WORKSHOP OVERVIEW
In MITUBACI's engagement ring workshop, you will handcraft the ring portion. Choose from our selection of platinum and colored 18k gold; our most popular materials are platinum and our original 18k champagne gold. Select your preferred diamond carat from 0.1ct, 0.2ct, 0.3ct, or 0.5ct and it will be set by our craftsmen on the spot on the ring you have made. Other than 0.1ct diamonds, all diamonds come with a certificate of authenticity.
Like the image above, you may also wish to opt for senban finishes for a more refined and professional look.
MITUBACI 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
MITUBACI engagement rings are made with natural diamonds of the grades used in our custom-made products. 0.1 ct. to 0.3 ct. diamond grades are available in F color or better, SI-1 or better, and triple excellent or better. 0.5 ct. is available to suit your budget. You can choose the grade of diamond that best fits your budget. A certificate of authenticity is also provided as a proof of quality.
Diamonds are measured by international standards called the 4Cs, which are an objective way of evaluating diamonds: Carat, Color, Clarity, and Cut.
A carat is a unit of weight of a diamond; one carat is 0.2 grams. MITUBACI Tokyo offers 0.1ct, 0.2ct, 0.3ct, and 0.5ct diamonds.
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
Similar to other workshop menu at MITUBACI Tokyo, Customers may engrave their names and initials, special dates, or even messages at no additional cost. Customers can choose between hand engraving by yourself with metal stamps for an enhanced handmade vibe (left) and hand engraving with engraving machine done by our artisans for a neater result (right).
