TK316 Stainless Steel used in fashion jewelry, is an alloy with a minimum of 10% chromium content by mass. It does not stain, corrode or rust as easily as ordinary steel, and it is also hypoallergenic. Thus, it is extensively used in heavy gauge-welded components, such as jewelry. Tusk 316 stainless steel is of the highest quality for jewelry products.
Bronzite is a member of the pyroxene group of minerals, belonging with enstatite and hypersthene to the orthorhombic series of the group. The color of bronzite is green or brown; its specific gravity is about 3.3–3.4, varying with the amount of iron present. The refractive indices and optic angle increase with iron content. Bronzite is sometimes cut and polished, usually in convex forms, for small ornamental objects. It often has a more-or-less distinct fibrous structure, and when this is pronounced the sheen has a certain resemblance to that of cats-eye.
