Senban finishes are created through precision machining using a lathe, resulting in clean, refined patterns. During the workshop, participants will engage in essential jewelry-making processes such as engraving and shaping the ring. Final finishing is meticulously handled by our experienced artisans, ensuring a level of quality comparable to that of a fully custom-made ring. This option is ideal for those who wish to create their own jewelry while achieving an exceptional, flawless finish. (Please note: Senban designs are available only for rings with plain surfaces and widths under 3.5mm.)
