Sardonyx & Spinel Beads

Sardonyx is a variety of onyx that typically comes in shades of red (the word "sard" means "red"). Our selection of sardonyx beads are normally dark, and mainly display shades of black, dark brown, dark red, and cream. Some look very similar to black onyx or black banded agate. Sardonyx semiprecious beads display beautiful patterns, including bands, stripes and swirls. When possible, we also carry the classic red variety of sardonyx. Red sardonyx is frequently heat-treated to intensify the red. Onyx is believed to help eliminate apathy, stress, and negative thinking. It is also said to sharpen wits, increase concentration, and prevent absentmindedness. Onyx is sometimes worn to help public speaking since it is believed to make the wearer more eloquent.

Spinel forms in a wide variety of colors: black, blue, red, violet, green, brown, pink, white and colorless, and is most famous for its brilliant red variety that closely resembles ruby. Spinel is also one of August's birthstones, sharing this month with peridot and sardonyx. Spinel was named in 1779 by Jean Demeste from the latin "spinella", or little thorn, due to its sharp octahedral crystals. In ancient times, exceptional large spinel crystals were mined in Southeast Asia, frequently becoming the treasured property of kings and emperors. In the United States, Spinel was recently added as an August birthstone, sharing this month with peridot and sardonyx. For this reason, you'll find both our our sardonyx and spinel beads on this page.
