The Mason Celtic is a heavy gauge, Sterling silver, "Mason" shape buckle with our Irish heritage in mind. Negative space has been carved out of the Sterling silver base, and then filled in with hand cut 18k yellow gold overlays for a smooth & flush look. This piece is then finished off with dark antiquing around to give it an old worldly look. Measures approx. 3" x 2" and fits up to a 1.5" belt strap.
