Titanium and stainless steel are becoming increasingly popular among the jewelry world. Both less expensive than gold, silver or platinum, it is no surprise the two metals are being used as alternatives for jewelry. People are looking for jewelry that will stand the test of time, after wearing such items day after day, which is why titanium and stainless steel are the new candidates.

When it comes to traditional wedding bands, most men opt for a simple band fashioned in gold or possibly platinum. Alternative metals that were once only used for industrial applications are edging their way into the jeweler's domain. Metals such as tungsten and titanium are prized for their durability and silver hues.

The tungsten element was discovered in the late 18th century, and its name is Swedish for "heavy stone." It was originally used as the filament of light bulbs, and now, when it's alloyed with carbon -- tungsten carbide -- it's used to make drill bits. Silvery tungsten looks a lot like hematite, and is renowned for its high luster, hardness and resistance to corrosion, which also makes it ideal for jewelry, such as wedding rings that may be subjected to wear and tear. The drawback: tungsten is so hard --10 times harder than gold and four time harder than titanium -- that it can't be cut with conventional tools like other metals can. Special tools that can cut through tungsten rings are available at hospitals.

Titanium and tungsten carbide are both very hard materials that have numerous practical applications. There are several advantages and disadvantages associated with each of these materials.

Hardness
While both materials are much harder than other metals, such as gold and silver, tungsten carbide is harder than titanium and is much harder to engrave, according to Titanium Kay, a jewelry company.

Ductile
Titanium is more ductile than tungsten carbide. Titanium will bend under high pressure while tungsten carbide will shatter under high pressure.

Weight
Tungsten carbide is much heavier than titanium. Tungsten carbide weighs over 90 percent more than stainless steel while titanium is 43 percent lighter than stainless steel.

Price
Titanium is typically cheaper than tungsten carbide because tungsten carbide has higher production costs. Tungsten is formed in conditions where temperatures exceed 6,000 degrees F.

Applications
Titanium has applications in the aircraft and aircraft missile production industries because it is a very strong but light material, notes the Los Alamos National Labs. Tungsten carbide is used in many applications, including grinding, machining and polishing.

Health
Unlike titanium, some people can have an allergic reaction while coming in contact with tungsten carbide, according to the New Jersey Department of Health & Senior Services. Exposure to the cobalt in tungsten carbide can lead to lung problems.

There are many reasons your ring may need to be resized, including you gaining weight, losing weight, injury or the ring being purchased in the wrong size. In most cases resizing a ring can easily be done by any trained jeweler. Soft metals such as gold, platinum, palladium and silver can be resized. However, if your ring is made of tungsten carbide it cannot be resized. Most rings will only be able to increase two sizes, as the metal will become too thin. If your ring needs to be sized down, this should also be sized two or fewer sizes down. Having your ring sized up or down only one size will give you the optimum outcome.

1.Take your ring to a reputable jeweler. If your ring was purchased with a warranty package, this may include free ring sizing for the life of the jewelry. If so, take your ring to the jeweler who sold it to you.

2.Place the ring sizer on the finger you plan wear your ring on. You may have to try two or three sizes to find the correct fit. Pick a size that is snug enough so that the ring won't fall off but still is comfortable to wear. You want to able to remove your ring when necessary. Your fingers will swell as the day goes on, si it is best to get your ring sized in the middle of the day, when your fingers are at their average size.

3.Inform the jeweler on any engravings in the inside of the ring. Oftentimes when resizing a ring the engraving will be ruined. See if your jeweler can resize the ring without damaging the engraving. If the jeweler is unable to resize the ring without damaging the engraving, ask the jeweler re-engrave the ring.

4.Pick up your ring once the jeweler has notified you that it is done. This process often takes anywhere between one to four weeks depending on how busy the jeweler is, and how difficult the ring is to re-size. Be sure to try on your ring to make sure that it is the proper size. Examine the ring to make sure it is how you left it and that there has been no damage to the ring.
