The Duchess of Calabria’s Ruby Tiara - Bourbon-Two Sicilies Royal Crown

Duchess of Calabria's Ruby Tiara

The Calabria Ruby Tiara is a distinguished example of nineteenth-century floral jewelry, representing the artistic and dynastic heritage of the House of Bourbon-Two Sicilies. Manufactured during an era when botanical naturalism was the pinnacle of European fashion, this headpiece is celebrated for its intricate craftsmanship and the vivid chromatic contrast between its precious gemstones.

Architectural Design and Floral Naturalism

The diadem is designed as a delicate, sweeping floral spray, a style that prioritizes organic movement over the rigid, vertical geometry of traditional state crowns. Its structure is a masterful arrangement of diamond-encrusted foliage and ruby-set blossoms, set in a traditional combination of gold and silver to provide both structural integrity and a luminous backdrop.

• The Ruby Blooms: The primary focal points of the diadem are several stylized flowers, each centered with a vibrant, round-cut ruby. These rubies serve as the "heart" of the blossoms, their deep red saturation providing a warm, regal counterpoint to the cool brilliance of the diamonds.
• Diamond Foliage: The framework consists of intricate leaves and stems pavé-set with diamonds. These elements are engineered to arch and curve naturally, mimicking the appearance of a wild vine or a gathered bouquet.
• The Silhouette: Unlike the towering, architectural silhouettes of the mid-1800s, the Calabria Ruby Tiara possesses a lower, more graceful profile. This design ensures the piece is versatile, complementing the various hairstyles favored by royal women across the nineteenth and twentieth centuries.

Versatility and Conversion

In keeping with the sophisticated jewelry engineering of its era, the Calabria Ruby Tiara was designed to be modular. The piece is built upon a convertible frame that allows it to be dismantled into several smaller components:

• The Brooch Configuration: The central floral motifs can be detached from the main tiara structure. This allows the wearer to utilize the ruby blossoms as independent brooches or hair pins for less formal evening receptions.
• Aesthetic Adaptability: Because the floral sprays are arranged in distinct sections, the tiara can be adjusted to sit more open or closed on the head, depending on the preference of the wearer and the specific requirements of the event.

Provenance and Dynastic History

The tiara is a central heirloom of the Calabria branch of the Bourbon-Two Sicilies family. It was most famously associated with Infanta Alicia of Spain, Duchess of Calabria, who was a pivotal figure in European royalty throughout the twentieth century. As a member of the Spanish royal family by birth and the Italian Bourbon line by marriage, Alicia curated a vast collection of historic jewels, of which the Ruby Tiara was a cherished highlight.

Throughout the decades, the piece has transitioned through subsequent generations, including Princess Anne of Orléans and the current Duchess of Calabria, Sofia. It is frequently selected for royal weddings and state banquets, where its romantic aesthetic provides a soft yet majestic presence.

Recent Context (Late 2025)

As of December 2025, the Calabria Ruby Tiara remains a protected asset within the family’s private collection. Most recently, it was worn during a diplomatic gathering in November 2025, where historians noted its impeccable preservation. It stands as a shimmering link to the vanished courtly life of the nineteenth century and remains a testament to the enduring appeal of the floral "spray" style.
