More information


Only top quality materials are used in the production of the jewelry. This includes brass, aluminium, stainless, acrylic rubber and leather. The brass is cut, shaped and soldered and then plated in a variety of quality finishes. The chains, bracelets and rings and certain other parts are also made out of brass. The aluminum is added to create a contrast in our two tone combinations. Our leather and rubber will not discolor on your skin. All of our stones are made out of glass that will not scratch. They are glued into place using specialized industrial glues. 


All of the finishes are among the best of the industry. They are extremely resistant. These finishes include; 10k gold, antique silver, silver, black, and bronze. They all have a special coating that protects their surface. 


All of the posts and wires on our earrings are hypoallergenic and among the best standard of the industry. We took the initiative to limit the nickel content in the finish of our pieces without compromising the quality of the work. We also eliminated the lead content in our solder wire; this favors a more ecological production. 


No special attention is necessary to preserve the beauty of the jewelry. No chemical products should be used to clean the surface of your pieces; simply use a wet or dry cloth to clean the surface if necessary. If you wish to have your jewelry retain its original beauty avoid wearing it in water and during physical activities that can damage your piece. The jewelry is of great quality and was designed for you to enjoy for many years to come.


Our jewelry is of the highest quality possible. Every piece was individually inspected, cleaned, and bagged to ensure it is free of any imperfections. Our product is fully guaranteed for a period of one year. In case of repair mail us the piece in question clearly indicating the problem.
