Gemstone Posts

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!

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!!

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!!

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!

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.

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.

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!

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

I look forward to meeting new friends!!

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!

After digging through a box the other day, I decided I finally needed to organize my collection of rocks garnered from my many trips to the North Georgia Mountains. I was surprised and excited when I went through my plastic bags and grouped the stones together. I didn’t realize all the cool stones I had!

Hematite:

Let’s start with hematite. If you recall a previous post on hematite, this stone looks like a dark gray lump, but, once tumbled, turns into a beautiful silver color. The cool thing about hematite is that when rubbed against sandpaper, it leaves a red streak (hence the name hematite, which comes from the Greek root word for blood). Hematite is one of my favorite stones!

Quartz:

Quartz is a great stone, too! It comes in many colors and I haven’t found one I didn’t like. In my collection, I have clear, rose, lemon (yellow), smoky, and the cool pencil quartz. I had clear quartz cut into round brilliant cut stones and they are gorgeous!

The stones below are quartz as I found them. I will start with the pencil quartz. It is a misleading name, as some of the crystals are much larger than a pencil!

I think some of these would look great just hanging from a chain, but a couple of them are too big for anything except maybe a paperweight! Below is a picture of one of the large crystals.

Clear and lemon quartz are beautiful stones, too. I think I might send my gem cutter a couple of the lemon quartz to see what he can do with them. I expect they will be gorgeous! Here are some of each.

Aventurine:

Aventurine is another quartz stone and usually has bits of mica or other minerals that give it a shimmering appearance. Here is my collection of aventurine.

Amethysts and Citrines:

Amethysts and citrines are other forms of quartz. I have a nice collection of each and I have some large amethysts. Which are your favorites?

The two large amethysts are shown on the scale below. Using the conversion of 5 carats per gram, the first stone is 630 carats and the second is 575 carats!

Both of these stones are too fractured to cut into gemstones, but I love the deep purple color of them.

The citrines are a golden version of amethyst. I like the lighter color ones, but the darker ones (second picture) are the ones I might send to the gem cutter to see if he can get anything out of them.

Emerald Collection:

I have a large number of emeralds, too. One of my all-time favorite stones, these are rough and ready to tumble. I might have a few that are suitable for gem cutting.

Moonstone Collection:

If you recall from The Gemstone Chronicles Book Two: The Amethyst, Laura used a moonstone to turn her friends and family invisible during a battle. Now, I haven’t tried invisibility with these moonstones, but I like them!

Garnet Collection:

I find lots of garnets. The garnets are a deep red and its hard to show the color in a photo. I did manage to capture one, though. What do you think of them?

Rubies and Sapphires Collection:

Lastly, I wanted to share my collection of rubies and sapphires. Now, I don’t believe any of these are gem quality stones, but I like them anyway. I think when I start cabbing (making cabochons) in the near future, I will do a few of these just to see how they turn out. Stay tuned for them!

I have more, but these are the favorites of my collection. What do you think? Feel free to leave a comment, subscribe to the blog, email me at bill@williamlstuart.com, or connect with me on social media. I can be found on Twitter, Facebook, and Goodreads!

Gemstones again! I haven’t done a gemstone post in a while (partially because I haven’t been gemstone hunting due to other commitments – like marketing The Gemstone Chronicles), but I now have some very cool stones to showcase! Before I get to the final versions of the gemstones, though, I wanted to show you what the stones looked like when I found them.

Emerald:

The first stone is an emerald. I sent this one over to my gem cutter friend because it had a great green color when illuminated by a strong light. And, the natural shape was pretty cool!

I know the picture doesn’t show the green color. It was difficult to capture…

Quartz:

The second stone I want to show you is a quartz crystal. I found this one and it was extremely clear. Now, I believe the stone is beautiful in its natural state. What do you think?

Citrine:

The final stone is a citrine. For those not familiar with citrines, they are the same stone as an amethyst, but with different impurities to give them a yellowish-orange color.

How did the gemstones turn out? I think they are amazing! Here is the finished emerald. While not as green as Lana’s emerald from posts past, or what I envision the Emerald from the Elven Bow in Book Three: The Emerald, it is a great stone!

If you recall from my Rubies and Diamonds post, I asked my gem cutter friend Gene to facet two round brilliant cut quartz stones. They are 1.25 carats each. Here is a picture of them!

To match these, I asked Gene to cut the quartz rough above in a brilliant cut, as well. I think he did a fantastic job! I can see this as a pendant or perhaps a really big ring!

The last stone is the citrine. I have a bunch of citrines, but they are usually so fractured inside that they aren’t really suitable for faceting. The stone above seemed very clear and, as it turned out, it was!

Apologizes again for the pictures as they really don’t show the beauty of the stones, but, as you can see, this Princess Cut weighed in at 1.7 carats and is a great yellow color!

I have to go through the stones I found this past weekend and see if I can find a few more to send to Gene! I also plan to start creating cabochons after the holidays, so stayed as I post progress on them!

What do you think of the finished stones? How do you think they should be mounted? Gold or Silver settings? Pendants or rings? Let me know how you would mount them?

You can connect with me on social media, too, and let me know what your thoughts about the stones are. I can be found on Twitter, Facebook, and Goodreads, or just send me an email to bill@williamlstuart.com!

Happy Holidays!!
