October Birthstones

October birthstones: Opal, Tourmaline, and More

Anyone who likes color will be thrilled with the selection from October's Birthstones. In addition to the traditional birthstones for the month, there are also many Zodiac and Planetary Stones to choose from which relate to October as well. If we are talking about the modern-list Opal and tourmaline are the birthstones for October.

Opal Birthstones

More than any other gem, each opal is distinctly an individual. No other stone has as rich and varied a folklore. Opals are also the most delicate gems commonly worn. They require special care to ensure their health and longevity. Of the opal varieties, there are numerous color options from which to choose. Boulder Opal, Opal, Fire Opal, Opal Doublet, Black Opal, and Chocolate Opal are all appropriate to wear as traditional birthstone jewelry.

Tourmaline Birthstones

Tourmaline derives from the Sinhalese term "turamali", which translates as "stone of mixed colors". The very name refers to the unique spectrum of colors displayed by this gemstone, which is second to none in the realm of precious stones. One of the most versatile of gemstones, tourmaline is available in every color, from colorless to black. It can show every tone from pastel to dark, and can exhibit various colors in the same stone.

Tourmaline is a group of minerals that can appear in many colors based on the elements that are present in its chemical composition. Because of this, many solid colors and color combinations are available to shop.

Black Tourmaline or Schorl

Black Tourmaline or 'Schorl,' are iron-rich varieties that can vary slightly in color. Black Tourmaline is widely available and very affordable it is also known as a protective stone that can shield its wearer from toxins, anxieties, and radiation.

Brown Tourmaline or Dravite

Brown Tourmaline which is also known as Dravite is a variety that is rich in magnesium. This variety can change in color from brown tones to yellowish colors too.

Elbaite Tourmaline Group

These varieties are the most popular varieties because of the vast array of colors they can exhibit. Elbaite Tourmaline contains lithium and coloring elements that are responsible for the appearance of the different shades of Tourmaline.

Red Tourmaline or Rubellite

This variety of Tourmaline gets its color from manganese; however, some pieces with less intense color and similar chemical compositions may classify as Pink Tourmaline

Blue Tourmaline or Indicolite

Indicolite or Blue Tourmaline can also vary in color as it is possible for the variety to display hues from blue to bluish green which is dependant on iron and titanium content.

Green Tourmaline or Verdelite

This variety, often called Chrome Tourmaline because the color is caused by Chrome and Vanadium.

Purplish and Greenish Blue Tourmaline or Paraiba

Paraiba Tourmaline is a vivid colored Tourmaline which comes from Paraíba, Brazil. Of the Tourmaline gem family, this variety is the latest to be discovered.

Bi-color or Multicolor Tourmaline

Bi-color and Multicolor Tourmaline live up to their name by displaying multiple hues in a single piece. Pieces of Tourmaline like this are formed by chemical changes that occur during the crystallization of the Tourmaline itself. These samples are scarce and desirable.

Additional birthstones for October

The astrological stone for Scorpio is beryl. Beryl is one of the most important mineral groups and also one of the biggest gemstone groups. Although the mineral is abundant, it rarely occurs in transparent gem-quality material. Transparent gem-quality beryl is referred to as 'precious beryl'. The most famous beryl gemstone is green emerald, followed by blue aquamarine. Golden beryl is not very well-known by the general public. Other popular beryl gems include pink 'morganite' and white, or colorless, 'goshenite'. Red beryl is the rarest variety of beryl and it is known in the trade as 'bixbite'.

I love GemSelect! Every stone that I ever purchased has been carefully packaged, and sometimes comes with origin info. The stone I just ordered is for my engagement ring, because my Fiance is making my ring! I am so amazed with the selection that this site has, and I am so impressed with the prices.
