18th Anniversary Jewelry in Sterling Silver  

Traditional Gemstones for Your 18th Year Together

Eighteen years of marriage calls for recognition beyond flowers or dinner reservations. The gemstones linked to this anniversary each hold geological interest. Cat's eye chrysoberyl forms in metamorphic rocks, its signature band created by needle-like inclusions of rutile or silk. This stone rates 8.5 on the Mohs hardness scale, making it suitable for rings and bracelets that see regular contact. Opal, softer at 5.5-6.5 Mohs, works well in pendants and earrings where it faces less abrasion. Aquamarine provides another option for couples who prefer blue tones. Mined primarily in Brazil, Nigeria, and Madagascar, this stone gets its color from trace iron content. The pale blue to blue-green hues pair well with silver settings without competing for attention. SilverRush Style has worked with natural stones since 2005. Our settings use .925 sterling silver, and we carry over 130,000 pieces across all categories. Browse rings sized for her or cufflinks for him. Each purchase ships free within the United States, and you can filter by stone type to find the traditional gem that fits your eighteenth year.
