Its so weird cause we went fossicking on the weekend and got some sapphires and topaz but the most powerful gem we found was the spinel's mainly black and green (TINY I should say).
IMHO - and experiece
Clear Spinel rejuvenates mind, body and spirit, promoting new avenues for success.
Green Spinel dissipates emotional discomfort and acts as a conduit to inter-dimensional communication.
Black Spinel invites the work of mages, wizards and prophets into your life.
Violet Spinel enhances the connection with ancient sources of truth, and amplifies inherited wisdom.
Red Spinel enhances camaraderie, enthusiasm, courage, pioneering and survival skills.
