Tungsten Carbide TC850TM

Tungsten Carbide TC850 is the originally patented formulation and only available at licensed retailers. Nothing else compares to the structural strength and weight of TC850, which is solid, strong, scratch resistant and forever polished.

Tungsten Carbide can be found at many jewelers, most notably as the primary material in men's wedding bands. When used as the primary material in a wedding band, the ring appears with a lustrous dark grey hue often buffed to a mirror finish. The finish is highly resistant to scratches and scuffs, holding its mirror-like shine for years. It is possible to inlay other materials such as precious metals and woods.

Tungsten is a hard and dense metal known on the periodic table of elements as Wolfram. Tungsten Carbide is the combination of Tungsten with Carbon. It melts at an extraordinary 6,100 degrees Fahrenheit - the highest melting point of all metals. Tungsten is predominately used in high tech machinery, aerospace and high temperature applications. Once combined with carbon, the resulting material, tungsten carbide, is ten times harder than gold and has a hardness between 8.5 and 9.5 on the Mohs(1) hardness scale. In addition, TC850 is four times harder than titanium, twice as hard as steel, virtually scratch resistant and hypoallergenic.

How To Measure Your Finger:
1. Find a piece of string or strip of paper no wider than 1/2".
2. Wrap it around the base of the appropriate finger.
3. Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle.
4. With a ruler, measure the length from the starting end of the string/paper to the pen mark.
5. Use this measurement and the chart to the right to determine your ring size.
6. For more accurate measurement or if the finger is not available please click here to download and print our ring sizer and conversion chart. If the finger is not available you will still be able to find out the needed size using existing ring.

Tips For Measuring Ring Size:

Here are some tips to make your ring size measurement more accurate:
After sliding the ring sizer on, make sure it slides off fairly easily over the knuckle.
Don't measure cold fingers. This is when fingers are their smallest.
For the most accurate reading, measure the finger at the end of the day when the finger is the largest.
