Fulgurite

Gemstones

I love a good rain storm, and if you look at the weather reports for this region you already know how badly we need one.  I’m not talking about the gentle little pitter-patter rain or the drizzle for day’s type either. I mean a good ol’ booming desert storm that rolls in during the afternoon, dumps copious amounts of water for 20-30 minutes while making all the noise it can,  and then just as quickly dissipates leaving everything greener and smelling fresh and new.

I love watching the lightning flash across the sky, hearing the thunder roll and echo as it bounces off the mountains and seeing the rivers of water in the road as the earth soaks up the much-needed moisture.

What is Fulgurite:

I think what gives these storms their impressive noise and power is the lightning that builds and discharges,  creating an amazing show of Mother Nature’s might. When lightning strikes the ground, however, it can cause both destruction and also create something amazing as it becomes frozen in the ground as Fulgurite, which is Latin for thunderbolt.

Lightning strikes at a temperature of around 3270 degrees Fahrenheit creating enough heat to instantly transform high silica and quartz soil to glass around the immediate area of the strike.  These tubes are smooth on the inside and are surrounded by partially melted and fused soil on the outside.  Though not very attractive in an aesthetic definition, they are beautiful nonetheless.

A single Fulgurite

Why is it so unique?

So, is a Fulgurite created every time lightning strikes the ground?  The answer would be,  probably not.  Researchers from the University of Florida Department of Electrical and Computer engineering have been studying the effects of lightning on power lines above and  below the ground at their research facility at Camp Blanding near Starke Florida since 1994. Their findings have been that lighting will blow sand up, it will “eat” the soil, and will sometimes form a Fulgurite.  They have found that the higher the silica and quartz content of soil and the more densely it is packed, the more likely it is to create a Fulgurite.

Researchers have also found that lightning will strike the ground and then travel to the water table, sometimes branching out under ground for a few feet before it stops.  In 1996, they found a very large Fulgurite that has set a world record for its size.

Florida boasts the greatest number of Fulgurite since that state also has some of the highest number of lightning strikes with 10-15 strikes per square kilometer each year.  Fulgurites have also been found on the tops of some of the worlds higher mountains like the Alps, Sierra Nevada’s, Cascades, Wasatch and Uinta mountain ranges.

Fulgurites created in nature can range anywhere from a couple of inches to several feet with a thickness from that of a drinking straw to several inches in diameter.  You can even create Fulgurite in a lab setting by passing (arcing) electricity through high-silica sand, but these are small, only an inch or two in length.

Wrapping it up.

Now, before you go out in a thunderstorm looking for lightning to strike the ground so you can dig up your own piece of it, remember that not every strike creates a fulgurite and not every soil is ideal for its creation.  Lightning also travels at about 140,000 miles per hour and can reach temperatures rivaling that of the surface of the sun.  It can also send you back in time…so be careful.

As for me?  I’m going to sit back in my air-conditioned home and hope those clouds on the horizon are here to give us some rain, some thunder and maybe a few Fulgurite.

Zultanite

Gemstones

We’ve all heard, or told, the silly jokes that come inside bubble-gum wrappers – here are a couple to start your day off with a giggle: “What’s black and white and read all over?”  Answer: The newspaper.   “What has four wheels and flies?” Answer: A garbage truck.  And best of all; “What is green, pink and yellow all at the same time?” That may be a new one to you, but the answer is Zultanite!

What is Zultanite:

Zultanite is an aluminum oxide hydroxide AIO(OH) mineral from the diaspore group. These minerals form as metamorphic sedimentary ores in bauxite, the mineral mined for aluminum. Though diaspore was first found in the 1800’s, it’s never been commercially mined until recently, with the material coming from a single mine in Turkey.  It is currently the only source of Zultanite in the world

Why is it so unique?

What makes Zultanite so unique in the gem world are the color-changing properties it possesses.  While most gems have fire to them and will flash different colors, Zultanite is one of the few that changes color depending on the light.  In sunlight, Zultanite is a kiwi green with flashes of yellow and blue.  Indoors, a Zultanite will change to a more olive or even peridot green with flashes of pink and gold.  Under candlelight, a Zultanite will take on a deeper pink tone with flashes of brown, olive green and raspberry.

Zultanite also has the unique property of having chatoyancy, or cat’s eye effect, when it’s cut en cabochon, which makes the color changing properties even more spectacular.  The stones are cut from eye-clean crystals and are never enhanced.  This makes Zultanite one of the most beautiful and natural stones on the market today.

Why is it rare?

In addition to being one of the more beautiful stones on the market, Zultanite is also one of the more rare stones.  Only 50% of the crystals found in the mine are suitable for taking a facet and of those, only a fraction are deemed quality enough to become a gem.  The reason for this is the crystal structure of the stone.  Zultanite is formed as orthorombic crystals with a definite cleavage to the stone.  The lapidary yield from Zultanite is only 2% meaning that 98% of the crystal is waste material due to the orientation of the micro-crystals, abnormally large number of inclusions, and the tendency to break apart during cutting (to give some perspective on yield, most gems have a 30 – 50% yield).

Zultanite Mining:

Mining Zultanite can be a bit of a chore too since the mine in Turkey is located in the Anatolian Mountains and sits nearly 4,000 feet above sea level.  The miners live onsite and work with air hammers with only the light from their headlamps to chisel the crystals from the rock.  The Zultanite crystals are located in soft layers between harder bauxite and must be dug from the rock after they have been located.  Zultanite has a hardness of 7 on the Mohs scale and a refractory index of 1.7 – 1.8.

The owner of the mine named Zultanite after the 36 Sultans of the Ottoman Empire and only the stones coming from the Millenyum Mine can be called by the trade-name Zultanite.  Other diaspores in the region do have color change properties, but none like those from the Millenyum Mine. This mine also has the unique distinction of being a “green” mine.  The miners plant 10 trees for every one they use within the mine and the miners are also fully insured and paid above average wages for the region.

Zultanite

The Millenyum Mining Company also provides materials and maintenance for the village schools nearby.  On a side note; the mine owners have also encouraged people interested in purchasing Zultanite to only purchase from reputable dealers and not to purchase the stone in Turkey, its mother country!  The reason they don’t encourage purchases is due to the unethical practice of some vendors selling color changing glass at highly inflated prices to tourists looking for souvenirs within Turkey.

Zultanite Beauty:

Zultanite has really made an impact in the gem world with its color change properties, scarcity and beauty.  Since the stone is only found in one small area of the globe, Zultanite joins the ranks of other gems, like Tanzanite and Larimar, with the unique distinction of being beautiful and very rare.

Gem Profile July 26: Large Hole Round Beads

Large Hole Round Beads with Leather Cords

Shop Large Hole Beads

My daughter is in charge of the activities for girl’s camp next week and she came to me asking if she could use some of my extra beads and cord to make name bracelets with all of the girls that are attending.  We started sorting through my beads, leather and silk cording and were a little disappointed to find that there were very few beads that fit on the cord I had.  The holes were just too small.

My discovery:

The next morning, I was walking through the warehouse and was thrilled to see Megan unpacking some new beads that were already strung on leather cords.  I just had to have a strand, so I liberated one to take to my desk for a few minutes. I excitedly called my daughter to let her know that I had the answer to our cord and bead dilemma.

Strands of Large Round Hole beads

What I discovered:

These beads are beautiful!  They are the same stones that we already carry, but they are large hole beads that are pre-strung on a nice leather cord.  You can almost use the cord as is, attach a button for a fastener, and have a really cute modern bracelet!

So with this discovery, my daughter is using them for name bracelets at camp. Each girl picks a bead that corresponds to each letter in her name and strings it on the leather or silk cord.  They’re teaching the girls how to make a sliding knot for one of the camp advancements, so this fits really well with learning a skill, and making something meaningful and memorable from camp this year.

More fun projects:

As I was looking at the beads I had at my desk, I realized that they will not only fit the thicker cords, but also larger gauge wire and will look great on the new expandable bangles that are all the rage right now.  I’ve even seen people layer the expandable bracelets alongside the leather bracelets with charms and stones for a great bohemian look.  My son even asked the other day if I could make him a tiger-eye bracelet on a leather cord.

Jewelry Measurement Conversions and Charts

Resource Center

This week were going to focus on a very rare and beautiful gemstone called Zultanite, however Layna, our Gem Profile contributor, was out ill. Since we don’t want to miss the wonderful information that she has to share, we are going to postpone that topic and come back to it in a couple of weeks! I can’t wait to hear what she’s discovered about it and we wish her a speedy recovery!

So, in the place of Zultanite, we are going to discuss the conversions of measurement for gemstones, beads, wire gauge and jump rings.

In the jewelry world, millimeters, as we all know, is a common form of measurement. However, if you’re like me, you have to think about the conversion. Today, I thought we’d take a quick look at how to figure it all out.

If you haven’t been to our Resource Center lately, there is a great article which covers a lot of this information as well. Today though,  I”m only going to touch on a small portion because I want you to all go on a little treasure hunt and see what you can find!

 

How to start:

Cabochons and beads are commonly measured in millimeters (mm), while many people in the United States are more familiar with inches (in). Here are some easy ways to figure out what size cabochon or bead to work with!.

  • To convert inches to mm, multiply inches by 25.4
  • To convert mm to inches, divide millimeters by 25.4

Cabochons

In most cabochon measurements, the height comes first, then the width (which may seem backwards).

Here are some common cabochon sizes, in millimeters and inches.

8 x 6mm Cab

8 x 6mm Cab

0.3″ x 0.25″ Cab

14 x 10mm Cab

14 x 10mm

0.6″ x 0.4″

18 x 13mm Cab

18 x 13mm

0.7″ x 0.5″

25 x 18mm Cab

25 x 18mm

1″ x 0.7″

30 x 22mm Cab

30 x 22mm

1.2″ x 0.7″

40 x 30mm Cab

40 x 30mm

1.6″ x 1.2″

  • Remember, there are 10 millimeters in 1 centimeter, so a 40 x 30mm cab can also be measured as 4 x 3 centimeters. Most rulers in the U.S. have one side for inches, and one side for centimeters.
  • For comparison, a U.S. Quarter is 24.26mm in diameter (across); a quarter is nearly the same size as a 25mm round cabochon.

Cabochon

A U.S. Penny is 19mm in diameter, or 3/4″ across. Here’s a penny compared to an 18 x 13mm cab:

Penny

Beads

Do you want to know the number of beads in a strand? If you know the length of the strand and the size of the beads, you can estimate the number of beads in any strand. Note: this method may not work on beads of different sizes on the same strand.

  1. Take the strand measurement and convert it to millimeters. On Wire-Sculpture, most of our strands are 16″ long, or 406.4mm
  2. Divide the strand measurement by the size of the bead.  For example, we have a 6mm round bead.6mm Bead406.4 ÷ 6 = 67.7

There are about 67 beads in a strand of 16″ 6mm beads. Each strand may vary slightly by a few beads in either direction.

What did you learn?

If you’d like to read more about Wire Gauges and Jump Rings – you can continue reading this article in our Resource Center! It’s great information for anyone from the beginner to the advanced wire artist.

Next week, we have some very exciting news – do you love new beads? I do! We will be hearing all about a NEW line of Large Hole Round Beads that are now available on Wire-Sculpture. You won’t want to miss next weeks profile!
