Emerald is one of the big three colored gemstones, alongside sapphire and ruby. Emeralds come in a variety of green tones ranging from yellowish-green to bluish-green, and often have a satiny "glowing" appearance in the light. Tiny inclusions in the stone actually help create this glowing satin effect. The finest emeralds were historically mined in Colombia, but today many high grade stones are also found in Zambia and Brazil, among other places. Emerald is the birthstone for May.

Tanzanite is a relative newcomer on the gemstone scene, but it's also one of the most popular. Introduced in 1968, it was added as a December birthstone in 2002. All the world's tanzanite is mined in one small area of Tanzania. Tanzanite comes in a wide range of colors, but it's the bluish-violet stones you want to look for. Pale lavender tanzanites are very popular, but the finest stones have a predominantly blue color with flashes of violet. Tanzanites will change color slightly as you rotate them and view them from different angles, at times appearing more blue or more purple.
