Titanium Jewelry : The Fashion Jewelry IndustryAre you buying a men’s titanium ring as a gift? Are you thinking of getting titanium rings for wedding? Do you know the true meanings behind the metal as jewelry? Here is some general information for making such a decision.

Many people, including myself, heard of Titanium for the first time when either a military aircraft or a human joint substitution was mentioned. It seems like jewelers are just running out of new ideas for making new lines of jewelry. Yet, titanium jewelry is one of the fastest growing jewelry industries nowadays and there are actually plenty of justifications to the popularity.

Most people misunderstand that Titanium the element Ti on chemistry periodic table is a strong metal. In fact, the metal alone is not hard enough for most of the purposes it serves today; it is the alloy that produced from it that offers the superb strength and resistance to heat. Also, Titanium is not considered as precious metal like silver, gold or platinum.

So what makes Titanium so attractive? The most obvious reasons are the superior tensile strength and hardness. A particular grade of Titanium, 6.6.2, composes of a particular mixture of titanium, aluminum, vanadium and tin is used in many industrial applications such as aerospace. Therefore, the jewelry made of such (aircraft grade) Titanium like wedding band rings have no problem of being used every day, unlike gold or silver which can be scratched easily. In addition, the fact that Titanium wedding rings are much harder and more durable than gold and silver makes it a perfect candidate for symbolizing the eternity of love in a marriage.

Besides traditional uses in wedding, Titanium also possesses various properties that allow it to become popular in the fashion jewelry industry. For example, tension set diamond rings in the form of an open circle with a diamond mounted in the openings is one of the most sought after designs that not many metals can be used in. Also, Titanium reacts with different chemicals in electrolytic solutions and turns into different colors such as green and blue, a process called anodization. This makes Titanium Rings much more versatile when it comes to fashion. Finally, Titanium can also be combined with traditional metals like gold and silver in the form of inlay. Men’s titanium rings with gold or silver inlay are created by bombarding the ring in a vacuum environment with a gold or silver atom beam in an angle that the metals adhere to the ring evenly.
