This is a gorgeous 3-stone 18k solid gold ring. The design is an interpretation of Balinese work with detailed granulation and ornamentation.
The center stone is a light-green tsavorite from Tanzania. Tsavorite is a rare form of garnet that is known for its unique shades of green and has become quite expensive in recent years (see link below for more information). This piece has wonderful bright green color but it does have some inclusions (veils) beneath the surface.
The accent stones are pastel blue gem silica from Mexico and were selected because they go perfectly with the light green tsavorite.
The ring at its widest point is approx. 5/8” wide (at the front) and the band tapers to approx. ¼” at the back. This is considered a wide-band ring so you might consider sizing based on rings you wear that are comparable.
