this is the March 2012 "Spinning Points" compass from Quilting on the Square. I added the ring of green around it, to go with my other purple/green/blue star and compass blocks.

Compass Jellyfish are tinged orange-brown and have 16 dark brown V-shaped lines radiating from the centre which divide the bell into 32 lobes around the edge. They have four long, frilly mouth arms which extend below their 24 tentacles. Compass Jellyfish change their sex from male to female as they mature. They can give a very painful sting.
If you are stung, the best thing to do initially is to rinse the wound in salt water. Rinse with vinegar (if you have some) as the acid will neutralise the toxin in the sting. Urinating on a sting is unlikely to help. Gently scraping the affected area with a credit card or razor will remove any remaining nematocysts (the tiny poisonous sacs released by the jellyfish tentacles).
A compass is a navigational instrument for determining direction relative to the Earth's magnetic poles. It consists of a magnetized pointer (usually marked on the North end) free to align itself with Earth's magnetic field. The compass greatly improved the safety and efficiency of travel, especially ocean travel. A compass can be used to calculate heading, used with a sextant to calculate latitude, and with a marine chronometer to calculate longitude. It thus provides a much improved navigational capability that has only been recently supplanted by modern devices such as the Global Positioning System (GPS). A compass is any magnetically sensitive device capable of indicating the direction of the magnetic north of a planet's magnetosphere. The face of the compass generally highlights the cardinal points of north, south, east and west. Often, compasses are built as a stand alone sealed instrument with a magnetized bar or needle turning freely upon a pivot, or moving in a fluid, thus able to point in a northerly and southerly direction. The compass was invented in ancient China sometime before the 2nd century, and was used for navigation by the 11th century. The dry compass was invented in medieval Europe around 1300. This was supplanted in the early 20th century by the liquid-filled magnetic compass.
Other, more accurate, devices have been invented for determining north that do not depend on the Earth's magnetic field for operation (known in such cases as true north, as opposed to magnetic north). A gyrocompass or astrocompass can be used to find true north, while being unaffected by stray magnetic fields, nearby electrical power circuits or nearby masses of ferrous metals. A recent development is the electronic compass, or fibre optic gyrocompass, which detects the magnetic directions without potentially fallible moving parts. This device frequently appears as an optional subsystem built into GPS receivers. However, magnetic compasses remain popular, especially in remote areas, as they are cheap, durable, and require no electrical power supply.

It is described as "small bows with screw"

Compass Royston YIL1225 seen at Newcastle Central station working the rail replacement service. (16/02/13)
I originally bought this pendant for a gift for my sister-in-law but ended up giving her a different necklace instead. It's taken me a month to figure out what I wanted to do with it, but I finally put it in a 4-in-1 choker with swarovski & glass dagger beads, & a touch of pink links in subtly varied hues. Shame I don't have more pink to wear it with. I may pick up another of these stained glass medallions in black.
