Keys of buying Hekate

I'll admit that as I was making this, I had buying no design in mind. I knew which stones to use and a basic idea of what it would look like.

Red Jasper represents the fiery ether that burns within the heart of a witch.

White Jade represents the starry heavens of the higher self.

Black Onyx represents that which is hidden, the occult itself. It is the shadow realm in which the secrets of the universe are hidden.

At first, I had only one key as the charm, but as I was making it, I was reminded of the triple crossroads.
The three keys represent past, present, and future.

Each key is removable with a lobster claw to use for spell work or to carry around as a charm as part of the necklace without having to wear the necklace itself.

NOTE: Keys shown are examples. Three keys will be selected meditatively.
