The history of birthstones
The tradition of birthstones dates back to ancient times, with roots in various cultures and religions. One of the earliest references to birthstones can be found in the Bible, specifically in the Book of Exodus, which describes the breastplate of Aaron, the High Priest of the Israelites. The breastplate was adorned with twelve gemstones, each representing one of the twelve tribes of Israel.
Over time, the concept of birthstones evolved, with different cultures assigning specific gemstones to particular months or astrological signs. In the 18th century, the modern list of birthstones began to take shape, with jewelers and gemologists working to standardize the stones associated with each month. Today, birthstones are widely recognized and celebrated, with many people choosing to wear jewelry featuring their birthstone as a personal talisman or symbol of identity.
Interesting Anecdotes and Legends
Opal Legends and Superstitions
Opals have been surrounded by numerous legends and superstitions throughout history. One of the most famous stories involves the opal’s supposed ability to render the wearer invisible. According to legend, a thief who stole an opal from a statue in a temple became invisible, allowing him to escape undetected. However, when the opal was later recovered and returned to the statue, the thief regained his visibility.
Another well-known superstition is the belief that opals bring bad luck. This notion gained popularity in the 19th century after the publication of Sir Walter Scott’s novel « Anne of Geierstein, » in which an opal talisman brings misfortune to its wearer. The story led to a decline in the popularity of opals, with many people refusing to wear or own them. However, this superstition has largely faded, and opals are once again celebrated for their beauty and unique properties.
Tourmaline Legends and Beliefs
Tourmaline has also been the subject of various legends and beliefs. In ancient Egypt, it was believed that tourmaline passed through a rainbow on its journey from the Earth’s center, acquiring all the colors of the rainbow. This legend reflects the gemstone’s remarkable range of colors, which can vary from stone to stone and even within a single crystal.
In some cultures, tourmaline was thought to possess protective properties, shielding the wearer from harm and negative energies. It was also believed to promote healing and well-being, with different colors of tourmaline associated with specific health benefits. For example, pink tourmaline was thought to aid in emotional healing, while green tourmaline was believed to promote physical vitality and strength.
Buying Guide: How to Choose the Perfect October Birthstone
Whether you’re purchasing an opal or tourmaline for yourself or as a gift, there are several factors to consider to ensure you select a high-quality stone. Here are some tips to help you make an informed decision:
Choosing an Opal
- Play-of-Color: The most valuable opals exhibit a vibrant play-of-color, with bright, distinct flashes of color that shift and change with the angle of observation. Look for stones with a strong play-of-color and a wide range of hues.
- Body Color: Opals come in a variety of body colors, from milky white to dark black. Black opals, with their dark body color that enhances the play-of-color, are the most valuable and sought after.
- Pattern: The pattern of the play-of-color can also affect the value of an opal. Some of the most desirable patterns include harlequin (a mosaic-like pattern of color patches), pinfire (small, closely spaced flashes of color), and rolling flash (a sweeping, wave-like pattern of color).
- Clarity and Transparency: Opals can range from opaque to transparent. While some opals, such as fire opals, are valued for their transparency, most opals are appreciated for their play-of-color, regardless of their transparency.
- Cut and Shape: Opals are often cut into cabochons (domed, polished stones) to best display their play-of-color. However, they can also be found in faceted cuts, beads, and freeform shapes.
- Treatment: Some opals are treated to enhance their appearance or stability. For example, opals with a low water content may be treated with oil or resin to improve their durability. Be sure to ask about any treatments when purchasing an opal, as this can affect its value and care requirements.
Choosing a Tourmaline
- Color: Tourmaline is available in a wide range of colors, from vibrant pinks and reds to deep greens and blues. The most valuable tourmalines exhibit intense, vivid colors with high saturation. Some of the most sought-after varieties include Paraiba tourmaline (neon blue or green), rubellite (pink to red), and indicolite (blue to green).
- Clarity: Tourmaline can range from transparent to opaque, with transparent stones generally being more valuable. Look for stones with minimal inclusions (internal flaws) and good transparency.
- Cut and Shape: Tourmaline is often cut into faceted shapes, such as ovals, cushions, and emerald cuts, to maximize its brilliance and color. However, it can also be found in cabochons, beads, and freeform shapes. The cut should be proportional and symmetrical, with a good polish.
- Size: Tourmaline is available in a wide range of sizes, from small accent stones to large statement pieces. While larger stones are generally more valuable, the color and quality of the stone are more important factors in determining its worth.
- Treatment: Some tourmalines are treated to enhance their color or clarity. For example, heat treatment can be used to improve the color of certain varieties, while irradiation can be used to create unique color effects. Be sure to ask about any treatments when purchasing a tourmaline, as this can affect its value and care requirements.
Where to Buy
When purchasing an opal or tourmaline, it’s essential to buy from a reputable dealer who can provide information about the stone’s origin, quality, and any treatments it may have undergone. Look for dealers who are members of professional organizations, such as the Gemological Institute of America (GIA) or the American Gem Society (AGS), as they are held to high ethical and professional standards.
You can find opals and tourmalines at jewelry stores, gemstone dealers, and online marketplaces. However, be cautious when buying online, as it can be challenging to assess the quality and authenticity of a stone without seeing it in person. Always ask for certificates of authenticity and return policies before making a purchase.
