Stone is a natural substance, a solid aggregate of one or more minerals or mineraloids. For example, granite, a common rock, is a combination of the minerals quartz, feldspar and biotite. The Earth's outer solid layer, the lithosphere, is made of rock.
The Philosopher's Stone is a legendary alchemical substance capable of turning base metals such as mercury into gold or silver. It was also called the elixir of life, useful for rejuvenation and for achieving immortality. For many centuries, it was the most sought-after goal in alchemy. The philosopher's stone was the central symbol of the mystical terminology of alchemy, symbolizing perfection at its finest, enlightenment, and heavenly bliss. Efforts to discover the philosopher's stone were known as the Magnum Opus ("Great Work"). The symbol for the Philosopher’s Stone is the Squared Circle; illustrating the interplay of the four elements of matter.
Alchemists considered stone to be one of the eleven mundane elements. As such, I made this a multi-cache in my series. Enjoy and Good Hunting!
Bonus! I have created a home-made geocoin prize to cache hunters who find all eleven geocaches representing the eleven mundane elements of alchemy: stone, sulphur, zinc, antimony, phosphorus, magnesium, arsenic, bismuth, boron, platinum, and potassium.
This is a home-made geocoin made from cast resin and hand painted. You can make it a trackable geocoin through the third-party service www.geotrackable.org service (it won't be trackable on geocaching.com). To earn one: 1) Find and sign the logs for all eleven geocaches listed above; 2) Enter the correct coordinates for each in the geochecker +; and 3) Send the geocoin passphrase the Geochecker+ will give you to me via Geocaching.com's message service. I'll verify you have found and logged a find on all five and send a prize geocoin to you.
NOTE: This prize geocoin is optional. All you need to do to log a find is find and sign the log. This is merely a bonus.
