October Birthstone Report: Opals and Tourmaline

October babies: you buncha’ lucky ducks. Did you know that you get to choose between two gemstones for your birthstone? Oh, and each of these gemstones come in multiple colors. Talk about options for October!




Option 1: Opals

Opals are the original birthstone for the month so if you’re looking for a more traditional pick, this is your best bet. The characteristic most valued in an opal is its play-of-color – the variation of hue within the gemstone that reflects differently according to the light and angle.

There are five main categories of opal, each with its own alluring characteristics. White or light opals are the most popular, showing a translucent or semitranslucent sheen with play-of-color against a white or light gray body color. Black opals are translucent to opaque and, as expected, have a play-of-color against a black or dark background. Fire opals (or, “Mexican opal” in some circles) show a brown, yellow, orange, or red body color and often don’t show play-of-color at all. Boulder opals are fascinating cuts that show fragments of the surrounding rock, called the “matrix”, which become part of the finished gem. Finally, water opals are highly valued for their rarity and show a transparent to semitransparent, with a clear background, and shows an exceptional play-of-color.

Opals have long been regarded as containing supernatural powers. Ancient Arabic tribes believed that it falls from the sky in flashes of lightning, and ancient Greeks believed that the gemstone afforded wearers prophetic talents and guarded them from disease. For centuries Europeans believed that opals were symbolic of hope, purity, and truth, though in the last two hundred years the gem gained a reputation for being unlucky to wear if you are born outside the month of October. So, if you’re a particularly superstitious October baby, know this: you’re in the clear to wear as many opals as you well please.




Option 2: Tourmaline

If opals aren’t your thing, you’re in luck: tourmaline is an alternative that may suit your style. Tourmaline is a semi-precious gem that comes in a wide variety of shades. This gemstone can be cut into virtually any shape and it’s a relatively durable option if the fragility of opals scares you. You may have heard of its pink-red variety, “rubellite”, the finest of which displays a beautifully saturated hue that virtually glows. The highest valued variety, Paraiba tourmaline, owes its amazing chromatic display to the presence of copper in the mineral. While Paraiba tourmaline historically has been mined exclusively out of the state of Pariaba, Brazil, more recently deposits have been found in other countries such as Mozambique and Nigeria.

Tourmaline has been set in jewelry for centuries but until the 1800s it was more commonly mistaken as other colorful gemstones such as emeralds, sapphires, and rubies. Today you can find lovely varieties mined from Maine and California as well as Afghanistan and Madagascar. If you’re lucky to travel to one of its many sources, consider picking up a loose gemstone if you can. Look for even saturation, allow for some inclusions, and use an expert local resource if at all possible: this gemstone is often mimicked with synthetic impersonators, so don’t fall prey to unscrupulous gemstone dealers!

I came to join Alexandria & Company by way of love: my husband Tim has owned the stop for nearly ten years, and I started by helping him on Saturdays so that we could spend more time together. Eventually, I quit my other life in the legal field to become Alx&Co’s Creative Director and co-owner with Tim. Now, we run our small business together in Old Town and I haven’t looked back.
