I have been told a couple of different things, 1) it is opalized pitch from a petrified tree, not worth much. 2) It is petrified pitch, from a petrified tree. I have found a nice piece of petrified wood with several pockets of what I think used to be pitch, when I sliced it thin, I was able to see the rings in the pitch. It is very clear and amber in color. Can anyone help?
Amber is fossilized resin. It is not opalized, opal is a silicate, and amber is only resin, no silica. What you have probably found in the petrified wood is carnelian. Carnelian is frequently found in petrified wood in western Washington. especially in the Toutle/Mount Saint Helens area.

It is pretty common to find clear to brown colored pockets in wood. I've read it is caused by green (living wood) that shrinks as it dries while buried leaving voids. The agate or carnelian fills those voids. The dried wood fossilizes one cell at a time (mineral replacement) preserving growth rings, etc. Occasionally you see crystals in pockets that didn't fill.

Tammy, an easy test for amber is to heat a sewing needle to red hot on the tip. Press the hot tip into the suspected amber. If you have amber, it will give off a little bit of smoke which has a pine smell. Real amber is soft enough to be carved with sharp tools, and sanded by hand to a finished shape and polish. Don

rockpickerforever: Supposed to get cold and windy here, couple inches of rain forecast for the weekend, and then some. Even the desert is supposed to get liquid sunshine. We need it, but why can't it rain during the week? So much the for the rock field trip this weekend.

rockpickerforever: Fossilman, making a nice hot batch of the Jalapeno jelly today, yum!! Can't get enough of that stuff! Might go out and use the stove in the trailer, so I'm not breathing chile pepper fumes all day, lol.

rockpickerforever: Oh, I should mention... Cold here is maybe down into the 40s. Not that below freezing or below 0 type of insanity. Who can live in such a place that has those temps? And all that white stuff, uggghhhh!

drocknut: Chili pepper fumes, one way to clear out the sinuses..lol. I can handle the cold (btw 40 doesn't count as cold yet) but that hot stuff you call jelly geez how can you eat that...lol.

rockpickerforever: Diane, it's not the sinuses, the fumes make you gag and your throat burn. Trying to be considerate of poor, sick Lucy. Diane, you just don't know what you're missin. And yes, considering what it costs to live here, 40 degrees IS damn cold, lol.
