Make a ring that is uniquely yours with us today!

Choosing Materials, Widths, and Design

Starting with design consultation, we will walk you through our samples and guide you in choosing your preferred material, ring width, designs, and finishes for your rings.

Engraving

You may opt for free engraving methods like metal stamping which comprises alphabets, numerals, and original icons. Before working on your actual ring, we will provide you with a silver bar to practice engraving.

Shaping

Once engraving is completed, you will start shaping the metal bar into a ring. This process requires strength and support, hence you and your partner may need to help each other out.

Soldering

After rounding, you will solder your ring under the guidance of our craftsman. Our artisans will solder all platinum rings as they require a license to operate the burner.

Texturing

Depending on the design of your ring, texturing or lathe machine-cutting will come next. If you chose a plain finish, polishing will be done at this stage.

Sanding & Polishing

At this stage, you will work with several tools to smoothen and polish the surfaces of your ring.

Completion

Your ring is completed! If you wish to set a diamond or birthstone on your ring, our artisans will work on them at the end, and you can take them home on the same day!

TEXTURES & FINISHES

Plain / Textured Finish

In addition to the standard plain finish, you can choose for free the popular hammer finish that brings out the craft aesthetic.

Plain

+¥0
A timeless classic. The mirrored finish may look simple, but a lot of work goes into achieving a beautifully polished look! The sense of satisfaction lies in watching your jewelry shine after repeated sanding and buffing. The color of the gold is emphasized when matted.

Hammered

+¥0
Akin to shimmering water surfaces, this texture is created with a round-tipped hammer. Every piece of jewelry has a unique pattern as it is formed depending on how one wields the hammer. A matted hammered surface gives it a subtler appearance (this is also the most popular texture!)

Foresta

+¥0
Reminding one of the forests and trees, foresta texture is achieved using a hammer with a flat tip. A wider ring gives a closer resemblance to the tree trunk. Polished or matte, this texture is perfect for those who want a nature theme wedding band.

Snowflake

+¥0
Resembling a snow flurry, this texture is impeccable in platinum but also looks glamorous in gold. Polish your ring for an emphasized look or mattify for a gentle glow.

Frost

+¥0
Like frost forming on a winter window, this texture is created using a specially crafted hammer. Each ring is truly one-of-a-kind, as the pattern naturally varies with the hand of the maker. Choose a polished finish to highlight the texture, or opt for a matte surface for a softer, more subtle effect.

Stella

+¥0
“Stella” means “star” in Italian, and true to its name, this texture evokes the enchanting shimmer of a starlit sky. Pair it with gemstones of your choice to create a truly personalized and radiant design.
Side Mill and Hammer Texture

Side Milgrain

+¥11,000
After the hammer finish, milgrain is applied to both ends of the ring.
* Compatible with ring width from 2.0mm.

Senban Finish

By using a lathe machine, craftsmen shape the ring into a uniform, beautiful, and luxurious-looking ring that evokes a custom-made ring.
* Compatible with ring widths up to 3.5mm. For widths larger than that, please contact us in advance.

Oval

+¥5,500
The ring’s surface is precision-machined to achieve a classic Court Shape profile. Expert craftsmanship creates a softly rounded silhouette and an exceptionally smooth, comfortable fit for everyday wear. With its timeless design and flawless finish, this wedding band beautifully showcases the precision and artistry of our master craftsmen.
Shape

Mare

+¥5,500
By machining the ring toward the center, a smooth, gently tapered silhouette is created. Inspired by the gentle curves of ocean waves, this design features a subtle concave profile that adds elegance and comfort while enhancing the ring's refined appearance.
* Compatible with ring widths from 2.5mm to 3.5mm.
Shape

Alps

+¥5,500
By carefully carving both sides of the ring, a raised center ridge is created, giving the surface a sharp, mountain-inspired profile reminiscent of the Alps. The precisely symmetrical finish creates a clean, structured look, making this ring an elegant choice with a refined and sophisticated appearance.
Shape

Line

Line
