[About special rings and wedding rings]

Thank you for finding the "dzdz / zuzu" ring.

For eight years, we have been making simple rings that blend into everyday life.

We aim to create simple and elegant rings that are comfortable to wear and can be worn beautifully even as the wearer becomes older and grandparents, and that are not bound by trends of the times.

Each ring is handcrafted by the artist himself from start to finish.
When repairing, we do not replace the product, but rather use the original material to thoroughly repair it (we also post repair progress on social media).

I'm glad you like this concept.

This is a ring that I, the maker, have a special attachment to, as I am also married and have been using it ever since.
If you have any questions, we will answer any questions you may have, from construction to usability.

*Only lump-sum payments are accepted. If you wish to pay in installments, revolving payments, or bonus payments, please contact your card company in advance to see if changes can be made after payment.

[About the material]

The material used is 18k gold.
*18K gold = 75% gold + 25% other metals


Compared to silver, 18k gold is more corrosion-resistant, resistant to oxidation, and requires no special care. 18k gold is also about 1.5 times heavier than silver, making it a heavy, substantial precious metal.

18k yellow gold that blends well with the skin

The 18k yellow gold we use is a soft reddish yellow. It is an elegant color that is not too flashy and goes well with Japanese skin tones (different from pink gold).

Even customers who have not considered glamorous yellow gold at other stores often choose yellow gold for their special rings at dzdz.

Grey-toned 18k white gold

18k gold contains 75% gold, and the remaining 25% can be mixed with various metals to create a white color (18k pink gold is an example, although we do not carry it in our store).

18K white gold has a deep, brownish silver color. It is sticky and flexible (slightly soft), and is more susceptible to scratches than yellow gold.

We often hear that white gold "rusts easily," but this is because many rings are plated to make the white gold look whitish, and over time the plating peels off, revealing the color of the base metal. Our shop does not plate the rings, so you can enjoy the natural color of the base metal.

A combination of two ingredients

This ring is made from a combination of two materials: 18k yellow gold and 18k white gold.
The atmosphere changes depending on whether you use yellow or white as the main color.
It is also popular for couples to swap out the main material. This ring is recommended for couples who want different colors or are unsure about which color to choose.

Although the ring has a simple shape, by combining the color, thickness, and engraving of the base metal, you can create a ring that is unique to you two.

[Regarding the shape and width of the ring]

The shape is oval.
Available in six widths: 2.0mm, 2.6mm, 3.2mm, 3.8mm, 4.4mm, and 5.0mm.

Learn more about shapes

This is an oval ring that is rounded on both the outside and inside.
The soft roundness makes it a comfortable shape that fits comfortably into your everyday life.
You can wear it with peace of mind when holding hands with someone you love or touching something important.

The ring is not too high so that it does not interfere with other fingers when worn, so you can wear it without worrying about it.

K18 Classic Oval Ring / 2.0mm

The width of 2.0mm is delicate for a wedding ring.
Recommended for those who want to enjoy layering it with an engagement ring.

One male customer who visited our store requested a 2.0mm ring because he was not used to wearing rings and did not want it to stand out. However, when he tried it on, he found that it gave him a feminine impression and made him stand out even more.

Please take your time to think about it, taking into consideration your body type and the shape of your fingers.

K18 Classic Oval Ring / 2.6mm

This is a thickness that is generally chosen by women. It is neither too thick nor too thin, giving it a balanced look that is typical of a wedding ring.

K18 Classic Oval Ring / 3.2mm

It has just the right amount of volume without being too bold, and is thick enough to be durable.
This thickness is often chosen by men and is strong enough for long-term use.
It is also chosen by women who like accessories and jewelry and want to wear them in a slightly casual style.

K18 Classic Oval Ring / 3.8mm
K18 Classic Oval Ring / 4.4mm
K18 Classic Oval Ring / 5.0mm

As the ring gets thicker, it has a stronger presence and a more casual impression. As the thickness increases, the mass of the material increases, giving the gold a more substantial feel. It is also strong enough to withstand many years of use. Its durability is less likely to decrease with repairs, making it a thickness that you can enjoy for a long time.

The 3.8mm is casual and recommended for fashion lovers.

As the maker, I chose a thickness of 4.4mm. It feels thick and casual, but I chose it because I thought it would look cool when I become a grandfather.

The 5.0mm ring is quite thick and casual for a wedding ring. It looks very cool when worn on the index finger, so we have included it in our lineup.

There are basically six thicknesses available, but we can also make custom thicknesses upon request.

[About engraving]

Beautiful and delicate engraving can be done using a precision laser.
Each one costs 5,000 yen, and if you order two with the same engraving, the price will be 8,000 yen.

Although there is an additional charge, we can create beautiful engravings with an accuracy of 0.01mm or better using our own equipment.

Since this is not a ring with free engraving (including engraving), you can choose the ultimate simple ring without engraving. About 30% of our customers have chosen not to have engraving.

We will take full responsibility for repairing any ring you purchase.

Although we are a small brand, our workshop is equipped with all the tools and machinery necessary to enable us to produce everything in-house, and we are well-equipped to provide thorough after-sales support after purchase.

We sell our products responsibly so that you can enjoy them for a long time, so please feel free to leave any repairs after purchase to us.

Learn more about alteration prices

- Deep scratches and engravings can be removed and repaired by adding metal using laser welding.
Scratch removal: From 3,000 yen Engraving removal: From 20,000 yen


- To increase the size, simply hammering or stretching the ring will make it thinner, so we cut it apart and add more base metal to repair it neatly.
10,000 yen and up (plus bullion cost)


- One method is to apply pressure using a special size reduction machine to fix the problem, but this will cause the shape to become distorted, so the part will need to be separated and then re-welded.
From 5,000 yen
