The story of the design
A classic design elevated by natural luster and craftsmanship, this Black Agate Double Strand Necklace embodies timeless sophistication. Each smooth, round bead—measuring between 7mm and 9mm—is hand-selected and individually knotted on durable silk cord to ensure even spacing, flexibility, and strength. The result is a strand that drapes with perfect weight and presence, showcasing the deep, mirror-like polish of genuine black agate.
At 34 inches in length, this piece offers versatile styling—elegant when worn long, or easily doubled for a layered, statement look. The uniform bead gradation and secure finish reflect refined workmanship suitable for both everyday wear and formal occasions.
