October Birthstone: Opal


History of Opal

Pliny was one of many authors who likened the spectacular play of color to fireworks, galaxies, and volcanoes. However, one author gave the opal a poor rap for being unlucky: In Sir Walter Scott’s novel “Anne of Geierstein,” Anne wore a golden clasp with an opal that changed color when she became energetic or disturbed. Some people disagreed with the notion that it was unlucky, contending that opals were the luckiest and most mystical jewels.

The Olympic Australis is the most expensive opal in the world. It was founded during the Melbourne, Australia, Summer Olympics in 1956 and formerly held the Guinness World Record for the largest opal. Opals are a traditional gift for a 14th wedding anniversary and a birthstone for October.

Where is Opal Found?

You can find opal as a birthstone everywhere. The world’s most producing fields for the birthstone for October are in Australia. Brazil, Mexico, and Ethiopia are all significant sources. Additional deposits have been discovered in the United States, Indonesia, Madagascar, Peru, Central Europe, Honduras, and Peru.

A little Australian village called Lightning Ridge is well known for producing valuable black opal. Lightning Ridge is a dry, rocky region that experiences little rainfall and bakes in the intense summer heat. Only a few little plants and trees help to soften it. Because of the harsh weather, miners frequently live underground to escape the oppressive heat.

Other varieties of the October birthstone come from Australia. In addition to Mintabie, Andamooka, and Coober Pedy in South Australia, white opal can also be found in the White Cliffs region of New South Wales. Queensland is the only place in the world where boulder opal is mined.

The birthstone for October is found in Ethiopia, close to the community of Wegel Tena in the Wollo Province. Opal is extracted from shafts excavated into the slope of a plateau 8,000 feet (2,400 meters) above sea level, 340 miles (nearly 550 km) north of Addis Abeba, Ethiopia. The gemstones found here have a variety of body colors, including white, yellow, orange, brownish red, and “chocolate” brown. Play of color is visible in several of the opals. In addition to orange, white, and crystal opal, another mine in Ethiopia’s Shewa Province also produces the highly sought-after black opal. Its riches are hidden beneath rocks that rise above the surrounding area.

A state in Mexico called Querétero is renowned for producing fire opal in hues of yellow, orange, and reddish-orange to red, some of which have a good color play. The mines are a popular tourist attraction, and accessing them entails traveling on a dirt route that passes through pine and oak forests, scrubby plateaus, and twisting mountain roads.

Some people think that the term “opal” originated in India, where it was known as upala, which is Sanskrit for “precious stone.” Others claim that it was first described as having a colorful appearance in Greek, where the word opallios, which means “to see a color change,” was used. It was known as an “opalus” or “precious jewel” in ancient Rome. The dance of colors in the stone, which included every hue of the most prized diamonds, was mentioned by Pliny, the Elder.

Opals were believed to possess all the powers and advantageous qualities of other colored stones for hundreds of years due to their colorful array. Romans called it the Cupid Stone, and considered it the most valuable and potent stone and a representation of love. Because of this, it might inspire passion and romance. It has stood for honesty, purity, and optimism for a very long time.

Arab nomadic tribes thought the opal, which contained lightning, fell to Earth during thunderstorms. Ancient Greeks thought opal possessed the gift of prophecy—the capacity to predict the future.

Opals have a 5.5 to 6.5 Mohs Hardness grade, making them scratch-prone and more appropriate for special events than daily wear. However, despite the extra care needed to clean and secure it, opal jewelry’s versatility and beauty make it worthwhile. Keep opal jewelry separate from other gems in storage to avoid damage.

Make use of warm, soapy water to clean opals. Other techniques—particularly in opal doublets and triplets, manufactured stones where opal pieces adhere together—can harm your opal or the filler material used.

Be aware that opal triplets and doublets’ adhesives may weaken after prolonged exposure to water. Intense heat or sharp temperature changes can cause even natural opal to fracture.

On the Mohs scale, the hardness of the birthstone for October ranges from 5 to 6.5. Opal should be stored alone to avoid scratches from jewelry sets with harder gems. Only a select few gemstones, such as emeralds, sapphires, rubies, and diamonds, can rival the October birthstone.

Cost of Opal

The average cost of opal can vary greatly depending on several fast one’s factors, including the type and quality origin of the stone. Opals come in various varieties, such as black, white, boulder, and fire, each with unique characteristics. Additionally, factors like color play, clarity, and the presence of any imperfections can affect the price.

On average, opals can range from a few dollars per carat for lower-quality stones to several hundred or even thousand per carat for high-quality, rare opals. It’s important to note that larger, higher-quality opals with vibrant colors and patterns tend to be more valuable and command higher prices. As with any gemstone, you should consult a reputable jeweler or gemologist to get a more accurate and specific understanding of opal prices based on your preferences and requirements.

October Birthstone: Tourmaline


History of Tourmaline

Tourmaline was frequently confused for other gems due to its vast range of colors. Notably, the pendant of Caesar’s Ruby is found in the Russian crown jewels. Tourmaline was mistaken for other gemstones before being identified as a distinct mineral species for many years. Through heat and pressure, tourmaline can become electrically charged, at which point it can oscillate and collect dust particles like a magnet.

China was one of the biggest markets for tourmaline at the beginning of the 20th century. The tourmaline trade declined with the collapse of the Chinese government in 1912. You can give tourmaline to commemorate an eighth wedding anniversary.

Where is Tourmaline found?

The gemstone for October is most frequently found in Brazil, although it is also mined in other African nations like Afghanistan, Pakistan, Kenya, Madagascar, and Mozambique. Fine tourmaline is historically produced in large quantities in California and Maine.

Pegmatites in Minas Gerais have provided most of the tourmaline mined in Brazil over the years. A true kaleidoscope of gem minerals is produced due to these subsurface magma intrusions. However, electrifying green, blue, and violet tourmalines from pegmatites in Brazil’s Paraba State reached the gem market in the late 1980s. Researchers discovered that trim levels of copper, which had not before been identified as a coloring factor in any other tourmaline, were responsible for the intense colors. Tourmalines of the Paraba type that contain copper were also found in Mozambique and Nigeria in the early 2000s. Overall, due to their vibrant colors, more substantial color saturation, and increased rarity, the greatest Paraba and Paraba-type tourmalines are easily more expensive than others.

Southern California and Maine are home to several pegmatite districts in the United States. They have sporadically produced significant amounts of tourmaline for over a century. Two young boys exploring the area found Mount Mica near Paris, Maine, around 1820, where Maine’s first significant tourmaline deposit was found. A Mount Mica quarry continues to produce gem tourmaline in various colors sporadically. Maine’s most frequent source of tourmaline is the Dunton mine, which is close to Plumbago Mountain.

In the Mesa Grande region, known for producing exquisite rubellite, the Himalaya pegmatite saw the opening of California’s first commercial tourmaline mine in 1898. 120 tons of gem rubellite were shipped to Imperial China by San Diego mines between 1902 and 1910 to satisfy Empress Dowager Cixi’s infatuation with the vivid color. With the death of Cixi in 1908 and the fall of the Qing empire, California’s tourmaline mining era ended. Today, gem-quality tourmaline is only sporadically produced in a few mines in San Diego County.
