"Draw down the tides and wear the sky—this is the moon, caught mid-spell."
The Nereus Moonphase ring captures lunar magic in motion, etched with each phase of the moon and filled with deep ultramarine opal that glimmers like a restless sea under starlight. By day, it reflects oceanic blues; by night, it comes alive—glowing electric blue in the dark. It’s a tribute to cycles, mystery, and the balance between stillness and surge.
Material: Titanium
➤ Oceanic. Luminous. Enduring.
The clean brushed titanium band creates a crisp silhouette, offering a modern frame for the moon’s shifting face. Sleek, strong, and timeless, this piece reflects both the depth of the sea and the glow of the cosmos—day or night.
How It's Made
Here's a quick video that shows what goes into making our rings. We hand craft each ring in house made specifically for you. We use the highest grade carbon fiber, ultra pure epoxy that has been cured and post cured for maximum strength, super bright glow and high grade materials across the board.
