One of three beautiful towers are a rare mixture of moss agate and amethyst that I have only seen a couple times on the market. All towers have the purple amethyst stone somewhere on them with various shades of moss from traditional green to blue. 

if you would like more information, feel free to message me!

Amethyst is a variety of quartz that is purple in color. The purple comes from iron impurities within the quartz and can range from deep purple to lilac to a reddish purple.

Amethyst is commonly mined in Brazil and Uruguay, but can be found on all continents. 

Moss Amethyst is a combination of purple amethyst mixed with moss agate. The moss agate creates thin vein looking threads and branches within the stone.
