Stone Information

Product Name: Acara Ruby Quartzite

Supplier: Gramil Granitos e Mármores

Color & Appearance:
Acara Ruby Quartzite features a predominantly creamy-white to light beige base color, adorned with striking, irregular veins and patches of rich reddish-brown to rust-colored markings, reminiscent of ruby-like hues, giving the stone its name. The natural patterning is bold and organic, with the contrast between the light background and deeper red accents creating a dynamic, luxurious visual effect. This exotic quartzite is ideal for high-end residential and commercial applications where both elegance and uniqueness are desired.

The stone exhibits a fine to medium-grained crystalline texture, with a dense, interlocking structure typical of high-quality quartzite. Polished surfaces highlight its vibrant, organic patterns, while honed and leathered finishes enhance tactile appeal. The compact crystalline matrix ensures excellent strength, dimensional stability, and durability, making it suitable for both interior and exterior applications.
