The volcanoes in Costa Rica were the genesis of the Silver + Gold Slice Cuff, the widest cuff in the collection. The bold piece is made of 22k gold and blackened Argentium silver. A trio of black diamonds and a splash of gold dust bring a heightened sense of style to this handsome piece. The Silver + Gold Slice Cuff is also available in a narrow version, at a lower price point.

Our midsize men’s cuff - the Silver Slice Cuff – is made of oxidized silver. The predominantly smooth finish is enhanced with a swash of texture to add interest to this solidly male piece of jewelry.

For the man drawn to chain jewelry, KMJ offers the Heavyweight Black + Gold Chain Necklace in 22k/18k gold and oxidized silver. The 27-inch hand-forged chain is made of solid gold and dusted gold links fused with oxidized Argentium silver. The companion Black + Gold Chain Bracelet is made of the same materials and also hand-forged in our KMJ studio in Denver.

Inspired by the iconic Flatirons in Boulder, Colorado, the Boulder Necklace is a pendant piece made of 22k gold and oxidized silver. The necklace is available in two lengths. Three black diamonds adorn the pendant on the shorter necklace.

No unique men’s jewelry line would be complete without wedding bands. The KMJ collection features four unique wedding bands in 22k/18ky/14kpw gold and oxidized silver. Choose from bands in a satin or matte finish, in gold or oxidized silver with a solitaire black diamond. Masculine, contemporary jewelry for the man with exquisite taste.
