About the Production

Production takes 3 to 6 months. We will proceed at your pace.
Full custom orders start from ¥500,000 (approx.).

Prices vary depending on design, materials, stone type, and size.
During the initial consultation, we will propose feasible options tailored to your budget.


01. Consultation
Online | Approx. 1-2 hours

Please feel free to contact us. We will ask about the occasions you want to wear it and the sentiments you wish to convey. We will carefully listen to your aesthetic preferences, wishes, sentiments, budget, and delivery timeline, and together, we will envision the direction for your unique custom order.



02. Design Deposit Payment
¥55,000 (tax included) | After proposal approval

You will pay a deposit to proceed to the actual design process. Payment can be made via our online store, card withdrawal, or bank transfer. This deposit will be applied to the final total payment.


03. Design Proposal from Designer

After the deposit payment, the designer will conduct another consultation if necessary. Afterwards, Yamakata will propose a unique concept and design just for you. We will explain the design intent directly in an online meeting, and together we will create your ideal piece by making adjustments according to your requests. Please consult us as many times as needed until you are satisfied.


04. 3D CAD Modeling & Quotation

The confirmed design will be precisely rendered into CAD data, allowing you to visualize the finished jewelry. Simultaneously, a formal quotation will be provided, including the cost of stones, precious metals, and processing fees. We will proceed to full production once you are satisfied with the design and price.


05. 3D Model Confirmation

We will create a life-sized resin sample. You can physically examine the size, comfort, and volume that cannot be fully appreciated on screen. For rings, this is a convenient option to try on at hand, imagining it stacked with other rings.


06. Remaining Balance Payment
Final confirmed price | Before main production

Upon payment of the remaining balance based on the quotation, we will commence with the main production.


07. Main Production

To create a one-of-a-kind piece of jewelry, we will handcraft it from your dedicated "prototype." Using that prototype, skilled artisans at our workshop in Yamanashi Prefecture will meticulously handcraft each piece.


08. Completion and Delivery

The completed jewelry will be delivered in a special MON LA VIE jewelry box. May it become a precious piece in your life.
