The world of gemstones offers a dazzling array of choices, each with its unique history, geological origins, and aesthetic appeal. While many birthstones boast ancient lineages and global mining locations, some gems are intimately tied to specific regions, offering a unique connection to the land. This article explores two such gemstones – Emerald Obsidianite and Oregon Sunstone – both prominently featured by jewelers in Portland, Oregon, and each possessing distinct characteristics and metaphysical properties. While not traditionally recognized as August birthstones across all historical accounts, these gems are gaining recognition and popularity, particularly within the Pacific Northwest.
A Legacy of Craftsmanship in Portland
Portland, Oregon, has a rich history as a center for gem and jewelry artistry. For over three decades, businesses like The Fossil Cartel have cultivated a deep inventory of high-quality gemstones, evolving from a small cart to a prominent storefront in the historic Gilbert Building. This dedication to quality and craftsmanship provides a unique setting for appreciating gems like Emerald Obsidianite and Oregon Sunstone. The Jeweled Crescent also contributes to the city’s reputation, offering custom designs and pieces evaluated by a certified Gemological Institute of America (GIA) gemologist.
Emerald Obsidianite: Born of Fire and Fury
Emerald Obsidianite is a relatively recent addition to the world of gemstones, its origins directly linked to the dramatic eruption of Mount St. Helens in 1980. The eruption unleashed a torrent of pulverized rock, which, when heated, fuses into a translucent stone exhibiting a striking emerald green hue. This unique material is often described as a “bonafide piece of Mt. St. Helens,” offering a tangible connection to a significant geological event. A variation, Twilight Obsidianite, also exists, displaying a color-changing property – appearing light blue under fluorescent light.
The formation of Obsidianite is a fascinating process. The intense heat from the eruption causes the rock fragments to melt and rapidly cool, resulting in a volcanic glass. The emerald color is a result of the specific mineral composition and the conditions under which it formed. This gem is not a traditional obsidian, but a unique material created by the specific circumstances of the 1980 eruption.
Oregon Sunstone: A Sparkling Treasure
Oregon Sunstone, officially designated as Oregon’s state gemstone, is a unique variety of gem-quality feldspar found in south-central Oregon. Unlike sunstones from other locations, Oregon Sunstone contains copper inclusions, which create a distinctive sparkling effect known as schiller. This schiller is a key characteristic, differentiating it from other feldspar varieties. The color range of Oregon Sunstone is diverse, encompassing pale yellow, orange, pink, red, and even shades of blue/green, all dependent on the copper content.
The Fossil Cartel specializes in Oregon Sunstone, offering a large selection of this locally sourced gem. The gem’s appeal lies not only in its visual beauty but also in its metaphysical properties, believed to promote self-empowerment and vitality.
Gemological Characteristics
While detailed gemological data like refractive index or specific gravity are not provided in the available sources, some characteristics can be inferred.
Emerald Obsidianite: As a volcanic glass, Obsidianite lacks a crystalline structure. Its hardness is moderate, typical of glass, making it susceptible to scratching. The color is a consistent emerald green, and its translucency allows light to pass through, enhancing its visual appeal.
Oregon Sunstone: Being a feldspar, Oregon Sunstone exhibits a vitreous luster. The presence of copper inclusions affects its hardness and cleavage, though specific values are not provided. The schiller effect is a key identifying characteristic, creating a dynamic play of light within the stone. The color range, from pale yellow to red, offers a variety of aesthetic options.
Here's a comparative table summarizing the key characteristics:
| Feature | Emerald Obsidianite | Oregon Sunstone |
|---|---|---|
| Composition | Volcanic Glass | Feldspar |
| Color | Emerald Green | Yellow, Orange, Pink, Red, Blue/Green |
| Luster | Vitreous | Vitreous |
| Schiller | No | Yes |
| Crystal System | Amorphous | Triclinic |
| Origin | Mt. St. Helens, WA | South-Central Oregon |
History and Lore
The history of Emerald Obsidianite is inextricably linked to the 1980 eruption of Mount St. Helens. Its discovery and subsequent use in jewelry are relatively recent, making it a contemporary gemstone with a unique origin story. The gem’s appeal lies in its connection to a powerful natural event and its vibrant color.
Oregon Sunstone, while known to Native American tribes for centuries, gained prominence as a gemstone in the 1970s. Its designation as the official state gemstone of Oregon in 1987 further solidified its importance. The gem’s metaphysical properties, associated with vitality and self-empowerment, add to its cultural significance.
Symbolism and Metaphysical Beliefs
Oregon Sunstone is specifically noted for its metaphysical properties, believed to promote self-empowerment and vitality. While no specific metaphysical beliefs are detailed for Emerald Obsidianite in the provided sources, its origin from a volcanic eruption could be interpreted as symbolizing transformation and resilience.
Jewelry and Design
The sources highlight the versatility of both gemstones in jewelry design. The Jeweled Crescent showcases a spectacular emerald-cut Indicolite Tourmaline and Diamond Ring, demonstrating the artistry and craftsmanship available in Portland. The Fossil Cartel offers a range of jewelry featuring Oregon Sunstone, including pendants, earrings, and rings. The availability of both loose gemstones and finished pieces allows customers to choose from a variety of styles and designs. Cameos, experiencing a resurgence in popularity, are also featured, drawing inspiration from historical designs and royal traditions.
Care and Cleaning
Due to the lack of specific hardness data, general care guidelines for glass and feldspar apply. Emerald Obsidianite, being a glass, should be protected from scratches and impacts. Cleaning can be done with mild soap and warm water, avoiding harsh chemicals. Oregon Sunstone, as a feldspar, is relatively durable but should still be handled with care. Gentle cleaning with a soft cloth and mild soap is recommended.
Purchasing in Portland, Oregon
Portland, Oregon, offers a unique opportunity to acquire these gems directly from local jewelers. Businesses like The Jeweled Crescent and The Fossil Cartel provide a curated selection of high-quality pieces, often with the added benefit of custom design services.

Emerald Obsidianite and Oregon Sunstone represent a unique facet of the gemstone world, offering a connection to the geological history and artistic craftsmanship of the Pacific Northwest.
