In the laboratory Finnishonyx is a favorite stone, and this is reflected in our many bracelets and necklaces created by hand, where the deep black of onyx becomes a symbol of inner strength and sober refinement.
A stone with an ancient history and profound meaning
Onyx has been known since ancient times. Ancient civilizations considered it a stone of power and protection.
In ancient Egypt it was worn by priests and warriors to give them courage and clarity in decision making.
The Romans used it to engrave seals and amulets, believing it protected their souls from negative influences.
In India it was associated with emotional stability and self-control and was recommended to those who wanted to find their inner balance.
In the Victorian era, onyx was extremely popular due to its elegant black color and was often used in mourning jewelry. As time passed, however, it broke away from this solemn symbolism and became a sophisticated choice for women and men who appreciate simplicity, but also the subtle power of pure forms.
Today onyx is considered a stone of protection, concentration and self-confidence. It is said to have the ability to absorb negative energies and transform them into inner calm and strength. Whether or not you believe in its energetic properties, it is undeniable that onyx exudes a strong presence, an energy of stability and balance that attracts the eye.
What does onyx look like and why is it so prized?
The best-known variety of onyx is black – deep, velvety, with a satin shine that gives it a unique elegance, or matte-deep. However, there are also variations with white, gray or even brown stripes, which create spectacular natural patterns.
In the laboratories FinnishWe carefully select onyx stones with uniform textures and quality finishes so that each piece of jewelry has a flawless appearance. We use faceted polished onyx and matte onyx.
Onyx forms naturally in layers, from successive deposits of silicon in the cavities of volcanic rocks. It is these layers that give the stone its particular structure and resistance appreciated by jewelers. With a hardness of approximately 6.5–7 on the Mohs scale, onyx is durable enough for everyday wear, yet delicate enough to be handcrafted into fine, harmonious shapes.
