Sardonyx Gemstone Properties

Design Possibilities

Delicious, that's how one person describes sardonyx's colors. Sardonyx is actually agate whose banding is straight and parallel. Like much agate, it is dyed to enhance or change its colors. Dyeing agate was an art practiced by the Romans from early on, but it reached perfection in the 1820s in Oberstein, Germany. That town is still the world's center for the finest cutting and dyeing of agate. Although the details of the process remain a commercial secret, we do know that iron oxide is a pigment used to create the rich combination of deep orange-reds in red and white bull's eye sardonyx and in the red and white-banded variety. Carbon is used to create the striking deep black banding in black and white banded sardonyx. The effects are stunning: ancient agate beads in rich colors perfect for blending with solid colored red or black beads.

Metaphysical/Healing Properties

The spiritual values of red and white-banded and red bull's eye sardonyx make these stones particularly powerful. In fact, they allow one to project such an incredible charisma, those "in the know" suggest they should be used with care so we don't overwhelm others. Wear them, they say, when you want extra power in a particular circumstance. A teacher friend of mine wears red bull's eye sardonyx when she is working with a particularly difficult group of students.

Much of black and white-banded sardonyx's power comes from its association with a particular body type--slender, quick-moving people who are intellectually active. If you're clever, versatile, highly verbal and have an optimistic disposition, those traits may be heightened when you wear black and white-banded sardonyx. Or you can wear it to help you control one of those traits if it's working against you.
