One-of-a-Kind Heaven + Earth Ring in 18kt green gold with round ~13.02cttw Dendritic Agate. Dendritic Agates are usually colorless, white, or grey. They feature natural tree-like inclusions of iron or manganese called Dendrites. We searched through 1000s of Agates and selected the most beautiful, organic, and colorful landscapes reminiscent of another era. We hand-carve sculptural vines around each Agate. Size 7 1/8 which can be sized with meticulous care in our New York atelier.
