I bought a couple of slabs of this polished Lovers' Lane Breccia at the spring Denver gem and mineral show a few weeks ago.   I mounted them on 1/4 black plastic and used a few of my used wine cords for feet.

This will make a nice accent on your table, kitchen counter.

If you have a polished slab you'd like made into a trivet give me a call at Bill@WKPAccentTables.com
