Onyx offers a very luxurious, classical, posh appearance as its translucence is its greatest and most unique feature. In reality, though it refracts and manipulates light, onyx is really an ancient form of marble, which gives it a one of a kind beauty. There is a reason that Onyx has been used for hundreds and even thousands of years by royalty and the wealthy, as it is a highly coveted, extremely attractive form of marble.

The translucent beauty of this stone is a real head turner.

Onyx is often considered as a mineral gem, and is prone to damage from certain acids such as citric acid and acids found in certain liquors and vinegars. Onyx must be properly cared for and maintained to keep its great, spectral beauty, as onyx is a softer form of marble. With anything as brilliant, beautiful and expensive as onyx, however, a high level of care and appreciation must be expected.

For this reason, Onyx, like softer limestones, can only be used for certain purposes. Bars, islands, decorations like artwork and breathtaking trim work are perfectly suited for onyx, where brilliant light can be refracted from various shiny surroundings, offering a breathtaking and extremely unique and classy decor.

Onyx also offers other suitable uses in the home, including:
  • Vases and other kitchenware such as immaculate bowls
  • Light fixtures and covers
  • Chandeliers
  • Exotic drinking vessels
  • Sinks
  • Bowls.


As stated, though onyx is extremely brilliant and beautiful, it is a somewhat delicate substance and requires great care. When considering utilizing onyx, think about what it will be used for and where it will be used. It must be cared for an maintained, but is best used where its refractive qualities can be backlit or where it can r4eflect light and bright colors in some way, shape or form.

While onyx is extremely precious and unique, it is really best utilized when suited to a purpose that best extends its life and beauty. Decorations such as vases, trim and other purposes highlight the exotic beauty of the décor as well, so if you do choose onyx, keeping certain onyx decorations in mind will further highlight your choice.
