CoCr NF Threadless Attachment for Labret with Premium Zirconia

CoCr NF Threadless top for labret with premium Zirconia stone. 4mm stone, available in uncoated (steel) and 18K Gold PVD coated versions.

Compatible with threadless labrets with (0.8mm) "internal threading".

Material: Nickel Free Cobalt Chromium Alloy (CoCr NF) - It is widely used in the dental industry and for medical implants like knee and hip joints. The alloy we use is Nickel, Cadmium and Lead free which makes it REACH compliant.

Cobalt Chromium Alloys possess high corrosion resistance and amazing strength. It is very hard to break, bend, deform or even scratch. For these characteristics, it is the perfect material for tiny items.

At the same time, it has an appealing white color and shine that resembles precious metals like White Gold, Rhodium or Platinum. All this without plating or coating.

Gold PVD coating: real Gold is coated using a PVD (Physical Vapor Deposition) process. The jewelry is coated in a heated chamber under high vacuum. 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 (Gold) into tiny particles which are deposited on the jewelry. The result is a hardened layer, which is biocompatible. It can be autoclaved.
