Abby and Gail's Anathamite Jewelry

Abby and Gail's jewelry are pieces made with a special gemstone called Anathamite,  Anathamite originates from hell and has been used for centuries to store demonic power.

This demonic power is absorbed from the blood on demons spilt on the gems, causing them to go from a dark murky blackish grey to a bright scarlet with yellow and orange flecks. 

Abby and Gail use these gems in order to keep themselves alive for as long as possible, without them the sisters will start to die due to their cranial malformations (because their heads and faces are fused together) 

These are their favorite pieces of jewelry, Abby's favorites being the necklace and earrings while Gail prefers the ring and bracelet.
