Titanium
I found that the FC is the hallmark for Francis Clark, a silversmith
Titanium!
A CP stamp on jewelry means commercially pure. If an item is titanium and has a CP stamp, it would mean commercially pure titanium. 90% titanium
The star is the makers mark and "ti" is titanium metal. What the ring is made of.
One can purchase a titanium wedding ring in wedding ring sellers such as Tiffany's. In addition, one can find and purchase a titanium wedding ring in online stores such as Amazon or eBay.
FC stands for , forged composite
Ring pulls on aluminum drink cans are made from aluminum. Titanium in both the ring pull and the can exists only as an impurity and is too minute to be extracted.
316L refers to the metal of the ring. That is a grade of stainless steel. L Stands for max .03% Carbon. TMA stands for: Titanium Molybdenum Alloy. It looks to me that the ring is made of 316L (stainless steel) coated with TMA (Titanium Alloy) and is made in China.
The best place to buy a titanium ring is in a jewelry store. It is not recommended to purchase the ring online due to the fact that titanium rings are very hard to resize. By purchasing in a bricks and mortar store, the purchaser is able to try the ring on for size to be sure of the fit.
Yes, titanium is one of the best nose ring materials, it is better than silver, gold, or surgical steel.
A real Casio G-Shock Titanium Frogman Dw8200 has a titanium ring around it. The fake Casio will be missing the titanium ring. Another way to spot a fake is that a Frogman was never created with 3 eyes.
