First we take an old silver quarter. We hammer it and polish it until it looks like gentle waves of silver. Then we engrave an intricate compass on the top. The result is a very unique necklace that will last forever. The back side remains unhammered to show that it is a coin. The quarters used are minted before 1965 because those ones are made of silver. Our thinner chains are 5mm thick and our thick chains are 7mm thick. They are made of stainless steel and are very strong and smooth. The thick version is heavy and perfect for guys.
