About Us

Inspired by the judicial pledge, bound by oath promises earnest expression of personal style—through timeless aesthetics.

Chawapat and Rattanarawin Soisiri, both no strangers to the jewellery industry, established bound by oath back in 2020. With a simple and straightforward initiative, Phukao wanted to create jewellery for himself to enjoy. Having been immersed in the world of classic menswear, the founder translates the slick sartorial charm into 18k jewellery pieces that can be worn effortlessly by both men and women.

As a brand catered specifically to gentlemen, bound by oath values quality and heritage, surpassing ephemeral fads. The principle is very well rooted within the fine pedigree of craftspeople themselves. The founding couple own a studio focusing on diamonds and bridal jewellery and in making this label for men—which, of course, can also be very much enjoyed by the ladies—the very same meticulous attention and savoir-faire is put into the creation. As simple as the designs may seem, the superiority is all in the details.

bound by oath brings the imppeckable craftsmanship of high jewellery to each and every one of its creations. The bracelets handcrafted from precious yellow gold are appropriate in every occasion while Signet Rings make a more personal statement. Adhering to the age-old tradition.
