Making a fully handmade ring is something very few companies do. Today, most rings, even diamonds rings, are made by wax casting metal and then polishing that metal. The results from cast pieces vary depending on the wax, the casting, the design, and the people doing the polishing work. Though great results can be achieved through casting, some people want a product made in a more traditional way.
A handmade ring is something very rare in today's world because of the time it takes to make it, and the skill needed to perform all to procedures properly. Handmade rings typically cost double that of the highest quality cast piece. However, when a master jeweler makes a handmade ring, there is an intangible beauty to it which is not possible to replicate through other methods.
After the top is formed wire is bent to form the shape of the ring shank. Then it is cut to perfectly fit the head. The piece is tested to make sure it's a perfect fit.
The final hand made piece is complete after many procedures taking a great deal of time. The advantages to this type of ring are in the quality of the metal work. there is simply no way to get a cleaner and more well finished piece. But is it worth the extra expense? That depends on ones appreciation for the tiny details, and for the work of a master craftsman.
