Green Sapphire

Green Sapphire is also corundum (aluminum oxide), the same family as blue sapphire and ruby.

Its unexpected green comes from trace iron within its structure.

Under magnification, it often shows fine, alternating blue and yellow zones that read to the eye as green.

It forms in igneous and metamorphic rocks under high pressures and temperatures; Australian and Thai varieties, richer in iron, show deeper greens.

Less known than its blue cousin yet just as precious, green sapphire has long been a collector’s stone.

In the 19th century it was sometimes sold under the misleading name “oriental emerald”—though it has nothing to do with emerald; today it’s prized precisely for the authenticity of its natural, serene tone.

An underrated gem, perfect for anyone seeking something unusual, durable, and elegant.

Shades range from a delicate mint green to a deep, slightly teal green. The richest colors come from Australia, Thailand, Tanzania, and Montana.

Sapphire symbolizes loyalty and wisdom, and the green variety adds a note of calm and balance. Corundum is the birthstone for September.

With a hardness of 9, it’s extremely durable and ideal for everyday-wear jewelry, needing only protection from major impacts.

It cleans easily with a soft cloth. This elegant tone is beautifully showcased in 925 sterling silver and yellow gold.
