Note this is a high dome well polished stone so you will see a reflection on the side-the stone is solid and the colour uniform.

 

Tourmaline with tiny parallel inclusions sometimes display a strong cat's eye effect when polished. The cat's eye or chatoyancy effect is most easily seen in strong light, especially in sunlight. Tourmaline cat's eye stones are usually found in pink and green. They are not uncommon but can be difficult to find, making them of interest to collectors. Since tourmaline cat's eyes are usually cut as cabochons, one can often find fairly large pieces

 

 

 

 

 

 Tourmaline is a crystal silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Tourmaline gem stones come in a wide variety of colors.Tourmaline has a variety of colors. Usually, iron-rich tourmalines are black to bluish-black to deep brown, while magnesium-rich varieties are brown to yellow, and lithium-rich tourmalines are almost any color: blue, green, red, yellow, pink etc. Rarely, it is colorless. Bi-colored and multicolored crystals are common, reflecting variations of fluid chemistry during crystallisation. Crystals may be green at one end and pink at the other, or green on the outside and pink inside: this type is called watermelon tourmaline. Some forms of tourmaline are dichroic, in that they change color when viewed from different directions.
