How To Style
Sits high on the neck, often referred to as choker length. Style solo or layer with longer necklaces for a statement stack.
Short necklaces are one of our most common necklace lengths, designed to fall on the base of the neck. This is a versatile length to kick start your necklace collection.
Another common necklace length, medium necklaces are designed to fall on or below the base of the neck. This length is perfect for pairing with your favorite charms and pendants.
Long necklaces are designed to sit just above the chest. This length plays perfectly with an open neckline, added necklace layers, and personalized charms or pendants.
24" The longest standard necklace length, these pieces are designed to drape elegantly at or just below the chest. Ideal for creating depth with layered looks or making a bold statement with a singular piece.
Inspired by bold lines and elegant shapes, this pendant showcases a striking Natural Black Onyx framed with delicate gold-plated detailing. Enhanced by a brilliant White Zircon, it brings together geometric beauty with a touch of sophistication. Perfect for layering or as a statement piece on its own.
