The concept of birthstone jewelry, while rooted in ancient traditions, has undergone a significant transformation in the contemporary market. Modern designs often prioritize personalization and aesthetic versatility over strict adherence to historical gemological standards. A prime example of this evolution is the Anthropologie Infinity Birthstone Necklace. This piece serves as a fascinating case study in how modern jewelry manufacturers blend symbolic motifs with synthetic materials to create accessible, meaningful accessories. While the necklace is designated as a "March" variant, it is crucial to clarify that it does not utilize traditional March birthstones like aquamarine or bloodstone in its primary construction. Instead, it relies on a combination of cubic zirconia, cat’s eye stones, and resin set within gold-plated brass. This article will explore the materials, symbolism, and care of this specific jewelry category, examining how it reflects the broader trends in the modern birthstone industry.
The Evolution of Birthstone Jewelry
Birthstone jewelry possesses a rich and varied history that spans across multiple cultures and centuries. Historically, the association of specific stones with specific months was believed to confer protective and beneficial properties upon the wearer. However, in the context of modern commercial jewelry, the focus has shifted toward the aesthetic and sentimental value of the piece. The Anthropologie Infinity Birthstone Necklace exemplifies this shift. It is not merely a vehicle for a natural gemstone but a carefully constructed assembly of materials chosen for their visual appeal and durability. This piece reflects both the historical reverence for gemstones and the modern appreciation for minimalist, meaningful accessories. It stands as a testament to the enduring appeal of personalized adornment, even when the materials used are synthetic rather than natural.
Geological Formation and Materials Used
To understand the necklace, one must first understand the materials from which it is constructed. The piece is a blend of traditional and modern elements, each selected to balance cost, durability, and beauty.
The Metal Alloy The foundation of the necklace is 14k gold-plated brass. Brass is a metal alloy composed primarily of copper and zinc. It is favored in jewelry production for its malleability and workability, allowing for intricate designs like the infinity loop. To enhance its appearance and provide a barrier against oxidation, the brass is coated with a layer of 14k gold. This electroplating process deposits a thin layer of gold onto the surface, providing the luxurious finish associated with solid gold while maintaining the affordability of the base metal.
Cubic Zirconia (CZ) The necklace incorporates Cubic Zirconia, a synthetic gemstone created to mimic the appearance of natural diamonds. Chemically, CZ is zirconium dioxide (ZrO₂). It is produced in laboratory environments under controlled high-heat and pressure conditions. Gemologically, it is valued for its high refractive index and strong dispersion, which grants it a brilliance and fire that rivals natural diamonds. Furthermore, Cubic Zirconia is highly durable, rating between 8 and 8.5 on the Mohs scale of hardness. This hardness makes it resistant to scratching and suitable for everyday wear, a practical consideration for a mass-market accessory.
Cat’s Eye Stone The specific "birthstone" element in the March variant of this necklace is the cat’s eye stone. In the context of this synthetic jewelry, this refers to a man-made material exhibiting chatoyancy—a distinct band of reflected light that moves across the stone's surface. This optical phenomenon is similar to that found in natural chrysoberyl or quartz cat’s eye. The chatoyant effect, which creates a soft, glowing line, is often interpreted symbolically, representing clarity and insight. While natural cat’s eye stones are valued gemstones, the synthetic version used here provides the distinctive visual element at a fraction of the cost.
Resin Finally, the gemstones are set in resin, a synthetic polymer. Resin can be molded and shaped to fit the design, acting as a setting agent for the CZ and cat’s eye stones. While resin allows for creative flexibility, it is significantly softer than gemstones and metals. It is also sensitive to heat and ultraviolet light, which can cause yellowing or brittleness over time.
Gemological Properties of the Components
Understanding the specific properties of the materials used in the Anthropologie necklace is essential for both appreciation and maintenance. The following table summarizes the key gemological and physical properties of the primary components:
| Material | Type | Chemical Composition | Mohs Hardness | Key Characteristics |
|---|---|---|---|---|
| Cubic Zirconia | Synthetic | ZrO₂ | 8.0 - 8.5 | High refractive index, strong dispersion (fire), durable. |
| Cat's Eye Stone | Synthetic/Resin | Variable (often glass or resin-based) | 5.5 - 6.5 (est.) | Exhibits chatoyancy (light band reflection). |
| Resin | Synthetic Polymer | Organic polymers | < 3.0 | Soft, moldable, sensitive to heat and UV light. |
| Brass | Alloy | Copper, Zinc | ~3.0 | Malleable, conducts heat/electricity, prone to tarnish. |
| Gold Plating | Coating | Gold (Au) | 2.5 (pure gold) | Thin layer applied via electroplating; protects brass. |

Symbolism and Metaphysical Beliefs
The Anthropologie Infinity Birthstone Necklace is designed to carry multiple layers of symbolic meaning, appealing to the wearer's desire for connection and protection.
The Infinity Motif The infinity symbol (∞) is a powerful, universal icon representing eternity, boundless possibilities, and the cyclical nature of time. In the context of jewelry, it often symbolizes everlasting love or friendship. Its inclusion in a birthstone necklace suggests a timeless connection to the wearer's birth month and the qualities associated with it.
The Cat's Eye and Intuition As the designated "stone" for the March variant, the cat’s eye element is imbued with metaphysical significance. In various traditions, chatoyant stones are believed to enhance intuition and provide a sense of direction. The moving line of light is seen as a metaphor for seeing through illusions and gaining clarity. While the necklace uses a synthetic version, the visual symbolism remains potent for the wearer.
Birthstone Association Although the necklace is marketed for March, the use of synthetic stones rather than natural aquamarine or bloodstone shifts the focus from traditional birthstone lore to a more generalized concept of "birthstone jewelry." The value lies not in the geological rarity of the stone, but in the personal significance of the birth month itself.
Care and Cleaning Guidelines
Given the composite nature of the necklace—combining metal, hard gemstones, and soft polymer materials—proper care is critical to ensure its longevity. The differing hardness levels and chemical sensitivities require a nuanced approach to maintenance.
Storage When not in use, the necklace should be stored in a cool, dry place, ideally in a separate pouch or compartment. This prevents the soft resin from being scratched by harder items and protects the gold plating from abrasion. Exposure to direct sunlight or high heat should be avoided, as UV rays and heat can cause the resin to yellow or become brittle.
Cleaning Methods Cleaning this piece requires gentle methods that avoid harsh chemicals or abrasives.
- Gold-Plated Brass and Cubic Zirconia: These components can be wiped with a soft, lint-free cloth. If necessary, a mild soap solution and a soft brush can be used to clean the CZ, but the piece must be dried thoroughly immediately after.
- Resin Components: The resin is the most vulnerable part of the necklace. It should never be submerged in water for extended periods, as this can compromise the adhesion of the stones. Cleaning should be done with a damp cloth and mild soap only. Avoid ultrasonic cleaners and steam cleaners entirely.
- Chemical Exposure: The necklace should be the last item put on and the first taken off. Perfumes, lotions, and hairsprays contain chemicals that can degrade the gold plating and damage the resin. If the necklace is exposed to chemicals, it should be rinsed with clean water and dried immediately.
Conclusion
The Anthropologie Infinity Birthstone Necklace represents a distinct sector of the jewelry market that prioritizes design, symbolism, and accessibility. By utilizing materials such as cubic zirconia, synthetic cat's eye stones, and resin set in gold-plated brass, it offers the aesthetic appeal of fine jewelry without the associated cost of natural gemstones. While it does not adhere to the strict gemological definitions of traditional birthstones, it successfully captures the emotional and symbolic essence of personalized adornment. The piece highlights the modern consumer's desire for accessories that are not only visually appealing but also rich in personal meaning.
