Barse makes jewelry with metals such as bronze, copper, marcasite and vermeil. Among the jewelry on offer as of 2015 are bracelets and rings made of vermeil and a multi-metal tribal necklace. This necklace has tags of copper, bronze and sterling silver hanging from an adjustable bronze chain. A pair of dangle earrings features orange sponge coral descending from marcasite and sterling silver.
Bronze is an alloy, which means it is made out of at least two metals. In the case of bronze, the metals are copper and usually (but not always) tin. Copper is an elemental metal that has been used by humans since ancient times. Besides its beautiful orange color, copper is prized for jewelry because of the ease of stretching, molding and shaping it.
Marcasite jewelry is actually made from pyrite, or fool's gold, but not marcasite. Real marcasite is more brittle than the marcasite used for jewelry. Often, shiny bits of marcasite are embedded into silver. Because it glitters, marcasite jewelry is as popular substitute for much more expensive metals and gems.
Vermeil is made by coating sterling silver with a thin layer of gold. The gold weighs at least 10 karats, and the layer must be at least 2.5 microns thick. No other base metal should come between the sterling silver and the gold coating.
