Ring Size Chart

How do I estimate my ring size?
Due to the incredible strength and durability of the material, Tungsten, cutting and shaping it is often incur lots of work and high technique (as compared to gold and platinum). Because of its unique characteristics and extreme hardness, it is very difficult to resize a tungsten carbide ring; therefore, great care must be taken when sizing your finger.

We suggest visiting a local jewelry store to get your finger sized accurately if you are not sure with your own ring size. Please inform the jeweler the approximate width of your ring. A person can wear up to half to almost one size larger for a band with larger width.

Alternatively, you can follow the procedure below to obtain your ring size. Sizes are expressed in American Ring Sizes. The ideal size will fit comfortably and be tight enough to prevent the ring from accidentally falling off. Before ordering make sure that the ring size is correct. Finger size changes with temperature and time of day. The best time to measure accurately is in the time of midday.

Step 1: Get a piece of an inelastic string or a strip of paper;
Step 2: Wrap it around the base of the appropriate finger;
Step 3: Mark the point on the string or paper to tighten up the loop, forming a complete circle;
Step 4: Measure the length from the starting end of the string/paper;
Step 5: Finally, determine your ring size from the chart below.
