Pegmatite Avatar: Exotic Natural Rock from Brazil
Avatar, a Dumortierite/Pegmatite. This material is extracted in the northeastern region of Minas Gerais, Brazil. Dumortierite, a rare mineral that gives the rock its bluish hue, combines with Pegmatite, a coarse-grained igneous rock, resulting in a unique and exotic piece.
Characteristics:
- Mineralogical Composition: Dumortierite is the main mineral that provides the bluish tones, while Pegmatite, composed mainly of quartz, feldspar, and mica, offers structure and color variety.
- Appearance: It presents a mix of blue, green, brown, and cream tones, with complex veins and patterns that vary from slab to slab.
- Durability: It is an extremely hard and resistant rock, suitable for applications requiring durability and wear resistance.
Uses:
- Interior Decoration: Ideal for kitchen countertops, islands, floors, and wall cladding due to its aesthetic beauty and durability.
- Decorative Elements: Can be used in tables, panels, and other decorative pieces, providing a touch of sophistication and exclusivity.
Maintenance:
- Regular Cleaning: Use warm water and mild soap, avoiding acidic or abrasive cleaning products that may damage the surface.
- Sealing: Periodic sealing is recommended to protect against stains and facilitate cleaning.
Installation:
- Flat and Stable Surface: Ensure the installation surface is level and can support the weight of the rock.
- Qualified Professionals: Installation should be done by experienced professionals to ensure a perfect finish and avoid damage to the material.
Geological Information:
- Classification: Pegmatite with Dumortierite.
- Geological Origin: Formed from the slow crystallization of magma, allowing the growth of large crystals and the inclusion of rare minerals such as Dumortierite.
- Extraction History: The northeastern region of Minas Gerais is known for its wealth of minerals and ornamental stones, with a long tradition of mining and producing high-quality stones.
The Avatar rock is an excellent choice for those seeking to combine exotic beauty, durability, and exclusivity in decoration and architecture projects.

Its name was inspired by the characters of the film AVATAR due to the similarity between the colors of the stone and its cast.

Type: PEGMATITE / DUMORTIERITE
About
Formed by a combination of minerals that creates a rare composition of varied and vibrant colors, forming unique, natural and random designs that refer to impressionist paintings, making it one of the most beautiful and exclusive ornamental rocks formed by nature.
Composition
Surface Finishings
Polished
It is the “shiny” surface that results in the plate when receiving the complete finish, that is, until the last grain. Depending on its composition, the polished material may have a higher or lower brightness intensity.
Brushed
It is the resultant surface in the sheet when it receives roughing treatment performed by steel brushes or synthetic materials. Different brushing models can be executed, with greater roughness, medium and few.
Soft Leather
It is the resultant surface in the sheet when it receives roughing treatment performed by steel brushes or synthetic materials. Carried out with a brush of low roughness, which gives it a lightly textured look like fabric.
Flamed
It is the resultant surface in the plate when it receives heat treatment (burned with torch specially developed for the function) that takes out small flakes of the same, making the surface slightly irregular producing the impression that it is rustic.
Honed
It is the resultant surface on the sheet when receiving abrasive grinding wheels up to the grain 120. This grain defines the surface finish limit either as anti-slip or even for the application of resin and subsequent polishing.
Leather Finish
It is the resultant surface in the sheet when it receives roughing treatment performed by steel brushes or synthetic materials. Depending on the type of brushes used you can still reproduce in some materials a surface with a design similar to natural leather.
