Cryolite is a rare mineral identified with an originally large deposit at Ivigtût in Greenland, but was depleted by 1987. Cryolite can occur as colorless, glassy, white/red to grey/black prismatic monoclinic crystals and has a Mohs hardness of 2.5 to 3. Cryolite has a very low refractive index of 1.34 , which is similar to water; if Cryolite is immersed in water than it becomes essentially invisible.
Siderite is a member of the Calcite group and was originally named in 1845! It sits at a 3.5-4.5 on the Mohs Scale of Hardness and has a trigonal crystal structure. Siderite often has a brown coloration.
These pieces are quite bright, and even translucent in some spots, making it possible to see what is encased beneath. There are many interesting formations throughout, making them ideal for display for many angles.
Cryolite is believed to stimulate the Crown and Base Chakras, balancing the energy flow between them. An interesting aspect of Cryolite is that it is also thought to aid in public speaking by calming nerves before a performance.
Siderite is thought to help with the development of positive thoughts and constructive ideas.
