You will not regret it by forging a ring.


The commitment of TANZO. (TANZO = Forging in Japanese)

Hold in your hands a stunning “masterpiece” ring that has been crafted with painstaking attention to detail by skilled artisans at TANZO, a forge of forged rings that has a long-standing reputation since its establishment in 1955. TANZO uses the traditional forging method that has been passed down in Japan since ancient times, and which is also used in the crafting of Japanese swords, to guarantee a ring-making process that is flawless and leaves no room for any regrets.

In the world of ring crafting, there are two primary methods - the “casting method” and the “forging method.” However, TANZO, the ring maker, exclusively employs the rare “forging method” to create its products. This method involves hammering metal meticulously over time, resulting in rings that are extremely durable and resistant to scratches. Each ring produced by TANZO is a product of dedicated forging, with skilled artisans investing time, effort, and care into crafting each piece. This commitment to quality reflects traditional Japanese craftsmanship, giving each ring a distinct “flavor” that is the hallmark of artisans who spare no effort.

At TANZO, every ring is unique and made-to-order, which means you can let your imagination run wild. You get to choose from a variety of materials, including six types of gold and platinum. You can also decide on the shape, surface finish, and number and size of diamonds for your ring. Birthstones and engravings are customizable, and you can add motifs or portraits to make your ring unique. If you’re not sure what you want, you can explore options and get inspired by looking at our albums and samples. At TANZO, we value comfort and pay attention to detail. That’s why each ring is finished with an inner round finish, ensuring that it fits comfortably and feels great on your finger. Don’t hesitate to consult with us if you have any questions or need help coming up with the perfect design.
