Elemental reading: Metal

Metal begets water: silver-white is metal's own color among the five phases, and the coiled band embraces a stone the shade of deep water — black being water's hue. The serpent's circle returns to itself, first and last.

Yin · Yang — Coiled silver band = yang (bright, outward, moving); black diamond = yin (still, deep, absorbing). One circle holds both.

The Stone — Ink of the Night Sky

A 2.5 ct black marquise, 8 × 4 mm, cut from meteoritic black diamond — carbonado, the darkest form of carbon. In lamplight it opens into deep blue-black fire, ringed by white moissanite like stars at the edge of night.

The Serpent — a Circle Sealed

The band coils once around the finger and ends where it begins — the ouroboros, drawn by alchemists and jewelers for two thousand years as the sign of what never ends. Its scales are white moissanite, set one by one down the silver spine.

Good to know

What is a meteoritic black diamond?

The 2.5 ct black marquise is carbonado — black diamond of meteoritic origin, the polycrystalline "ink of the night sky". At 9–9.4 on the Mohs scale it is one of the hardest natural materials you can wear: no special care, wear it every day for the rest of your life.

Wearing & caring for your Ouroboros

The stone needs nothing from you. To keep the silver band and moissanite pavé bright, wipe with the soft cloth included and set the ring aside when using household chemicals or perfume. A gentle patina on silver over years is the metal aging, not damage.

Sizing — an open band that adjusts

The band is an open setting — gently flexible, made to fit most ring sizes without resizing. Made-to-order customization is accepted; please allow 25–45 days of making time.
