Miami Beach Antique Show Spotlights Aquamarine and Spring Birthstone Trends

Ancient Roman sailors carried aquamarine as a talisman against shipwreck, believing the stone held the ocean's own power. Four thousand years later, the gemstone traveled a shorter distance to prove its endurance: the Miami Beach Convention Center, where the Original Miami Beach Antique Show closed its five-day run on March 30. The 62nd edition drew more than 600 dealers from over 30 countries, and for anyone tracking the spring birthstone market, the show's concentration of aquamarine across estate, Art Deco, and Victorian categories sent a clear signal about where retail pricing and availability are heading in the next 60 to 90 days.

The show ran March 26 through 30 at the Miami Beach Convention Center, back for its 62nd year, with inventory spanning five days of antiques, art, jewelry, and timepieces from dealers representing more than 30 countries. A live fine jewelry auction ran alongside the main floor, spotlighting antique pieces, rare gemstones, and signed jewels. Estate aquamarines appeared throughout, from Victorian rings and Art Deco brooches to vintage bracelets alongside marquee names including Van Cleef & Arpels, Cartier, Rolex, and Patek Philippe.

The birthstone angle is not incidental. March's gem dominated the spring color narrative in trade coverage leading into the show. JCK's roundup of must-have aquamarine pieces for March included an Art Deco platinum brooch from M.S. Rau set with a 10-carat aquamarine and approximately 2.15 carats of white diamonds, priced at $24,000, and an ombré fringe necklace from Renna handcrafted in 18-karat yellow gold carrying 15.6 carats of aquamarine and golden beryl alongside diamonds at $21,000. House Janolo entered the conversation with a Tetra pendant in 18-karat yellow gold featuring hand-painted enamel and an 8.3-carat aquamarine at $9,850. These retail price points reflect a stone that moves across a wide value spectrum: fine commercial-quality aquamarines run roughly $550 to $750 per carat for a one-carat stone, rising to $1,800 to $2,500 for a five-carat example and over $5,000 for stones above ten carats. At the top of the market, the finest "Santa Maria" deep blues from Brazil can fetch upward of $1,000 per carat due to their rarity, with a deep greenish-blue variety from Mozambique, known as "Santa Maria Afrique," commanding comparable premiums.

Gemval's 2026 retail market value charts confirm that aquamarine's pricing structure is unusually stable at larger carat weights: very large specimens exist in the market, which means aquamarine's value does not increase incrementally at higher carat weights, with its price per carat remaining relatively constant even in larger stones. For buyers and retailers sourcing estate aquamarines at a show like OMBAS, that stability is both reassurance and opportunity: a 15-carat estate piece does not carry the exponential premium it would in sapphire or ruby, making the gem accessible at scale for spring merchandising.

Education sessions at the show covered watch collecting, the history of jewelry, and how to incorporate antique pieces into contemporary spaces, led by field experts, with a "Tales from the Trade" panel offering direct insight into antique dealer practice. For retailers attending those sessions, the practical takeaway connects to inventory timing: spring buying trips to trade events in late March historically precede a compressed retail window. Retailers who sourced aquamarine, morganite, and pastel tourmaline at OMBAS are likely to reprice and restock within four to six weeks, making late April and May the period when consumer-facing price sheets for these stones will reflect show-floor activity most directly.

Aquamarine's position as March's birthstone meant OMBAS arrived at the precise moment of maximum retail relevance. The American Gem Trade Association highlighted new 2026 dealer offerings in aquamarine specifically prepared for spring sales, reinforcing that the wholesale pipeline is stocked and moving. Collectors watching for estate pieces with verifiable provenance, particularly Art Deco platinum settings and mid-century cocktail rings featuring the stone in its deeper Santa Maria blue, will find that post-show availability typically softens as dealers rotate sold inventory and replenish from secondary sources, a cycle that tends to resolve itself by early summer. The window to source at pre-adjustment prices is, as of this writing, already closing.
