    Ed Swoboda Specimens Uploaded & New Sales Prices
    We have been busy over the last several months refining our website, and uploading over one hundred specimens, many of which I had stashed away 15 to 30 years ago for my personal collection. In January we also began uploading specimens I purchased in 1994 from Ed Swoboda. These were pieces he had put back in the 1960s and 1970s, and are all very good examples, many from localities I have never seen on the market. We have also reduced prices on about 30 percent of the specimens on our website to try and keep things moving.

    If you see something you like, don't hesitate to ask for terms and pricing. And, if there is something you are looking for, send us a note. We have over a thousand more specimens waiting to be photographed and uploaded.

    New Website Launched
    We are pleased to finally announce that our new website was brought on-line today. Among other features, the new site provides extensive search capabilities, ease of inquiring about specimens, and has a full featured Shopping Cart to make ordering simple. This upgrade also affects our GneissWare site, and it now offers integrated ordering into the new Shopping Cart. After a long wait, we are finally starting to add new specimens to the site. Some have been in storage for decades, so we hope you'll find them interesting. We will continue preparing and photographing new specimens, and posting them to the site. Check it out soon.

    Let us know what you think of the new Bob Griffis Minerals website. We'd like to hear from you.
