Chalcedony Gemstone Jewelry
Chalcedony gemstones set into jewelry such as rings and pendants are very popular gemstones. Their are several reasons. The main one of course is the beauty of the gems and how well they go with gold and silver. Another reason is cost, chalcedony is a relatively inexpensive gemstone, and larger sized gems can be purchased for much less than other comparable sized gemstones. 

Natural vs. Treated Chalcedony
Any buyer of chalcedony gemstones must be aware of the fact that many chalcedony gemstones on the market are treated in color. These treated chalcedony gems owe their color to a dying process that impregnates the gems with a dye to make the stone appear blue or lavender or other color. AfricaGems only sells completely natural chalcedony gemstones.
