Chalcopyrite, Leland Blue & Rosarita Mandala Pendant in Sterling Silver
The focal stone in this beautiful pendant is called chalcopyrite. It is from the War Eagle Mine in Alaska. It has a lovely burnished bronze metallic sheen. Hand stamped elements have been stamped and hand sawed; then filed and sanded in minutiae. Each element has been meticulously arranged and soldered to a 21 gauge sterling sheet. A small round specimen of rosarita (see below) and a small round Leland blue (see below) specimen were bezel set at the opposite ends of the pendant. Hung from an 18" oxidized sterling silver rolo chain with lobster clasp closure. The entire piece is oxidized with liver of sulphur & tumbled with a special medium for 12 hours to bring a soft matte finish to the metals, and also accentuate the highlights and bring dimension to the piece.
So what is "Leland Blue"? It's not a natural stone at all, it is actually slag – a waste product from the smelting process used in the late 1800s by the Leland Lake Superior Iron Company. For a more detailed explanation, read this article: http://www.lelandmi.com/about/leland-blue-stones.html
What is rosarita stone? "Rosarita is a unique material, which derives its exceptionally rich, red color from the process of gold refining. It is a unique by-product of the 1960s and 1970s gold refining processes. Alaskan beach sand was smelted for its gold content and the slag by-product was Rosarita, which is essentially a gold-infused glass. The base material for Rosarita is silica (which is quartz particles) mixed with gold at high temperatures."
