Onyx is a showstopper of a stone. Used for centuries in jewelry, carvings, and for architectural accents, the stone’s stunning swirls and speckles of rich, vibrant color and unusual translucency make it an extremely sought-after material. Rarer than fine marble and highly desirable for its unique appearance, it remains a popular choice for homeowners looking to add a truly special touch to their homes. And also, make everyone else jealous. 

It is mostly made of calcite and is formed in caves in several areas around the world, mostly in the Middle East, North Africa, and South America. When water drips from stalactites and stalagmites and then evaporates, it leaves behind deposits of calcium carbonate and other minerals.  And this causes the stone’s colorful bands, swirls, and spots.


     What makes onyx unique and desirable is how lush and deep the colors are, as well as their wide variations of colors and patterns. Another somewhat unusual property of it is the translucency, meaning that light can penetrate it. When lit for behind or underneath, this creates a soft glow that further highlights the color and pattern variations in the stone, adding dimension to the piece.

     Onyx’s unique characteristics and rarity make it an excellent choice for homeowners who not only want to incorporate natural stone into their homes, but also create a signature, custom accent that most other people simply won’t have due to the stone’s cost and exclusivity. However, it’s very important to know the stone’s limitations. Due to that, it will help you determine how best to incorporate it into your space.
