GeneralSweet Home, Linn Co., Oregon USA, Holley Blue Agate

Since I have been at Sweet Home lately and have added some minerals to the Green Peter Dam locality, I have added this to the Sweet Home locality.

Chalcedony, occurring also as Agate at this location often was an intense blue. I do not know the agent responsible for the color.

To the best of my knowledge, the occurrence is closed to collecting.
The recent trips to the area jogged my memory and I found about 400 grams that I had squirreled away.

Here is the rest of the lot that I found squirreled away. There are some pretty nice examples of the occurrence represented here.

Steve that's some intense color in your polished piece! I've found that among American agates, Holly Blue seems to command the most interest and highest prices because their vibrant color even appeals to folks who don't normally collect lapidary pieces. I have some friends in Oregon and they said that the land that this deposit is on was bought by a timber company, and the company absolutely forbids collecting or trespassing these days. I was told the reason why the company cracked down was because a trespasser got accidentally killed by a cable wire while riding an ATV through one of the logging areas and the company doesn't want to be found liable for any injuries or deaths.

Aaron,
Yes, I am aware that agate is chalcedony.
The distinction was made for the purists that insist chalcedony be banded in order to be termed agate.

Some chalcedony from the Holley Oregon site contains banding and some does not. Hence, the reason for the distinction.

And, I believe, quartz is the family with chalcedony, agate and jasper being the varietals.
Not the other way around.

Steve
