Thursday Challenge "Precious Metal"
see fellow Pbase entries here: http://form.pbase.com/viewtopic.php?f=16&t=36884

I had taken pictures of some jewerly that belonged to my grandfathers and my parents along with my lapel pins showing my ratings as dive instructor and private pilot but figured that many entries would be of jewerly, silver and gold so I went with this.

For those that are not SCUBA divers, this is a steel tank that holds 3443 psi of AIR, 80 cf of it.
I consider that precious when I'm down 30 to 100 feet underwater.
