Gemstones and Fluorescence – Who Knew!?

by Leave a Comment

I learned something new recently (at least new for me). I accidentally discovered, through an unrelated web search, certain gemstones exhibit fluorescence under ultraviolet (UV) light. Now, this may not be news to some of you, but it surprised me!

Fluorescence:

What is fluorescence and why do some gemstones exhibit it and others don’t? According to an article by Hobart M. King, PhD, RPG on Geology.com, certain minerals can absorb a small amount of light and then emit a small amount of light in a different wavelength. This change in wavelength appears as a color change to the human eye. Here is a link to the article so you can see more for yourself!

Additional research taught me fluorite, rubies, some emeralds, and diamonds fluoresce. What do I have from my many rock hounding trips to the North Georgia Mountains? Rubies and emeralds (no diamonds, but I may be headed to Arkansas later this year to see if I can find a diamond or two, but that will be another post)! No fluorite that I know of, though. To test my rocks, I asked for a UV flashlight for Christmas and I was lucky enough to get one.

Checking my rock collection:

After the Christmas festivities were complete (including a delicious prime rib linked here), I spent time examining my rock collection for signs of fluorescent stones. Guess what? I found some! The rubies show up well (chromium, which gives rubies their red color, is an activator for fluorescence) and a few of my better emeralds have a slight reddish glow. Who knew? I wondered why the sapphires didn’t fluoresce and discovered that iron can dampen fluorescence, even though the titanium can acts as an activator. Both of those elements give sapphires their blue color. Here are a few pictures to illustrate the change with the UV light. The first two are rubies under regular light and then under the UV light. I love the pink color!

Gemstones Under fluorescence

The next two pictures are of a yellow rock that I really don’t know what it is, but it glowed a lovely pale green under the UV light.

I realize using a long wave UV flashlight like I received at Christmas will not show the fluorescence on all the stones that possess the property. For that, I’d need a shortwave UV lamp. I may have to order one to see what the difference between the two devices is. If I can get one that is portable, I can take it with me and use it during my rock hounding excursions.

Safety First:

If you decide to use a UV light, make sure to use it safely. UV light is the same light that causes sunburn, so don’t shine the light on your skin. Don’t look into the light directly and don’t shine it on another person or a pet. Wear UV protective glasses, too!

Did you know about gemstones and fluorescence? Leave me a comment and let me know. I’d love to see some of your pictures. As I find more fluorescent stones, I’ll try to post pictures.

New Rock Polishing Toys – What Do You Think?

by Leave a Comment

New Rock Polishing Toys!!

Gemstones fascinate me and are key elements in The Gemstone Chronicles fantasy adventure series I wrote. I’ve been looking for cabochon equipment for a while now and I lucked up upon a vintage Highland Park A-50 and a Rock Rascal Saw. The A-50 is mounted on a rolling cabinet and the saw is firmly installed on a nice little table. Check out the pictures below!

The repairs:

Given the equipment hadn’t operated in a while, I had a bit of work to do on the machine. First thing I did was to replace the power cord to the A-50 motor. Once I finished that little repair, the motor ran perfectly. I discovered the water pump bucket was rusted through, but that didn’t stop me. I cut a 5 gallon plastic bucket down to size and it fit like a glove inside the original bucket. The pump discharge fitting was cracked and the hose wouldn’t fit properly, so I engineered a fix and it works amazingly well!

The Rock Rascal, as you can see from the picture above, needed a new power cord, too. Luckily, I learned a bit about electrical and electronic stuff back in my Navy days, so, like the cord for the A-50, it was an easy fix. Doesn’t make me want to be an electrician again (like I was right after I left the Navy), but it’s satisfying to make it work. Once complete, I op tested it and everything ran smoothly.

I think I might modify the A-50 to add more wheels, but that will be down the road. For now, I’ll pick up various grit belts to use on the expanding drums and use a 6 inch wheel I received for Christmas on the Rock Rascal. Now, I just need a water source and return for the wheel.

The equipment package included a new 6 inch diamond blade for the Rock Rascal, a dopping pot, dopping wax, and cabochon templates. I’m all set now (or will be as soon as the new belts come in)!

What do you think about my new rock polishing toys? Personally, I can’t wait to see if I can make a cab or two. Maybe I can do something with all the rocks I found during my gemstone hunting trips. I might even be able to polish a sapphire or ruby once I get diamond belts for the expanding drums.

Quartz, Topaz, Emerald, and Fairy Crosses!!

Quartz, Topaz, Emerald, and Fairy Crosses!!

I went rock hunting with my brother and niece recently. We found lots of great rocks and I thought I’d share a few of them. First is a nice piece of quartz (I like to call them pencil quartz but this would be a BIG pencil!). The rusty color is internal to the rock, which is pretty cool! I think I’ll try to polish it a bit, but don’t really plan on changing it much. I like the way it looks!

Quartz point

The second find of the day was a great piece of topaz. The topaz we find is usually clear or maybe has just a touch of blue in it. As you may have read in previous gemstone posts, topaz’s blue color can come from heat and exposure to radiation. North Georgia ‘s mountains have a lot of granite (which may contain trace radioactive elements). I think I’ll play around with a smaller piece of topaz and a butane torch to see if I can get color enhancement. If so, maybe I’ll try it on this piece. At 168.4 carats, I don’t want to damage it.

The last find I want to share is this great piece of moonstone (I think). I love the orange colors and I believe it will make a great cabochon. I’ll cut a slab or two off it and see if I can get it to shine. I’ll post pictures and let you know how it works out.

Orange Moonstone rock

In addition to the ones I found, I ordered a bag of chiastolite fairy crosses and staurolite fairy crosses (these came from Fannin County Georgia). If you recall from The Gemstone Chronicles Book One: The Carnelian, the elf Findecano was trapped in a chiastolite fairy cross, so I had to get me at least one. And Aidan found a bunch of staurolite fairy crosses before Maggie found Findecano’s prison. Given how important fairy crosses are to the books, I just had to have some.

Fairy Crosses

The last picture I wanted to share with you is this emerald. I found this one a while back and want to take it to my friend for him to examine and cut for me. This one is about 16 carats, but it has a great green color and I hope he’ll be able to create a beautiful stone from it!

Emerald Rough

I’ll be heading out for another rock hunting excursion soon. If I find some noteworthy specimens, I’ll be sure to post pictures.

Gemstones and Wire-Wrapping – or What I’ve I Been Up To Lately!!!

by Leave a Comment

I’ve been reading, doing a little writing (revisions on The Gemstone Chronicles and a new work-in-progress) and I haven’t done a post about gemstones in quite a while. So, I wanted to share some of what I’ve been up to with my gemstone collection (which keeps growing!). Because I have so many rocks now, I decided to take up wire-wrapping. Before I get to that, though, I wanted to share pictures of a few tumbled stones that I really like. I believe three of the rocks shown below are obsidian, but the fourth one is a smoky quartz. I would love to show you the light shining through it, but the picture just wouldn’t work.

In the picture above, the smoky quartz is in the upper right and looks similar to the other stones. However, when the light shines on it, you can see through the stone.

Those are just a few of the stones from my tumblers (which run 24/7). Having all these tumbled stones led me to try my hand at wire-wrapping as I mentioned above. It’s a lot more difficult than I thought it would be and I watch a lot of videos about different types of wrapping. I try to keep mine fairly simple, since I am still learning. Below are a few examples of my efforts.

The quartz stone below were drilled using my Dremel drill press stand. It did a great job and made a clean smooth hole in the center of the stone. Perfect for wire wrapping! Here is a picture of my setup

I know I have a lot of work to do and much more practice to go before the techniques are learned and the results acceptable, but I’m having fun!

Because I need some thinner pieces (and you can’t count on finding those in a natural state), I’m going to start using my tile saw to slab some of my larger rocks. I’ll do a post on that soon. After cutting the slabs, I’ll use my templates to get rough shapes and then throw the stones in the tumbler to polish them and get them ready to  wire wrap. I won’t make perfect shapes, but that’s fine by me. I prefer a more organic look anyway!

Wire-Wrapping – My First Attempt (Not My Last)!

by Leave a Comment

Readers of my books (The Gemstone Chronicles) and this blog know I love gemstones! I try to go gemstone hunting about once per month, and my two rock tumblers run continuously turning out polished stones by the 3 lbs. barrel full . In fact, I have gotten quite a nice collection of tumbled stones (as evidenced below)!

Wire-Wrapping Tumbled Stones

So, what to do with all these gorgeous stones? I pondered the question for a short time, and then decided I would try my hand at wire-wrapping them. And, since I received a Dremel and a Dremel workstation as gifts, and had a set of diamond drill to use in the tools, I could drill holes in them, too! In addition, my lovely and adorable bride (Lana) gave me the tools from her experiment in beading a few years ago, and I had everything I needed to give wire-wrapping a shot. Here is my drilling station. The plastic container holds water (keeps the rock and drill bit cool) and a piece of rubber (so I don’t drill through the plastic). Pretty cool!

How did my experiment work? Well, I drilled holes in an amethyst and a piece of jasper I had tumbled and decided to give the jasper a try. Below is what the jasper looked liked after drilling.

Wire-wrapping Jasper

Now for the drilled and wrapped piece!

I like the way it turned out and I think it will make a great pendant. I still have to do the amethyst and drill more stones, but I think this will be a great way to use the tumbled stones I keep producing. Who knows? Maybe I’ll open an Etsy store in the future!

That’s my first wire-wrapping effort. I know it isn’t great, but I will keep practicing until I get better. What do you think? Is this a good use for my tumbled stones? Leave me a comment and let me know!

Tektite – Glass Rock or Telepathy Stone? You Decide!

by 6 Comments

In The Gemstone Chronicles Book Two: The Amethyst, Nana and Beebop buy a tektite necklace from an antique dealer. The necklace, as it turns out, has telepathic powers. I won’t tell you more, as it would spoil the story! Nonetheless, I’ll tell you more about tektite!

What is tektite?

Tektite, for lack of a better description, is a glass rock. Similar to obsidian, tektite is mostly silicon. However, tektites are the result of meteorite impacts. Yes, that’s right, tektites are glass rocks formed when meteorites impacted the earth, sent molten particles into the air, and which fell back to earth in the strewnfields. Since tektites formed from the impacts, they have different characteristics compared to obsidian. Additionally, tektites might just have a little bit of cosmic matter in them! How cool is that?

Where can we find tektites? Across the globe, a few locations yield the majority of tektite finds. One of those locations, called strewnfields, is in Georgia! The Georgia tektites are known as Georgiaites and, just like the stone in The Amethyst, are green. Other strewnfields are in Texas, Autraliasia, the Ivory Coast of Africa, and Europe. Tektites from the different strewnfields have different characteristics which I will discuss next.

Tektite varieties:

Georgiaites:

I’ll start with Georgiaites. Found principally in Dodge and Bleckley counties in Middle Georgia, Georgiaites are olive green and generally tear drop shaped. Below is a picture of a Georgiaite (Photo by Sean Murray, courtesy of FallingRocks.com). Beautiful and extremely rare, Georgiaites are 35 million years old!

Georgiaite Tektite

Moldavites:

Moldavites are green, too, though a different shade than Georgiaites. Typically found in Czech Republic in Bohemia (no singing of Bohemian Rhapsody, please), the stones are about 15 million years old. The museum quality pieces are gorgeous and often used in jewelry. Here is an example of a museum quality Moldavite. I particularly like the flaky appearance!

Tektite Moldavite

Australites and Indochinites:

Australites spread across Australia and Southeast Asia. By far the most common variety, Australites are dark, usually black. Found across most of the southern half of Australia, these tektites have a unique disk or bowl shape. NASA (according to Wikipedia) used the shape of these tektites when designing the re-entry modules for the Apollo Space Program!

Tektite Australite

Due to the size of the impact, part of the same strewnfield reaches into Southeast Asia. The tektites found here – called Indochinites – are black like the Australites. Both Australites and Indochinites are much younger than Moldavites or Georgiaites, dating to about 790,000 years old. Here is an Indochinite.

Tektite indochinite

Ivorites:

Lastly, we talk about Ivorite. Found along the Ivory Coast on the Western Cost of Africa, these stones are only about 1.3 million years old. Because of the unstable political climate in the area, I couldn’t find a picture of an Ivorite to include in this post. As a result of the instability, few have been excavated. The found Ivorites resemble Indochinites.

In The Amethyst, the tektite was from the Georgia strewnfield. According to HealingCrystals.com, tektite encourages telepathy and helps with lucid dreaming and astral travel. Sounds a lot like what Nana and Laura experienced, but you’ll have to read the book to find out more!

Obviously, I took some license with the properties of all the gemstones in The Gemstone Chronicles series, but I enjoyed learning about the magical and mystical properties the stones possess. And tektite was a great addition to the collection!

What is your favorite gemstone (or gemstone power) from the series? Aidan’s double-terminated quartz is my favorite. Laura’s invisibility power is the best power, too! What about your favorite? Leave me a comment and let me know! I look forward to it!
