Tungsten Wedding Bands

We are excited to be offering the finest quality tungsten wedding bands at prices that are surprisingly low—sometimes less than half the price charged in jewelry stores. However, don’t confuse our low prices with inferior quality! All of our e- Wedding Bands tungsten carbide rings are made with the superior nickel-binder alloy instead of being made from pure tungsten or with the cobalt-binder alloy. Nickel-binder alloys are superior for several reasons:

Nickel-binder tungsten carbide is hypoallergenic, chemically inert and therefore will not oxidize, cause rashes, or irritate the skin.
We do not use cobalt as it can have an adverse reaction with the wearer’s skin, sometimes causing a rash.
Cobalt bonds with oils in the skin and leeches out of the ring resulting in oxidation. The oxidation appears similar to tarnished sliver, but cannot be removed by polishing or grinding. Nickel, on the other hand, does not bond with oil and therefore does not oxidize.
Many jewelers offer pure tungsten wedding bands which lack the hardness of tungsten carbide and can scratch quite easily. Some offer tungsten rings made with cobalt binder because it is cheaper to produce than nickel-binder carbide. We caution you against buying from a jeweler that doesn't specify that their tungsten wedding bands are made with the nickel binder alloy. Many stores don't list which alloy they are selling because they don't know which alloy they are selling. If they don't know, it is most likely cobalt alloy or pure tungsten which are cheaper and inferior to the nickel binder tungsten carbide wedding bands.

What is Tungsten Carbide?
Tungsten is a very hard and dense metal, mined from Wolframite ore and symbolized by a (W) on the periodic table of elements. It melts at an extraordinary 6,100 degrees Fahrenheit–the highest melting point of all metals. On its own, tungsten is vulnerable to scratches and damage just like any other metal, such as titanium and steel. Tungsten does not gain its extreme hardness until it is combined with a carbon alloy, transferring it into tungsten carbide (WC) with a hardness between 8.5 and 9.5 on the Mohs hardness scale. Tungsten carbide is four times harder than titanium, twice as hard as steel, is virtually unscratchable, and has been widely used for decades in industrial applications such as cutting tools, mining machinery, and rocket engine nozzles.

The unique formula of our tungsten carbide allows these rings to be both visually stunning and durable enough for every-day use. You are no longer required to constantly remove and replace your ring in order to protect its finish.

What is Black Tungsten?
With its rich color, lustrous shine, and sleek new designs, black tungsten is the hottest new look in tungsten wedding bands and is proving to be a popular choice for brides and grooms wanting wedding bands that express their individuality.

Tungsten carbide is naturally grayish in color, and because of its extreme hardness is a perfect base metal for physical vapor deposition (PVD) coatings. Under carefully controlled manufacturing conditions, and using this special process, the exterior surface color of naturally gray tungsten carbide wedding bands can be permanently changed to a rich and luxurious black. The interior is also coated except for a very thin line used for metal identification. The PVD coating on our Black Tungsten wedding bands not only produces a handsome wedding band that is similar to the color of onyx, but it improves the material properties of these wedding bands by extending their service life through high wear resistance and low surface friction. We have tested these Black Tungsten wedding bands for over a year now, and found that they are resistant to typical wear and scratching. Just like all of our other tungsten carbide wedding bands, sizing exchanges are free except for postage.

Can Tungsten Carbide Rings ever scratch?
Tungsten carbide can only be scratched or damaged by extreme measures, like abrasion from diamonds or corundum. Consequently, activities that would normally require the removal of conventional wedding bands for their protection can be performed without concern by the wearer of a tungsten carbide wedding band. While extremely strong and scratch-resistant, Tungsten carbide is a bit more brittle than traditional metals used in wedding bands. Fortunately, our outstanding warranty covers even the unlikely event of your tungsten carbide ring chipping or breaking! In addition, we warrantee the sizing, polish, and texture of our tungsten carbide wedding bands for life. If an e- Wedding Bands tungsten carbide wedding band ever needs to be exchanged for a different size, repolished, re-textured, or replaced because of chipping or breakage, all that is required is a copy of the original receipt and the ring. You will only be charged for return shipping and handling.

All of our tungsten carbide wedding bands are comfort-fit style, providing optimal comfort while wearing the ring and when putting it on or removing it. Because our tungsten carbide wedding bands are engineered to be maintenance free, we offer a lifetime warranty*.

e - Wedding Bands combines traditional precious metals with tungsten carbide to create a unique piece of jewelry with a style, polish, and texture that will last a lifetime. We offer tungsten carbide wedding bands with precious metal inlays of Sterling Silver, Platinum, Rose Gold, White Gold, and Yellow Gold. The tungsten carbide portion of the ring will maintain its original polish and luster for life, while the softer inlaid precious metals will eventually develop a textured appearance over time, creating an attractive contrast against the lasting polish of the tungsten carbide.

Can a Tungsten ring be cut off?
Can a Tungsten ring be cut off?
Yes! Please be aware that in any situation where there might be a medical necessity to cut off or remove a tungsten ring--for instance excessive weight gain, hand injury, etc.,--removing a tungsten ring doesn’t pose much more of a challenge than cutting through a gold or platinum wedding band. In our own jewelry shop, as in many other jewelry shops, we have a cutting tool designed for cutting titanium and tungsten wedding bands. In addition, tungsten bands can be fractured into pieces using vise-grip pliers. When we contacted our local hospital emergency room and asked if they were equipped to remove tungsten wedding bands in an emergency, they told us that most hospital emergency rooms are prepared to handle almost anything, and assured us that it would be no problem for them.

During our 30 years of jewelry repair experience, we've only seen a dozen or so rings that have been cut off in hospital emergency rooms, and in most of those cases the rings had been bent out-of-round and were putting painful pressure on the finger. Tungsten rings will not crush or bend out-of-round, so if you shut your hand in a car door or drop a heavy object on it, a tungsten wedding band is likely to fracture into several pieces and fall off your finger freely. You might be safer wearing a tungsten ring than a precious metal band! Nonetheless, check with your local jeweler or medical facility if you have concerns.

Sizing and Engraving
Because of the extreme hardness and durability of tungsten, tungsten wedding bands cannot be sized like gold, silver or platinum rings, so please take extra care in determining the proper size. Also, engraving a tungsten wedding band is possible but it is very faint and difficult to read. Because of this, we have chosen not to offer engraving on Tungsten rings.

e- Wedding Bands offers the best tungsten ring warranty available! Our tungsten carbide rings are engineered to be maintenance free, and we provide a lifetime warranty on the sizing, polish, textures, and against breakage. Under normal usage there will be little or no wear on both the polish and the textures of the tungsten carbide. Precious metal inlay material is excluded and is designed to exhibit a contrasting textured appearance after normal wear.

Our tungsten ring warranty includes lifetime ring size exchanges (tungsten carbide wedding bands cannot be resized conventionally due to their extreme hardness) plus we warrantee the polish and texture of our tungsten carbide wedding bands for life. If an e- Wedding Bands tungsten carbide wedding band ever needs to be re-polished, refinished, exchanged for sizing, or replaced due to fracture or breakage, all that is required is to return the ring with a copy of the original receipt, plus $35 for handling and return shipping. For inlaid tungsten bands, there is a small deductible depending on your inlaid metal: Sterling silver inlays require a deductible of $75 per ring. 14K and 18K gold inlays run $85 per ring, and platinum inlays are $135 per ring.

Please Note: Tungsten carbide rings are not indestructible. Therefore, e- Wedding Bands will void the warranty if a ring is altered in any way, including engraving, sizing, drilling, stone setting, polishing, boiling, cleaning with harsh chemicals, soldering, burning or showing evidence of obvious repeated physical abuse, such as striking with a hammer.
