High Quality Jewelry
Freyja Piercing offers nothing but the highest quality jewelry in the industry. For the initial piercing we use only ASTMF-136 implant grade titanium, niobium, or solid 14k/18k gold. We have a large selection of jewelry to choose from, if there is something you're looking for that we don't have in stock, we are more than happy to custom order it from any of our suppliers.
We carry BVLA and Anatometal Jewelry.

Chemically, gold is unaffected by air, moisture and most other corrosive reagents, which makes it well suited for use in coins, jewelry and as a protective coating on other, more reactive, metals. However, it is not chemically inert.
Whereas most other pure metals are gray or silvery white, gold is yellow. This color is determined by the density of loosely bound electrons. Common colored gold alloys; a mixture or metallic solid solution composed of two or more elements, such as rose gold can be created by the addition of various amounts of copper and silver. Alloys containing palladium or nickel are also important in commercial jewelry as these produce white gold alloys.
Because of the softness of pure gold, it is usually alloyed with base metals for use in jewelry, altering its hardness, melting point, color and other properties. Alloys with lower karatage, typically 22k, 18k, 14k or 10k, contain higher percentages of copper or other base metals in the alloy. Karat is the unit of purity for gold alloys which is measured as twenty-four times the purity by mass. Therefore, 24-Karat gold is pure, 18-Karat gold is eighteen parts gold six parts other metal, 12-Karat gold is twelve parts gold twelve parts other metal, etc.
Titanium is another common metal considered suitable for body jewelry; all 38 alloys are compliant for implant. Though there are many commercially used grades of the material, the only recommended for use in piercing jewelry by the APP is titanium (Ti6Al4V ELI) that is ASTM F136 compliant. This is widely used in the industry since it best meets our needs. Because of its nickel-free content, titanium rarely causes allergic reactions. It is highly resistant to corrosion and is less likely to react with bodily fluids. Being a lightweight metal (around 60% the weight of stainless steel given the same volume), makes titanium quite appealing for a piece of body jewelry, especially larger sizes. Aesthetically, titanium has another draw; it can be anodized in several brilliant colors.
Niobium is a metal that actually resembles titanium in certain aspects, one of which being that it does not react with body fluids. It is heavier, and more expensive to produce than titanium; you won’t find as much body jewelry created with the metal. If niobium is not used in its purest form possible, it can lead to allergic reactions to the material. Niobium is another metal that can be anodized for colors similar to those produced with titanium. Because Niobium is elemental, it does not have a rating with ASTM. Since nothing is added to the metal, it eliminates the need for a rating, and this is part of the reason it is so biocompatible.
ASTM stands for American Society for Testing and Materials and their standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Their criteria for an implant grade rating is based on the presence or lack of presence of certain elements.
