Ophiuchi Tanzanite Ring

Sold Out

Renaissance Collection

At its centre, a grey tanzanite reveals shifting tones of lavender, blue, and muted crimson across an ashen base.

Above the finger, a domed structure in palladium white gold rests on a gold bridge formed by three arches. The relationship between dome and bridge allows the ring to read as a constructed object.

Across the dome, an asymmetrical constellation of inverted diamonds animates the surface.
