DirectionItalian Technical

What We Make

Three output types.

Three output families. The same study method, different lead times and thresholds.

Parures

Coordinated sets of 3 to 5 pieces sharing one principal stone or one technical language. Ring, earrings, necklace, bracelet, possibly a brooch. The client decides which pieces to include.

II.

One-of-a-kind

One-of-one pieces designed around a principal stone selected together. Brooches, pendants, cocktail rings, evening earrings. The piece is signed and never re-enters the catalogue.

III.

Ceremonial pieces

Tiaras, diadems, crowns. Specific structural systems: titanium core, articulated joints, safety closures. Full photographic documentation for archive and insurance.

Reproducibility

Not on the principal stones. Yes on the architecture.

The principal stones in the pieces shown are unique and cannot be replicated. What can be reproposed is the language of the collection. Yellow gold corolla, polychrome pavé of orange sapphires, spessartite, black diamonds. On alternative principal stones selected together at brief stage.

Possible substitutions on the Lava collection: rubellite, paraiba tourmaline, red spinel, mandarin garnet, morganite, tanzanite. On the Orchid brooches: the pavé can be reproduced on an alternative design, in white or rose gold, with a colour palette adapted to the client. The Butterfly can also be requested at reduced scale (5–6 cm) or in a monochrome palette (champagne only, brown only, white only). On the Flora collection. The Iris and Duet rings. The colour gradient of the pavé is fully customisable: the iris's violet sapphires can become fuchsia-pink, green (tsavorites), or yellow; the duet can be requested in yellow or rose gold with stamens in orange sapphires or rubies.
