I am a lapidary artist and I live in Portland, Oregon. I have an extensive knowledge of semi-precious gemstones from all around the world. I have been cutting, polishing, and studying gems and minerals extensively since 1974 and I have been a full time lapidary since 1990. This has given me, shall we say, an encyclopedic understanding of a unique area in earth science. Since 2000 I have been creating a photographic record of all sorts of gemstones and minerals that can be very helpful in identifying unusual stones.
