Modern Design Custom Jewellery & Jewellery Remodeling

At Shinko Studio, our custom jewellery and remodeling services combine the design expertise of our original brand, MENTOSENwith modern aesthetics and exceptional craftsmanship. We create unique, high-quality jewelry tailored exclusively for you.

Designs for Everyday Life

Our design philosophy is rooted in Bauhaus-inspired modern design.

Jewellery should be simple, functional, and fit naturally into everyday life.

We design pieces that are not overly eccentric, yet carry a distinct touch of originality.

– A Note –

It is not possible to directly create a custom-made piece based on an AI-generated design.This is due to intellectual property considerations and the fact that such designs often present significant challenges for actual jewelry manufacturing.
You are welcome to bring it as reference material.

Designing in 3D

Our designers use advanced 3D CAD software to bring your ideas to life.
This allows us to create beautiful, three-dimensional designs with precise lines and smooth surfaces.
During the design phase, we can provide 3D-printed models for you to review.
If you live far away, we can send you these 3D models or CAD images. For remodeling projects, we may ask you to send us your original piece first so we can measure the gemstones and assess their condition.

For clients living overseas：We accept orders only if you are able to visit our studio in person at least once. If we ship the final piece to your country afterwards, please note that international shipping fees, customs duties, and local taxes will apply. Thank you for your understanding.

See Your Design with 3D-Printed Models

When we present our design concepts, you can view and feel them through 3D-printed models.
For those who cannot visit the studio, we can share 3D rendering images or multi-angle structural views (3-view or 5-view diagrams) to help you visualize the final piece.

Exceptional Craftsmanship

Your jewelry will be crafted by highly skilled Japanese artisans, including certified First-Class Jewelry Technicians.
We propose new designs born from technical expertise, such as intricate stone settings and the rendering of matte metal textures.
