Shikaku[しかく] Silver925 / K18 Ring

Shikaku

What is universal beauty?

"What is the beauty that everyone thinks and feels beautiful?"

We have done a lot of design and have been thinking about it all the time.

Isn't the mathematically explainable "Surfaces" and "Lines" beauty just a universal beauty as we come touching with the world of origami and Bauhaus-like design?

Digital and hand work

In pursuit of mathematically explainable beauty, we needed the power of digital.

The shape of this ring is created by the orbit of a regular hexahedron (Cube) that keeps a certain angle.

The designer herself drew the prototype using CAD, a three-dimensional modeling software.

On the other hand, digital work alone does not make a ring that people can wear comfortably for a long time.

The level of completion depends on the work of human hands how to finish with good sensitivity.

Enjoy the texture of metal

If you look closely at the side of the ring, you can find delicate lines in a radial pattern.

Actually, these come out pattern when it is produced with CAD data and output with a 3D printer.

Generally, this pattern is erased and polished.

Rather, we thought that this accidentally created pattern was "what an interesting expression!".

Data traces on the side + light matte finish on the top

Of course, it is too rough to be a quality of jewelry.

At that time, Ayumi Maruyama, a craftsperson, has proposed to put a light matte finish on it after trial and error.

In addition, we decided to put another matte texture around the top of the ring.

 

The texture and the expression of metal are unique sensibilities and techniques that have been passed down to Japanese sword metalworkers.

In the MENTOSEN, each collection expresses the interesting texture of metal.

It is a new expression of metal that designers and craftsmen create by exchanging opinions.

 

It would be great to assemble the parts of gold

Only 5 square cubes are K18 gold.

"If you can assemble k18gold parts here, it would be cool ... but brazing would be quite difficult ...".

After making the platinum (or silver) and gold parts separately, it is a very difficult wotk to braze each one exactly.

To be successful, the following conditions must be met.

(1) The output of the 3D printer must be accurately modeled.
(2) There should be no distortion at the casting stage, and the pattern on the side should not disappear.
(3) Finally, the craftsman should braze exactly and finish it properly.

"Let's do it! Because it's cool!"

Ayumi, craftsperson, said.

And finally the Shikaku[しかく] ring was completed.

 

Inside is also a cube

Rings are generally flat on the inside.

However, this ring dared to leave the shape of Cube on the inside.
We wanted to express the interest of modeling.

Of course, the most important thing is to have a comfortable ring that people can wear all the time in a daily life.

Ayumi finished with hand filing leaving each shape, and each corner is smoothed.

Even though edges and surfaces are left, it will not bother you at all when you wear it.

In this way, it was completed a smart and interesting ring.

Reflection of light inside the ring

By leaving edges and surfaces inside the ring, when you look inside the ring, the light is reflected and moves.

A beautiful mirror finish that is easy to wear, while leaving a little inner edges and surfaces. It requires a highly careful handwork.

Hight level technique, careful work, sensitivity

Ayumi Maruyama was in charge of producing and finishing this Shikaku ring.

From a production efficiency standpoint, this ring must be a very inefficient piece of jewelry.

However, on the other hand, while she suffers from difficult productions, she seems to feel the joy of trying new things.

In the field of jewelery craftsmen which is dominated by male in Japan, she continues to work with reliable skills and new sensibilities.
