Colors used to represent each of the 7 chakras.
Crown Chakra using Amethyst: Stone of Spirituality
Third Eye used Blue Sodalite: the Communication Stone
The Throat Chakra being about your power, 'your voice' I used glass for the symbolism of 'clarity' in your abilities.
The Heart is Green Aventurine: Stone of Opportunity
I cheated a little on the Solar Plexus. its a yellow glass but not, because the it is actually being represented by the Tigers eye: the Stone of Confidence at the weight end and the yellow glass is just for the visual rainbow up top.
For the Sacral, Carnelian: Stone of Desire
And the Roots are Red Jasper: Stable Grounding Stone
Used as well is Hematite: the Manifesting Stone
Thingymabobs: The Alternative Arms for YOUR Glasses!
