Description

Onyx is a banded, translucent stone formed from calcite, often found in caves or near limestone deposits. It’s technically a type of travertine or limestone that forms from cold, dripping water rich in calcium carbonate. Onyx is prized for its striking bands, vivid color layers, and ability to transmit light, making it a favorite for decorative and luxury applications.

Often used for backlit panels, countertops, wall cladding, sinks, and feature elements, onyx is considered a luxury material.

Qualities (Pros):

• Visually Stunning: Onyx is one of the most aesthetically dramatic stones, with vivid colors (white, green, amber, honey, pink, red) and distinct veining or banding.
  Translucent Properties: Can be backlit for a glowing, ethereal effect — ideal for feature walls, bars, vanities, and decorative panels.
  Luxurious Appeal: Instantly elevates the look of a space — commonly used in high-end interiors, spas, hotels, or statement pieces.
  Smooth Polish: Can achieve an incredibly high-gloss finish that enhances depth and color.
  Custom Applications: Easy to fabricate into sinks, lighting features, furniture, and vertical installations.

Limitations (Cons):

• Very Soft and Fragile: Onyx is softer and more brittle than granite or marble. It scratches and chips easily, making it unsuitable for heavy-use surfaces like kitchen countertops.
  Highly Porous: Absorbs liquids and stains easily — requires frequent sealing and careful maintenance.
  Acid-Sensitive: Being calcite-based, it is easily etched by acids (lemon juice, vinegar, cleaning products).
  High Maintenance: Needs gentle cleaning, sealing, and protection from scratching, heat, and chemical exposure.
  Expensive: One of the most expensive natural stones due to its rarity, fragility, and installation complexity.
  Installation Challenges: Requires skilled fabrication and handling to avoid cracking or breaking during installation.
  Limited Applications: Best suited for decorative vertical uses (like wall cladding or panels) rather than functional surfaces.
