Verde Antique
When you go a little further north to the Lake Champlain area, you find “Vermont verde antique” or serpentine marble, which is a luscious deep dark green. (Note: Generally, the darker the color, the harder the marble and the more resistant to surface scratches and abrasion.)
Veins are formed when the stone cracks under pressure, allowing fissures for other more liquid minerals to lace through. Calcite and quartz are the most common veining minerals found in marble.
The New England states provide a goldmine of metamorphic rocks, and Vermont has an amazing cross section of them, from slate on the western New York border, to granite and marble in the mountains. The marble deposit in Vermont is one of the largest in the world, and dates from the Cambrian and Pre-Cambrian eras.
