Ruby

Complex cluster of pink corundum crystals fully crystallized on all sides (with only small point of attachment).

There is mica embedded on the front side, and the back side is where it was attached to massive Corundum.Rubies found at Sivec Mountain, have been mined for thousands of years. It is a marble mine in the Republic of Macedonia. These aren't on the market regularly, and when they are good with a dramatic color contrast from red to white, they are excellent examples of rubies in matrix. They are highly fluorescent, as shown in the third pic. The color is a richer red under incandescent light, vs. the daylight fluorescent pictured.
