- a deep emerald-to-mint coloration, this premium material bridges the gap between high-end stone architecture and ornamental gem art quarried in Chagai district in Balochistan, Pakistan. Geologically, Pakistani Green Onyx is not a silicate-based true onyx. It is actually a highly crystallized form of banded calcite (travertine) formed over millions of years by rhythmic calcium-rich water deposits. The "Medium Green" classification refers to a well-balanced, rich background that sits perfectly between pale jade and deep forest green. It is heavily characterized by parallel flowing bands of milky white, golden amber, warm cream, and deep rust-red veins. The defining feature of this stone is its crystal-clear mineral structure. When sliced into slabs and paired with a custom LED backlighting system, the stone "awakens," allowing light to pass through and radiantly illuminate its inner veins
Description
Medium Green Onyx from the Chagai district in Balochistan, Pakistan is a luxurious stone characterized by a rich emerald-to-mint green coloration. Geologically, this stone is not true onyx but rather a form of banded calcite (travertine) formed by calcium-rich water deposits over millions of years. Its unique aesthetic features include flowing bands of milky white, golden amber, warm cream, and deep rust-red veins, all enhanced when backlit due to its crystalline structure.
Physical and Mechanical Properties
- Water Absorption: 1.30%
- Density: 2730 kg/m³
- Flexural Strength: 9.05 - 11.0 MPa
- Compressive Strength: 139.32 - 145.00 MPa
- Hardness: Medium (Calcite typically has a Mohs hardness of about 3)
- Porosity: Moderate due to its calcite composition
- Slip Resistance: Relatively low, so it’s more suitable for vertical applications or use in areas where slip risk is low
Chemical and Mineral Compositions (approximate % by weight)
- Calcium Carbonate (CaCO₃): Approximately 92-95%
- Others: Small amounts of iron oxides and trace minerals that contribute to its color variations
Usage
- Interior Decoration: Ideal for wall claddings, backsplashes, and columns
- Countertops: Used in kitchens and bathrooms for a luxurious finish, though care must be taken due to its moderate hardness
- Ornamental Pieces: Suitable for crafting decorative items like vases and figurines
- Backlit Installations: Perfect for spaces where its translucency can be showcased with LED backlighting
Maintenance
- Cleaning: Use a soft cloth with mild soap and water. Avoid acidic or abrasive cleaners to maintain its polish
- Sealing: Regular sealing is recommended to protect against stain absorption due to its porosity
- Avoidance of Excessive Force: Being a softer stone, it is prone to scratches and should be treated with care
Cutting Sizes and Surface Finish Options
- Cutting Sizes: Typically available in custom slab sizes, but common dimensions include 60x60 cm and 120x60 cm
- Surface Finish Options:
- Polished: Most common for a glossy and reflective surface that enhances color depth
- Honed: Offers a matte finish for a more subdued appearance
- Leathered: Provides a textured finish that adds to tactile interest while slightly reducing the visibility of scratches
Medium Green Onyx serves as an embodiment of both architectural elegance and artistic natural beauty. Its unique visual attributes, along with its distinct translucency, make it an exquisite choice for those seeking a statement piece in both residential and commercial environments.
