HANDMADE ENGAGEMENT RING PROCESSES
Time required: 3 to 4 hours
You may take your rings home on the very same day!
Our artisans who have profound experience in made-to-order jewelry will guide you through the entire workshop on a one-to-one session for individuals and one-to-two session for pairs. From the metal selection to hand engraving, shaping and soldering, applying texture, and diamond setting, the whole process takes around 3-4 hours. The base price of this workshop starts from a standard 0.1 carat diamond, and the best part is being able to create your one-of-a-kind jewelry in the world, complete it and wear it on the very same day!
Choosing Materials, Widths, and Design
We will walk you through our samples and guide you in choosing your preferred material, ring width, designs, and finishes for your rings.
You can also see and confirm the size and color of the actual diamonds and colored gemstones from our extensive stock.
Engraving
You may opt for free engraving methods like metal stamping! Our metal stamp engraving comprises alphabets, numerals, and original icons. Before working on the actual engraving, we will provide you with a silver bar to practise.
If you prefer a more flexible design, such as an illustration or Chinese characters, you can choose the optional laser engraving.
Shaping
The precious metal plate is made into a ring shape. Since this work requires a lot of strength, a wooden mallet is also used to round it.
Soldering
Once the ring is rounded, excluding Platinum, you will solder your ring under the guidance of our craftsman.
* If you choose Platinum 950, the work will be performed by a craftsman in principle, as it requires the qualification of a gas welding technician.
Sanding & Polishing
At this stage, you will work with several tools to smoothen and polish the surfaces of your ring.Here the ring shines so beautifully that it reflects the surrounding scenery.
Also, lathing and milling can reproduce the superb quality of a custom-made engagement ring, despite the fact that it is handmade.
Stone Setting
Our craftsman welds the base to the ring and clasps the stone.
Because of the high level of skill required, the work usually needs to be done by a specialized company, but MITUBACI TOKYO, where real metal engravers are always on hand, can carry out the work on the same day and deliver the final product to you.
Put it in a case and you are done!
Your one-of-a-kind engagement ring is now complete.

WORKSHOP OVERVIEW
In MITUBACI TOKYO's engagement ring making class, you will handcraft the ring portion of the ring. You can choose either platinum or colored gold as the material; MITUBACI TOKYO's most popular material is platinum, while the popular colored gold is our original champagne gold. A diamond will be set by our craftsmen on the spot on the ring you have made.
Like the image above, you may also wish to opt for senban finishes for a more refined and professional look.
MITUBACI TOKYO engagement rings can also be completed on the same day. This is great for those who require the ring urgently. The ring contour is simple and straight, making it perfect to stack with your wedding rings. It is also possible to make your wedding bands concurrently with your engagement ring.
PREMIUM QUALITY DIAMONDS
The ring is made of natural diamonds of the same grade used in our custom-made products. 0.1 ct. to 0.3 ct. diamonds are available in F color or better, SI-1 or better, and triple excellent or better. 0.5 ct. and larger diamonds are available in a variety of grades to suit your budget. You can choose the grade according to your budget. A certificate of authenticity is also available as a proof of quality.
There is an international standard for diamonds called the 4Cs, which is an objective way to evaluate diamonds. 4C stands for Carat, Color, Clarity, and Cut.
A carat is a unit of weight of a diamond; one carat is 0.2 grams.
Diamonds are classified between D (colorless) and Z (light yellow); MITUBACI Tokyo offers diamonds with F color or higher, which is classified as "colorless".
Clarity is an evaluation of a diamond's transparency. It is broadly divided into six categories. In descending order of evaluation, they are FL, IF, VVS, VS, SI, and I. They are further divided within each category, comprising a total of 11 grades.
The GIA Diamond Clarity Scale has six categories, some of which are subdivided, totaling to 11 grades.
MITUBACI Tokyo offers diamonds that are SI-1 (inclusions can be seen under 10x magnification) or higher.
Cut is an evaluation of a diamond's balance, symmetry, and polish. While color and clarity are the innate properties of a diamond, cut is an evaluation of the workmanship. The cut is divided into five grades: Excellent, the highest grade available at MITUBACI Tokyo, and Triple Excellent, the highest grade for overall evaluation, symmetry, and polish.
- Diamonds of 0.2 ct. or more come with a certificate of authenticity booklet from the CGI. While diamonds of 0.1 ct. do not come with a certificate of authenticity booklet, a simple certificate of authenticity is available upon request.
- While workshop participants can complete most of the ring-making process by themselves, our artisans will take over the stone setting process as it is more complicated.
- All diamonds provided by MITUBACI Tokyo are natural diamonds.
MATERIALS
Choose your ring from five colors and metal types. Whatever your choice, there is no additional charge!
Design and surface finish
Snowflake texture is recommended for engagement rings. This texture works well with both platinum and gold, and together with the sparkle of diamonds, they emphasize the overall brilliance of the engagement ring.
Plain
The mirrored finish is a timeless classic. It 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
With reflections like shimmering water surfaces, this is the most popular texture. 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.
Foresta
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
A texture resembling a snow flurry. This texture is best matched with platinum but also looks glamorous in gold. Choose to polish your ring for an emphasized look or mattify for a gentle glow.
Frost
This texture resembles frost on the window in winter. Achieved using a specially made hammer, every ring with the frost texture is one-of-a-kind as the pattern forms differently in the hands of different people. Keep the surface polished to enhance the texture, and mattify it for a subtle finish.
Stella
Stella means star in Italian, and as its name suggests, this texture resembles the captivating raining stars. Combine it with stones of your choice for an even more personalized look.
ENGRAVING
Just like other workshop menu at MITUBACI TOKYO, customers may engrave their names and initials, special dates, or even messages at no additional cost. You can choose between hand engraving by yourself with metal stamps for an enhanced handmade vibe and hand engraving with engraving machine done by our artisans for a neater result.
Alternatively, you may opt for laser engraving to include Japanese, Chinese, emojis, or handwritten characters on your jewelry (additional charges will incur).
