This 18-gauge "Agate" mokume gane sheet is made with layers of Argentium® Silver and copper, formed to present an intricate, one sided pattern. The material used to manufacture this mokume gane contains 52.5% Argentium Silver and 47.5% copper by weight/mass. The billet (unpatterned plate) is made with 21 alternating layers of these metals, finished with a thick Argentium® backing that represents about 1/4 of the overall sheet thickness. The metal content percentages may vary somewhat in the patterned sheet (and in each finished item you create) due to the swirling mokume gane effect.

For a striking, high-contrast effect, try exposing some copper on the outer surfaces of a jewelry piece and applying a patina such as Baldwin’s Patina to the piece. The patina will stain the copper dark but will not affect the bright white silver. The result is a wood-grain look with stark, elegant contrasts among light and dark striations.

​​​​​​18-gauge sheet is useful for pendants, mid- and narrow-width ring shanks and for cuff bracelets. As you know, metal sheet has as many uses as there are jewelers and designers who use it to achieve their vision; these suggested uses simply represent some of the more common applications of this metal weight.

This sheet is stocked in 3" x 12" pieces; due to the cutting capabilities of the shear, minimum purchase is 1" x 1/2".

Created by Phil Baldwin of Shining Wave Metals, this mokume gane combines the high quality of Shining Wave products with the brilliant, tarnish-resistant qualities of Argentium® Silver. Because copper can react with skin chemistry, turning skin green, a substantial base layer of Argentium is built into each sheet to help prevent this reaction. Keep this in mind when creating bracelets, rings and other pieces that may have prolonged contact with skin.
