In the gemstone world there are a special group of gems known as phenomenal gemstones. These are gems that exhibit special optical phenomena, including asterism (the star effect), chatoyancy (the cat's eye effect).
Since these phenomenal gems are fairly rare, they naturally attract the attention of buyers.
