I found a large stone of aventurine from Wyoming at a rock shop in Estes Park, Colorado. The semi-precious stone aventurine is used mostly by jewlers to make ear rings and other jewlrey.  My cousin cut it into slabs for me so I could put it in a table.

This 24" square x 18" tall table is available on my web site with free shipping to the 48 contigous states.

I also have several more slabs available to put on a table top for you.   contact me at Bill@WKPAccentTables.com
