A very cute 9 carat gold hour glass, made using real glass and perhaps silica, or maybe ground stone.
 
The hourglass is symbolic to time's inevitable passing. The hourglass is a symbol of death, the end of time on Earth, but also a symbol of rebirth and new beginnings when turned over. The winged hourglass is symbolic of man's fleeting time on Earth.
 
You don't get much time with this hourglass - maybe two seconds!
 
Additionally, the two containers of the hourglass are an analogy on their own: that the need to flip the hourglass signifies the cycle between life and death.
(As above, so below)
