Not sure of the length exactly but it wouldn't fit in my daughter.

Yes and no . Some companies will put say 14925 Italy. That means its plated any type of Jewelry you see 925 on is not soiled gold its plated. The difference is the company. We have all bought a peice of jewelry a week later it was full no shine. They aren't interested in return customers. Yes the gold is real. The way a company that is absolutely sure they want return customers is when they plate the item they use a high karat gold like 18k and apply it in very thin layers. Where as the one's that turns quick they use a lot lower karat and use just a few layers so as the layers wear off it turns dull. Mirabella or lifetime jewelry reputable places. Again the gold is real but they might put 20 layers on a piece of jewelry of 18kt gold. It stays bright and looks good really as long as you want depending upon how you were it, plus your saving 75 percent or more and no one knows unless you tell them.
