Agates Found Today

Agates Found Today

Agates are an additional find when looking for sea glass in this area of Washington, USA.

I know that in Oregon and also other places, I'm sure, there are more agates and more variety. We have heard of "Agate Beach" in Oregon, and there are probably many other "agate beaches."

But I wanted to share what you can find in a few hours at beaches in our area as far as agates go. These were found on July 27, 2009.

As a matter of fact, I thought I had found a piece of red sea glass. But as you can see in the photo, it actually was a small red agate!

When we are looking for sea glass on the beaches near here, we pick up a LOT of other stuff, including driftwood, agates, many beach pebbles or rocks (we try to keep them under 2 inches in size), a FEW seashells, etc.

But we ALWAYS find some agates.

If you know anything about agates, we would love to hear from you, as we are uneducated about them.

During my childhood days I have the hobby to collect agates
from seashore. If w wash it and polish these pebbles it will look really beautiful and it can even use to decorate landscape.

by: Angie

My boyfriend and I are agate freaks and just recently started collecting them in the last 4 years.

We have close to 2,000 that we have collected near our home on Camano Island and recently started a collection at a place that we stay on Orcas Island.

The sizes we have collected on Camano Island range from very small to a little larger than a golf ball.

We have inquired with a few different places and have been told that an agate really has no value - but to us; some of the ones we have are priceless.

I have a blue one that is one of my favorites and it is about an inch in diameter.

We are planning a trip to Agate Beach as we have heard that is a great place to hunt.

Puget Sound agates
by: agatefinder

I've enjoyed collecting agates since I was a child walking with my grandfather, my favorites are the very clear ones with color, and the ones that have worn to a smooth almost polished egg ready to be in a pendant.

The other day I picked up a display frame that has glass on both sides, I placed my agate collection in it and put it in the window, It is a great way to display them.

I did a Google on Puget Sound agate geology and found a lot of good information at various universities on the subject.

Agates here are uncommon but not rare, same as down there in Whitbey.

Agates come from vocanic vugs (holes in vocanic rock) located in the sound which slowly wash up after storms or when you get lucky.

WA agates tend NOT to be banded whereas the Montana and Lake Superior tend to have bright banded patterns great for cutting.

BUT always, look closely in your agates.. I polished and mounted one that looks like a eye inside from here nice 1/2" pendant sized:)

Alberta Agates

I have been finding agates in Alberta and Saskatchewan for a few years now but cannot find any information on Western Canadian agates...

Washington Agates
by: Aman

I have been hunting those agate gems here on the East side of Washington for the last 30 years and I still have not found enough. It's an agate addiction I can't shake.We have some excellent alluvial gravel deposits here in SE Wash that have produced some amazing agates. To learn more vist the Treasure Hunting Wiki

Iowa Agate Hunter
by: Anonymous

I guess I don't know what people all know about agates here, but I can share my basic knowledge.

I'm from Iowa, we have some nice agates, and further up into Minnesota there are really nice ones.

Agates are a volcanic rock, I'm pretty sure made of silica oxide. Silica is what makes glass glass and that's why it has the similar transparency.

The nice white bands you see are quartz and many times there's a quartz "eye" in the middle. The eyes are beautiful and prized by buyers.

It's pretty cool to think about magma deep in the earth cooling just right to form these beautiful gems.

I'm moving to Washington in a week! and can't wait to do some hunting. Many times where you find jasper you will find agates too. Peace and love to you all.

Your Agates

I am so far up to about half that amount of exactly those colors, sizes and shapes.

I love the sport of finding them.

My children can spend many hours on the beach looking for glass and have also learned to recognize agates!

Agates and Beach Glass
by: David and Lin

It's surprising to me that we haven't had any other comments on agates. I know there are a lot of beach glass fans in Washington and agates most of the ones we know also pick up the agates.

We don't know much about them except: Old timers have barrels full of them, so they are not rare.

There are rare ones but they are hard to find...that's why they're rare!

Some of the "common" ones though are absolutely gorgeous.

Here's a book that is highly recommended and not expensive: Agates Inside Out

"...for the more commonly seen agates, this is a superb book.

"The author clearly describes the formation, various theories for the banding development, what types of rocks have some of the best agates, how to evaluate the agates based on numerous factors (color, shape, luster, banding, pockets, composition, and more), and where to find agates.

"Of the most prominent types of agates known, she provides excellent descriptions that are complimented by outstanding images of photographer Thomas Shearer."

Did anyone give you sea agate info?? We just moved to Birch Bay and are finding them everywhere. We don't know exactly what they are, how they form, if they have value (other than their lovliness!) Saw you post, was curious if anyone replied. Be well, fellow beach comber!
