I got a big rock of adventurine from a Wyoming quarry at a rock shop in Estes Park. I got it cut into slabs at my cousin's rock shop in Golden. Adventurine is a semi-precious stone that is usually used in earings and other jewlery. I think the large slabs are quite nice on this 24" x 24" x 18" tall side/coffee table.
I have a couple of smaller slabs left that I could make into a table top for you, or I could ship you the table seen here for free when you buy it at my on line shop www.wkpaccenttables.com
