SPECIFICATIONS
Low Absorption Rate and High Flexural Strength
STRENGTH AS WELL AS BEAUTY
Vermont Verde Antique®, while having the “look” of marble is actually a “serpentine” and classified as a hydrous magnesium silicate. With the hardness and durability of most granite, a low absorption rate and high flexural strength, Verde is an excellent choice for both interior and exterior uses.
TECHNICAL INFORMATION
Serpentine is a major rock forming mineral and is found as a constituent in many metamorphic and weathered igneous rocks. Serpentine’s structure is composed of layers of silicate tetrahedrons linked into sheets; this structure is what gives VT Verde Antique® its high flexural strength rating.

The Geology of VVA Serpentine
Vermont Verde Antique® is the commercial name for the marble-like serpentine derived from highly sheared ultramafic rocks that have been rewelded and metasomatized by the process of serpentinization. These ultramafic bodies are now recognized as segments of ancient oceanic crust that became part of the eastern North American continent during the Taconian orogeny. This is considered to be middle Ordovician in age, around 450 million years ago.
More deformation and metamorphism took place during the Acadian orogeny around 360 million years ago. This may have resulted in the polishable Vermont Verde Antique® serpentine.
LEED CERTIFICATION
Utilizing Vermont Verde Antique® on your project can help gain credits toward Commercial LEED certification in several categories.
Have you used Vermont Verde Antique® to help you achieve your desired LEED certification? Contact us if you are interested in sharing your project story with others on this website.
Under Energy and Atmosphere, Vermont Verde Antique® could positively impact the energy efficiency of a building with its high thermal mass helping to regulate temperature changes.
In the Materials and Resources category, Vermont Verde Antique’s® quarry generates almost no waste rock; from the largest block to the smallest piece, everything is now used. We are in fact now utilizing some of the older historic “waste” piles in present projects. Another possibility is that as the building’s life cycle is completed the durability of Vermont Verde Antique® will allow for its reuse on other projects.
Our quarry and processing plant are ideally located for projects being completed in the Northeast. Our 500 mile local radius covers all of New England and extends to US cities such as New York, Philadelphia, Washington, Pittsburgh and Cleveland, as well as Canadian cities including Toronto, Montreal, Ottawa, Quebec and Halifax.
In the Innovation and Design category, Vermont Verde Antique® could contribute to the performance of the building by helping to reduce life cycle costs in such areas as durability, mold resistance and improved air quality.
We operate both our serpentine quarry and processing facilities in an environmentally sensitive manner and take pride in our place and commitment to the communities where we live and work.

Vermont Verde Serpentine has been a favorite of domestic and international architects, designers and fabricators for over a century.
We recently had a visit from Michael K. Chen and his team from MKCA of NYC to view the 34 book-matched slabs of Verde that will make up a stone spandrel that is going to surround a showpiece residence they are building in Katonah, NY.
