The team at AM3 offers no shortage of enthusiasm and ambition as they strive to help an American marble reach its full potential.

Thanks in part to labor laws, environmental laws, and unions, American quarries have gradually become less dangerous workplaces with better pay and benefits. The sense of appreciation and trust among the three managers is palpable, and it’s clear they feel a sense of satisfaction in their efforts to make the job better and safer for everyone.

TexaStone taps into 16 individual quarry pits to produce six different varieties of limestone. A 55,000 square-foot fabrication shop sits on the property, equipped with state-of-the art machinery.

Throughout the evolution of this American limestone company, two things have always been in plentiful supply at Vetter Stone: stone and Vetters. And both are here to stay.

Tucked inside Dorset Mountain is the world’s largest underground marble quarry, spanning an area of about 16 football fields and stretching for over a mile – all underground. There’s one entrance to the Vermont Danby quarry, and it’s the same one that’s been in use for over 100 years.

Colorado Marble is prized for the stone’s pure color, pure composition (99.56% calcium carbonate), light veining, and consistency of the pattern throughout the formation. These attributes and beauty – in addition to the sheer quantity of stone present – give Colorado marble a place of prominence in the world market.

The story of Rocky Mountain Quartzite is a classic American success story that brings together all the necessary elements: favorable geology, a product that could distinguish itself from others, and a business plan and workforce that could develop the company to its full potential.

Every block of stone holds a story. Not just in its geologic past, but also in the ways that stone becomes part of human history. Behind every successful quarry is a collaboration between the forces of nature that created the stone, and human inventiveness that built it into a successful venture.

White stones are popular, frequently mislabeled, and often misunderstood. Learn how to tell if your white stone is a granite, quartzite, or marble. White stones are popular, frequently mislabeled, and often misunderstood.

Learn how to test stone samples for hardness, acid resistance, and porosity. Kitchen designers, architects, fabricators, and restoration professionals can use diagnostic techniques to learn as much as they can about particular varieties of natural stone.

Engineered quartz and natural quartzite are both popular choices for countertops, backsplashes, bathrooms, and more. Here’s a quick and handy reference for understanding where they come from, what they’re made of, and how they differ.

It can be difficult to find reliable information about the practical properties of different types of countertop surfaces. In a quest to bring more data-driven information to the countertop industry, this article offers side-by-side performance testing of four categories of materials.

Minerals are the components of all natural stones. The color of every natural stone, whether it’s jet black, glittery silver, or a kaleidoscope of Technicolor – comes from the individual minerals. Read more in this handy guide to the ingredients of your favorite natural stone.

Many people are curious about the differences between natural stone and manufactured surfaces, and my approach is always the same: be wary of marketing claims, learn as much as you can, understand the properties, and be informed.

Is quartz natural stone? Our geologist analyzed samples from several different quartz manufacturers. Sort fact from fiction using real scientific data to prove performance statistics.

By experimenting on stone samples, you’ll not only gather key bits of information, but you’ll also gain confidence in the real-world attributes of various stones.

Bookmatched slabs sometimes look like butterflies, or Rorschach (inkblot) tests, or many other fanciful shapes. Bar none, bookmatched slabs are one of the most dramatic and impressive ways to use natural stone.

A bit of geology can shed light on why or where we’d want to use a given stone. Geology also helps us appreciate that every slab of stone offers a little glimpse into deep time and the dramatic forces that shape the planet.

Once you’ve come to terms with soapstone’s softness, you can revel in its strengths. Soapstone is remarkably resistant to staining or damage from acids. The density of the stone makes it practically impervious.

Quartzite picks up where sandstone leaves off. It’s a metamorphic rock – one that’s been baked into an extra-tough stone by the heat and pressure that only comes from deep burial way down in Earth’s crust.
