About The Artist :: John Glossa, Gemologist :: Craftsman & Designer

I am a craftsman and designer that creates distinctive jewelry designs in the precious metals of silver and gold; often set with fine gem materials cut from rough or with finished and polished goods.

As you can see from the images above, my finished work spans a variety of styles. Some of my favorite works come to life with the client or recipient in mind. To create a work of art and then have a person express joy in its finished composition is a very much a delight.

A popular theme in my work since 2005 is a stylized Barbed Wire design. I have produced a variety of jewelry items in this "Barbed Wire" motif with warm reception. On my site you will find an entire category dedicated to this style.

Another favorite of mine is the use of rough gems and crystals, which may include partially faceted and polished surfaces, allowing the viewer a "window" into the stone. I find it interesting how light "plays" through the irregular gemstone surfaces in the rough and the contrast of the partial "windowed" surfaces.

One of my inspirations is the comparable way the low winter sun rays can pierce standing ice. In a similar gemstone use, and inspired by mans early technology, some of my work includes “points” (arrowheads) fashioned from a variety of remarkable gem materials.

Yogo Sapphire

By John Glossa December 18, 2021

Montana is know for sapphires of many colors, but a Yogo sapphire is truly “Top Shelf”. The deep blue color of a fine Yogo Sapphire is nearly unrivaled. Many sapphires and other gemstones exhibit “hints” of secondary colors. Meaning you might typically see a blue sapphire with a perhaps a touch of green. It may not be obvious at first glance, but it changes the “pure blue hue”. A fine quality Yogo Sapphire is simply blue. Thus the reason a Yogo Sapphire commands great attention (and price) amongst sapphire enthusiasts and collectors. Only one area in Montana are these gems mined-Yogo Gulch. Near mid-state in Montana, near a town by the name Lewiston. Originally the area was mined for gold in the late 1800’s and the little blue pebbles soon got attention. The story goes on involving some of the most important jewelers on the East Coast and beyond.
