The Florentine diamond shares a common fate with the Bazu and the Sancy—it was stolen from its last known owner, a member of the Austrian Imperial family, and never recovered. However, you can count this yellow double rose-cut stone as part of your collection with a museum-quality replica from The Stonecutter.

The Florentine is a nine-sided, 126-facet diamond. Specifications for the Florentine replica are based on drawings and weight reported by Tavernier.

Florentine History

Like many famous diamonds, the history of the Florentine is disputed. Some sources indicate that Charles the Bold, Duke of Burgundy was one of the earliest owners. After falling in battle, a peasant or foot soldier took the stone and sold it cheaply, thinking it was glass. From this sale, the stone made its way through a couple of Swiss owners and finally became part of the Medici treasury in Florence (hence its name).

Other sources, however, trace the stone from a king in southern Indian to a Portuguese count. The stone was held by Jesuits until negotiations were finalized with the Grand Duke of Tuscany.

Historical documents do not authenticate the Florentine’s history until 1657 when Tavernier saw the stone in the Grand Duke’s collection. When the last of the Medicis died, the stone was passed onto the Austrian Habsburg family (via marriage of Francis III Stephen to Empress Maria Theresa). The Florentine became part of the Austrian Crown Jewels and was carried with Charles I into exile after the fall of the Austrian Empire in WWI. Someone close to the imperial family is believed to have stolen it around 1918. While the whereabouts of the stone are unknown, it has been rumored that the Florentine was brought to the US in the 1920s.

Replicating the Florentine

There are three different versions of models and measurements of the Florentine, but none of them provide all the information needed to replicate the stone. To determine the angles of the upper and lower halves of the Florentine, The Stonecutter had to painstakingly calculate values based on information that was available—the weight, the specific gravity and the drawings. Scott Sucher relied upon historical information from Tavernier, whose accounts have proven accurate for a number of other historic diamonds. It took three years to develop the equation and solve it to derive the two primary angles, as this was prior to the advent of the personal computer and gem design software. However, this time was not wasted, as it took three years for the factory to create a piece of rough large enough to cut the replica.

The care The Stonecutter invests in acquiring the most precise specifications assures that you get a replica of the highest quality. Order yours online, and contact us for jeweler recommendations to set the stone.
