Titanium 6AL-4V-ELI, ASTM 136

Titanium is ideal for both initial body piercings and healed piercings as it is compliant with the EU Nickel Directive introduced in Europe in 2001. Because of its virtually 'Nickel Free' content Titanium has become one of the preferred materials used in piercing jewelry within the borders of the European Union.

Grade Ti6AL-4V, ASTM F136 is the specification for the alloy to be used for surgical implants. The color of titanium is a silvery metallic white. An anodization process allows the metal to have a variety of pleasant colors. The color of the anodized titanium pieces depends on the pressure applied during the polishing process. Titanium is only half the weight of steel and twice as strong. Titanium can be sterilized in an autoclave.

Black PVD Coated

The black coating is realized by a PVD process (Physical Vapour Deposition) and it can be applied on a variety of metals.

The jewelry is coated in a heated chamber under high vacuum. The electric voltage applied will form a plasma in the chamber and the introduction of various gases produces an ion bombardment.

This bombardment atomizes the cathode material into tiny substances, which are deposited on the jewelry. The result is a hardened layer, which is biocompatible. It can be autoclaved.

Premium Crystals

WHAT IS PREMIUM CRYSTAL?

Premium crystals are man-made gems manufactured in Austria. In 1892, Daniel Swarovski invented a machine for making precision-cut, beautiful, high-quality lead glass crystals using quartz, sand, and minerals. The exact proportions of these raw materials have remained a company secret. This specialized manufacturing process ensures the highest possible degree of precision which produces brilliant crystals. For five generations, the Swarovski family has continued the tradition of making the most recognized crystals in the world out of their factory in Wattens, Austria.

WHY ARE PREMIUM CRYSTALS MORE EXPENSIVE THAN GLASS?

The method of production and processing of raw resources are important factors in the quality of finished crystals. Swarovski uses only the finest materials to fashion faceted lead glass that is known around the world for its brilliance and value. Superior production, materials, cutting, and polishing are what set Premium crystals apart from other glass works. According to Swarovski, “Cutting hard materials such as crystal and gems, in such a way that they have a hundred identical facets in several directions, is a very complicated task; each direction of the reflected light must first be calculated by computer, then this has to be simulated in 3D, optimized and finally converted into control programs for complex machinery.”
