Beryl is both popular and exciting.

It’s a category of mineral, one that you see in a variety of color combinations.

Did you know, for example, that Emerald, a precious gem, is a form of beryl?

Now, to be clear, a lighter green beryl is simply “green beryl,” since it isn’t as crisp and lovely as emerald.

Aquamarine is another type of beryl.

Other awesome examples of Beryl are pink morganite, the yellow Heliodor and Golden Beryl.

Red beryl is quite rare, and fetches a good price.

The basic—or pure—form of beryl is clear and naturally transparent.

Beryl has a nice hardness score of 7.5 – 8, but it’s also brittle, meaning one has to be careful using it in a ring.

Beryl has a very long history: Pliny the Elder, a Roman naval commander and writer, used it to cure spine and eye injuries, as well as heart problems. T

oday, on a more spiritual side, it can help one stay youthful and can help marital love.

Most Famous October Birthstone: Opal

What makes the opal so treasured and wonderful is its flash of light—it’s right up there with the diamond in that regard.

Also, it can flash colors all over the spectrum.

Now, that last trait isn’t as true of the “Common Opal,” which doesn’t have that play of light. But the common opal is still a stunning gemstone.

A super-smooth stone with mixed colors: pink, blue, light purple and a mossy green.

It often has mineral inclusions that cause white markings to criss-cross the gem.

The fire opal is another variety, and these look quite a bit different from other opals.

Fire opals can be a fiery red, plus varieties of orange.

Opals are 5-6 in hardness, with a wide variety of lusters.

Opals bring a full spectrum of light, and allow people to sort through their emotions.

That is due to the opal’s high water content.

It’s a perfect birthstone for October, since it comes in a colorful variety to match what Mother Nature gives us during that time.

Opals and tourmalines both feature a kaleidoscope of colors, but Tourmalines are more vibrant.

The name “tourmaline” comes from the Sinhalese words “tura mali” (or from the word toramalli).

Everybody knows the pink tourmaline, but tourmalines come in so many other colors like green, red or blue. In fact, many tourmaline stones are multi-colored.

Technically, tourmalines are a whole group of minerals with similar properties.

Tourmalines usually rate 7-7.5 on the mohs scale, and that kind of toughness is refreshing to find in a stone that isn’t expensive.

Be careful: look out for fake tourmalines.

If you spot, via microscope, a slice of tinted glass glued between stone, you have an imitation.

You can have a jeweler safeguard against this.

There are different types of jaspers, including morrisonite, agate, jaspilite, Morgan Hill, leopard, Deschutes, Egyptian—and that’s to name just a few.

Precious coral is usually warm pinkish to red, yet sometimes medium-red to rich ox-blood red.

Noble coral exhibits a great uniform color, though sometimes with streaks or spots of white or pink.

It usually scores about 2-3 on the hardness scale, so it’s not a workhorse type of jewelry.

However it is a symbol of wisdom, fulfillment and long life. Further, coral remedies insomnia, spasms in the intestines, and bladder stones.
