St Patrick’s Day Agates

Wow!  We got some pretty ones out of this batch of agates gathered from Tillicum Beach over the last year.

Even as busy workampers, we made time to steal away to recharge our batteries.

We've even got some Newport Blue Agates!

Agates are a variety of chalcedony (if you care).

But if I talk about agate hunting, I really mean pretty-rock hunting.

 If you can see light through it, it’s some sort of agate.  If you can’t see light through it, might be jasper or petrified wood or obsidian?

There are probably a couple other choices on the Oregon coast too.

You (or someone) can actually dye agates; which I find really hard to grasp since they are so hard.

They are basically quartz.  The next one looks like a small geode that was completely filled instead of leaving crystals in a hole.

I like the ones with designs in them.  Sometimes you can’t see the designs unless you hold them up to the sun; or a flashlight works.

Not Sure what this is

The tan part polished to a high sheen.  The white and black parts are more dull.  But it is an interesting piece.

I need a new zipper-pull.  I think I need the one on the lower left to match my jacket.  I’m guessing it’s a green jasper? (for St Patty’s Day)

The photo inserts are flashlight displays of agates on the upper left and lower right respectively.

I thought these demonstrated the most dramatic visual change when backlit.

Blue agates are the big mystery here on the central Oregon coast.  When I first heard about them, they were called Newport Blues.  That’s because they “could only be found in Newport”.  The agate on the lower right looks blue to me, until you put it up to the light.  So, I’m not sure if a purist would deem it worthy of the title?

But I don’t do this for the experts.

Happy St Patrick’s Day!

  1. Beauties! I’m jealous!

    Actually, you can also see through quartzite… I’ve heard it called “sugar agate” because of the granular look of the surface when it’s dry. But when it’s wet, it can just about fool you into thinking it’s an agate. I was down in Bandon this weekend, and there were loads of those little quartzite pebbles glowing up at me from the sand. I heard someone call them “Bandon agates.” The waves tumble them to beautiful round shapes.
