Vintage Octagon Halo Round Aquamarine Ring in Sterling Silver

This aquamarine ring is a vintage-inspired halo engagement ring in 925 sterling silver with a rhodium finish, built around a 0.85 carat natural round brilliant aquamarine framed by an octagon halo of baguette and round simulated diamond accents. The Art Deco geometry of the halo gives the cool sea-blue aquamarine serious architectural presence — the kind of silhouette that could have come out of a 1920s jewelry box, built for daily wear at a fraction of the estate-jewelry price.

The Aquamarine

• 100% natural aquamarine — genuine beryl, mined and cut, not lab-grown or simulated
• Round brilliant cut, 6.0 mm, approximately 0.85 carat — the most light-returning cut possible, showing off aquamarine's signature clarity and cool blue color
• Mohs 8 hardness — durable enough for daily engagement-ring wear
• March birthstone — traditionally a symbol of calm, courage, and safe travel across water

The Setting

• Octagon halo framing the round center — an Art Deco geometric shape that's rare in modern bridal jewelry, built from alternating baguette and round CZ accents
• Four baguette-cut simulated diamonds at the cardinal points of the octagon create strong architectural lines
• Round simulated diamonds fill the halo's corners and trace the pavé shoulders
• Six-prong basket securing the round center stone — more prongs than a standard four-prong, for extra security
• Halo size: 10.5 mm — substantial finger presence

The Band

• 925 sterling silver with rhodium finish — hallmarked fine-jewelry metal plated with rhodium for a bright white-gold appearance and added tarnish resistance
• 2.3 mm average band width — substantial enough to hold the halo, slim enough to feel delicate
• 100% nickel-free and hypoallergenic
• Comfort-fit interior rounded for smooth all-day wear

Why Natural Aquamarine

• Real mined beryl — the same gem species as emerald and morganite, in its signature cool blue variety
• Clean, transparent color without the heavy inclusions of most natural colored stones at this carat weight
• Ethically sourced natural gemstone
• Not lab-created, not simulated, not dyed — this is the actual natural stone

Who It's For

• Brides drawn to colored-stone engagement rings over traditional white-diamond solitaires
• Anyone born in March (aquamarine is the March birthstone) or celebrating a 19th anniversary
• Partners shopping for a vintage aquamarine engagement ring without the estate-jewelry price tag
• Women drawn to Art Deco, Edwardian, or Old Hollywood aesthetics
• Buyers who want the clear cool blue of aquamarine against bright white fire — one of the most classically elegant color pairings in fine jewelry
