Marina B Trisolina Ruby & Diamond Collar Necklace in 18K Yellow Gold

Product Insights & Style Tips

There’s an unmistakable boldness to the Marina B Trisolina Collar Necklace—a power piece with that intoxicating ’80s decadence, reimagined for the modern maximalist. Meticulously composed of 18K yellow gold, it’s accented with rubies and diamonds that flash with every turn, catching light in a way that feels both unapologetically luxe and utterly wearable. The Trisolina’s geometric, sculptural curves echo Marina B’s signature heritage, balancing sharp lines with opulent color: think heirloom quality, but with the kind of drama that anchors an entire look.

The collar silhouette sits confidently along the neckline, tracing the collarbone with subtle weight and undeniable presence—never heavy, just substantial enough for comfort and impact. Flexible construction allows it to contour smoothly to the wearer, holding its shape while still moving with you. The seamless closure and smooth finish prevent snagging, making it easy to slip on as the last, transformative layer—over a crisp white shirt for day or bare skin on a night out. Built-in brilliance from the diamonds and rubies means you can pare everything else back; this necklace carries itself—and your essentials—effortlessly from gallery afternoons to rooftop evenings, no overthinking required.

If you’re watching the pendulum swing back to head-turning jewelry—see: recent runways and street style—the Trisolina feels spot-on. Marina B pieces consistently embody that rare mix of Italian glamour and contemporary edge, and this necklace serves as a collector’s statement: vintage in spirit, storied in execution, and ready to redefine what a “classic” means right now.
