Onyx Stone

Generally, in the decoration and construction industry, the term "Onyx stone" usually refers to a type of calcite-based stone with beautiful, layered bands (Banded Calcite). This type of Onyx is classified in the same group as Travertine and Marble, rather than the "True Onyx" known in geology. True Onyx is a quartz mineral in the chalcedony group, which is often used for jewelry.

The Onyx stone used in decorative work has a key distinctive feature: translucency. This allows light to pass through the stone, creating a unique and striking beauty when used with backlighting. Additionally, it boasts a wide variety of patterns and colors, ranging from white, cream, honey-yellow, green, pink, and red to brown. This diversity allows it to be selected to match different design styles.

Onyx stone can be categorized by its colors and patterns, often named after its prominent visual characteristics, such as:

• White Onyx: Features a white or light cream background, possibly with veins of gold, gray, or beige. It evokes a sense of cleanliness, brightness, and luxury.
• Honey/Yellow Onyx: This is a very popular color, with golden-yellow tones similar to honey. It often has white or light brown veins, creating a warm and luxurious feel.
• Green Onyx: Comes in various shades of green, from light green and emerald green to dark green. It may have white, brown, or red veins, offering a fresh, natural, and unique look.
• Pink/Red Onyx: Features tones ranging from light pink to deep red. The patterns are often complex and strikingly beautiful.
• Brown Onyx: Presents in various shades of brown, often with contrasting cream or white veins, giving a sense of calmness and classic style.
• Black Onyx: Translucent, solid black onyx in large slabs for decoration is very rare. Mostly, it refers to dark-colored stones with white or other colored veins, or it may refer to true Silicate Onyx, which is more commonly used in jewelry.

• Outstanding Beauty: Its patterns and colors are unique, with no two slabs being the same, creating a luxurious and interesting look for any space.
• Translucency: It can be installed with backlighting to create a stunning focal point at night or in low-light areas. This makes it ideal for bar counters, decorative walls, or reception areas.
• Atmosphere Creation: The colors and patterns of the stone help create different atmospheres. For example, light colors provide a bright and airy feeling, while dark colors offer a sense of luxury and calmness.
• Versatile Applications: It is suitable for interior decoration such as countertops (especially in areas not frequently subjected to impact or harsh chemicals, like bar counters or coffee tables), feature walls, bathroom wall cladding (in dry areas), flooring (in low-traffic areas), washbasins, lamps, and other decorative items.

• Purpose of Use: First, determine the installation area to select the appropriate thickness and size. Consider whether you require translucent properties for backlighting.
• Choose Color and Pattern: Consider colors and patterns that match your overall design style. It's advisable to view the actual stone slabs at a stone yard, as each slab has a unique pattern. If you desire a continuous pattern (bookmatch), you must select slabs cut from the same block and arranged sequentially.
• Inspect Quality: Check for consistency in color and pattern. Inspect for cracks, chips, or other defects that may have occurred during production or transportation. Inquire about any surface repairs (if applicable).
• Consider Translucency: If you plan to install lighting behind the stone, you should test the light transmission with a sample slab or ask to see photos of actual installations.
• Select a Reliable Supplier: Purchase from a store or company with expertise, the ability to provide good advice, and reliable after-sales service.
• Budget: Onyx stone is more expensive than other types of natural stone, such as granite or common marble. You should set an appropriate budget.

Installation

• Requires Skilled Technicians: Onyx is more fragile than granite. Cutting and installation require caution and appropriate tools. It is advisable to use technicians with specific experience in installing onyx.
• Support Structure: The installation surface must be prepared to be strong, smooth, and level.
• Cement Adhesive: White or transparent cement adhesive should be used to prevent the adhesive's color from affecting the color or translucency of the stone.
• Backlighting Installation: The placement of LED light panels or other light sources and wiring must be planned and completed before installing the stone slabs.

Maintenance

• Sealing: Onyx is porous and absorbs water easily. A sealant for natural stone should be applied immediately after installation and reapplied periodically as recommended by the sealant manufacturer to prevent stains and blemishes.
• Cleaning: Use a soft cloth dampened with clean water or a pH-neutral natural stone cleaner. Avoid acidic (e.g., vinegar, lemon juice) or highly alkaline cleaners and abrasive powders, as they can damage the stone surface.
• Prevent Scratches: Onyx is less hard than granite. Avoid dragging hard objects across the surface. Always use coasters, cutting boards, or trivets.
• Beware of Stubborn Stains: Wipe up spills or dirt immediately, especially liquids that are colored or acidic (e.g., wine, coffee, soft drinks), to prevent stubborn stains and surface etching.
• Polishing: If the surface becomes dull or has minor scratches, a professional can be hired to repolish the surface.

Proper care will help maintain the beauty and prolong the lifespan of onyx, making it a worthwhile investment for the luxury and uniqueness of your space.
