October Birthstone: If you're born in October, Happy birthday.




October is another month with two birthstone choices – Tourmaline and Opal.


TOURMALINE

Tourmaline has become a favorite gemstone among jewelry designer, and gem collectors the world over. Since it is available in a wide variety of colors, it is ideally suited to almost anyone's taste. Tourmaline also is known for displaying several colors in the same gemstone.  These bi-color or tri-colorgems are formed in many combinations; gemstones with clear color distinctions are highly prized.  One multi-color variety is known as watermelon tourmaline, and features green, pink, and white colors bands; to resemble its namesake, the gemstone is cut into thin slices having a pink center, white ring, and green edge.  Tourmaline is found in many localities including Brazil, Afghanistan, East Africa, and the USA.

OPAL

The name opal derives from the Greek Opallos, meaning "to see a change (of color)."  Opals range in color from milky white to black with flashes of yellow, orange, green, red, and blue. An opal's beauty is the product of contrast between its color play and its background.  Opal is a formation of non-crystalline silica gel that seeped into crevices in the sedimentary strata. Through time and nature's heating and molding processes, the gel hardened into the form of opals. The opal is composed of particles closely packed in spherical arrangements. When packed together in a regular pattern, a three-dimensional array of spaces are created that give opal its radiance.

Top 7 Places to Go Gem Hunting On Your Next Family Vacation


Got a rock hound in the family? Consider taking a vacation to one of these geologically rich destinations and you might just find enough gemstones or precious metals to pay for the trip, because you can keep everything you find. You're guaranteed to have a good time looking—even if you come up empty.

Crater of Diamonds State Park

What: Gem quality diamonds
Where: Murfreesboro, Arkansas
Web: www.craterofdiamondsstatepark

Bring your own tools or rent them at the only diamond-producing site in the world that is open to the public. Most visitors don't get rich digging in this ancient volcanic ground, but with 40 other rocks and minerals in the area you're sure to find something interesting. Admission is $7 for adults, $4 for children.

Gem Mountain

What: Sapphires
Where: Philipsburg, Montana
Web: www.gemmountainmt.com

Gem Mountain is in the middle of nowhere, but well worth the trouble it takes to get there. Staff dig up the dirt, screen out the big rocks, and provide all the tools and equipment you'll need to wash through the gravel for rough sapphires. They'll even help you determine which stones are worth heat treating (which improves the color and clarity) and faceting. Gravel is priced by the bucket, and prices vary. Be prepared to get wet and dirty.

Herkimer Diamond Mines

What: Double-terminated quartz crystals
Where: Herkimer, New York
Web: www.herkimerdiamond.com

Nicknamed "Herkimer Diamonds" because of their striking geometrical shape, these 500 million-year-old crystals can be broken out of rocks with a hammer and chisel or collected by casually looking around the prospect area. Admission is $10 for adults and $8 for children.

Royal Peacock Mine

What: Black fire opals
Where: Virgin Valley, Nevada
Web: www.royalpeacock.com

The Virgin Valley in Northern Nevada is a stark corner of the world, but come once and you might find yourself planning a return trip. Digging isn't cheap, though. They charge $180 per person per day to dig in the fire-opal-rich bank area and $75 to dig in the mine dumps and tailings (piles of rock extracted from the mine).

Cherokee Ruby Mine

What: Rubies (plus sapphires, garnets, and moonstones)
Where: Franklin, North Carolina
Web: www.cherokeerubymine.com

At the Cherokee Ruby Mine, you're provided with a seat cushion and a screen box and shown samples of rough gemstones. Then you proceed to the flume line, where you fill your screen box and begin sluicing. This is a friendly, family-owned operation whose website lists "Mom" on a list of "Our Gems." Awww. Admission is $7 for adults, $4 for children, and shade umbrellas are available to rent for $1.

Emerald Hollow Mine

What: Emeralds
Where: Hiddenite, North Carolina
Web: www.hiddenitegems.com

Emerald Hollow Mine is the only emerald mine in the United States open to public prospecting. You'll sit at one of three sluiceways, where you can pick over buckets taken directly from the mine. It's a chance to find not only emeralds, but also aquamarines, sapphires, garnets, topaz, and amethysts. The $5 admission includes one free bucket. You can purchase additional buckets, and digging and creek prospecting are available at an added cost too.

Gold Prospecting Adventures

What: Gold
Where: Jamestown, California
Web: www.goldprospecting.com

The California Gold Rush may have been 150 years ago, but that's nothing in geological time. At Gold Prospecting Adventures families can belly up to a sluice box (which processes the buckets of gravel more efficiently than an old-fashioned gold pan) and search for flakes of gold. Guides are on hand to help, and while gold nuggets aren't guaranteed, historical nuggets are. The family price for the 3-hour Sluice Box and Pan Adventure is $155 for two adults and three children.
