Beautiful things but they're made of tears .

Dad was an opal miner.

And another- Mookaite- this stuff can be heat treated and knapped into beautiful blades and arrowheads- quarried in Australia, shipped to America, where I can buy it for about half what it costs me here! JayInOz

This was in the news a couple of days ago.

The Fire of Australia, discovered by the Bertram family in 1946, is the most valuable piece of rough light opal of its size in the world, weighing approximately 5,000 carats. now on permanent display. The 998g (35.2oz) opal, valued at nearly A$900,000 (£550,000; $680,000), is now on display in Adelaide's South Australian Museum.

Some nice opal deposits have been found in Wyoming—

An old friend, Dave Love, had some beaut opals in his drawer at the USGS office in Laramie. Also some marvelous jade— he gave us some apple-green stone for an inlay in our wedding rings.

I have some pieces of petrified wood, found locally, in which all the cracks and veins are filled with blue opal. A friend of mine had several large petrified tree stumps on top of a densely timbered mountain on his farm near the small village of Wollar (now a ghost town thanks to Peabody coal) , the biggest of which he said weighed several hundred pounds and also contained opal. We finally agreed on a day to climb up and have a look at them- when we got to the top we discovered that the largest- probably close to half a ton- had been stolen- dug out of the ground and rolled out- no vehicle access within several hundred yards, steep sides, thick timber. When they finally got it to a road they still had to load it- truly determined thieves :) JayInOz
