Agate must be polished to bring out its full charm; unpolished specimens are dull and ugly. It usually forms in rounded nodules or knobs which must be sliced open to bring out the internal pattern hidden in the stone.
Literally hundreds of Agate types were coined with special variety names. Most of these are hardly known, and new ones are made up every year.

The name Citrine is derived from the citron fruit, a yellow fruit similar to the lemon.

Tourmaline  -  is the most varicolored of all gemstones. It occurs in all colors. But red, green and multicolored are its most famous gem colors. Scientifically, Tourmaline is not a single mineral, but a group of minerals related in physical and chemical properties.

Turquoise  -  is an opaque, blue to green mineral. It is rare and valuable in finer grades and has been prized as a gem and ornamental stone for thousands of years owing to its unique hue.
