The 7mm gemstone stud earring is a popular choice for everyday wear and gifting, offering a subtle yet elegant display of color and sparkle. This size is frequently used for birthstone jewelry, allowing for a noticeable presence without being overly ostentatious. Several gemstones are commonly featured in 7mm stud settings, each with its own unique history, properties, and symbolism. This article will explore the characteristics of amethyst, garnet, emerald, and cubic zirconia as they appear in this popular jewelry format, drawing exclusively from available sources.
History and Lore
The tradition of associating gemstones with specific birth months has ancient roots, evolving from early beliefs in the protective and influential powers of gems. Sources indicate that gemstones were historically worn not only as adornments but also as a form of “armor,” believed to offer protection, calm, or guidance to the wearer. This practice predates modern birthstone lists, with connections to the zodiac and calendar months developing over time. While the specific origins of the modern birthstone list are not detailed in the provided sources, the enduring appeal of these associations is highlighted by David Yurman’s emphasis on the “personal power” and “symbolism” inherent in birthstone jewelry. The practice of gifting birthstones remains a meaningful way to honor individuality and celebrate milestones.
Geological Formation and Sources
The provided sources do not detail the geological formation of the gemstones themselves, nor do they specify primary mining locations. However, they do indicate the availability of both natural and lab-created options. For example, 7mm princess-cut earrings feature lab-created white sapphires, noted for possessing the same physical and chemical properties as their natural counterparts but at a lower cost. Similarly, amethyst and garnet are presented as natural gemstones, while emeralds are available as lab-created stones. The sources emphasize responsible sourcing of materials, suggesting an awareness of ethical considerations within the gemstone industry.
Gemological Properties
The 7mm size is a consistent feature across several gemstone options. The sources provide specific details regarding cut, clarity, and carat weight for certain stones. Princess-cut gemstones measure 7mm (approximately 2.5 carats), while round cuts also commonly appear at this size. Lab-created white sapphires are noted for their “excellent clarity, sparkle and color.” Emeralds, when lab-created, are DEF in color and VS+ in clarity, indicating high quality. Garnet is described simply as a natural gemstone, without further specification of its properties. Cubic zirconia, used in silver settings, is designated as AAA quality.
A comparison of hardness, based on general gemological knowledge (though not explicitly stated in the sources), would place these stones in the following order (from hardest to softest):
| Gemstone | Mohs Hardness |
|---|---|
| Cubic Zirconia | 8.5 |
| White Sapphire | 9 |
| Emerald | 7.5 - 8 |
| Amethyst | 7 |
| Garnet | 6.5 - 7.5 |
