An admiral ring would be real gold. It would also not have any hearts or keys hanging from it. This is not a real antique. My grandfather was an admiral in 1963 and he told me the story of his ring. It was real gold and worth a LOT.
I found this info. while searching the internet. Also, many people use these types of rings as purity or promise rings. The key symbolizes guardianship and knowledge. The key is a symbol of opening and closing powers. It represents curiosity, knowledge, initiation and mystery. The meaning of the key depends on its color. Silver keys symbolize temporal power. A gold key represent spiritual power. Two keys crossed in saltire is the emblem of St. Peter. He held the keys to the gates of heaven, and this emblem is part of the insignia of His Holiness the Pope. They occur in many ecclesiastical coats of arms but also in the arms of regular families. In Christianity the key to heaven is the power to absolve sin. It is a sign of faith and fidelity. The key is the spirit opening the gates of heaven.
The lock has long been a powerful heraldic symbol of protection. It represents the confidence of your safety and the next day.
Together lock and key symbolizes the obstacle and the solution. They show that there's no unsolvable problems and there's always a way out of different situations.
Love information like that. I'm a knowledge Junky and having that little bit turns this ring into a conversation piece :) Thanks for the lesson. I was planning on bidding, hope you didn't blow my chance at winning :) just kidding, hope it gets a nice winning bid it's a nice ring.
