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
