring didn't weigh much and was comfortable, after getting used to it.
I got a looot of compliments on this earring, people asked if they could take a picture, and where did I buy it. Never before have I realized how extremely uncomfortable it is to have 10 people staring directly at my ear.
You can buy this earring from here. These are on sale now, so hurry :)
