Sardonyx tumbled stone

❗️ I intuitively select each piece when you purchase one or more

Sardonyx is a striking mineral known for its bold bands of reddish-brown, orange, and white. Its layered look comes from alternating bands of Sard (a reddish variety of Chalcedony) and Onyx, giving each piece a beautifully striped, natural design.

This stone forms over millions of years as silica-rich solutions slowly deposit layers of minerals in cavities within rock. The result is a finely banded stone with a smooth, glossy surface and unique color variations that make every piece one of a kind.

Sardonyx has been admired since ancient times for its beauty and durability—used in carvings, cameos, and decorative objects throughout history. Today, it’s a favorite among collectors who appreciate stones with strong patterns and timeless appeal.

If you're drawn to minerals with character, contrast, and a rich backstory, Sardonyx is a standout choice.
