Description
MARETTIMO is a necklace with quiet power — unmistakably luxurious without trying too hard. Seventeen finely aligned strands of deep black onyx create a rich, fluid volume that sits like silk around the neck. The effect is calm, polished, and intensely refined.
Its signature comes from the natural focal point: a marble cone shell, paired with an onyx cabochon, bringing sculptural elegance and organic contrast to the sleek darkness of the onyx. The balance of marine form and gemstone minimalism gives this piece real character — it feels designed, not just assembled.
At 55 cm, MARETTIMO falls beautifully for open necklines, clean tailoring, and evening looks. The clasp in sterling silver, 18k gold-plated, adds a refined finish and secure wear.
As with every SONNIA creation, this necklace is individually handcrafted, and can also be made in yellow or white gold upon request (price on request). MARETTIMO is for those who want timeless luxury with presence — elegant, bold, and unmistakably high-end.
