There are certain signs of quality that apply to almost all tungsten carbide rings, no matter what type it is or which method was used to make it. Specifically there are two signs that apply to almost all tungsten rings: invisible solder joints and porosity-free metal.
Invisible Solder Joints
Tungsten carbide rings that are not made from one method alone is usually assembled from some combination of cast, had-fabricated, die-struck, or electroformed components. In assembled tungsten jewelry, the bench jeweler usually solders the parts together. A precious metal alloy melts under heat and flows into the seam between two separate metal components, uniting them when it cools. Done well, soldering forms an invisible bond. The bench jeweler’s expertise makes the juncture both durable and invisible.
Soldering should not alter the look or durability of a tungsten carbide ring. However, improperly soldered joints, such as the area where a ring head joins to a shank, can display thin lines, cracks, or “blobs” of excess solder. Eventually, poorly soldered joints might discolor or separate.
Porosity-free Metal
Porosity shows up as defects in the precious metal of a finished jewelry item. In cast jewelry, the defects look like small pits. If it’s severe, porosity can detract from jewelry’s eye appeal. If it’s really severe, and this is rare, it can even threaten durability. A porous item might contain weak spots if pits, gaps, and other structural irregularities are large, numerous, or concentrated in one area.
Coppari Jewelry guarantees that only the highest quality of tungsten carbide rings are sold. You will never find a poor solder joint or porosity in Coppari Jewelry.
