“Blinded by the Light: Optical Phenomena in Gemstones”

David Horste is a lapidary artist living in Portland, OR. He began making jewelry since he was 12. He designs focal beads using unusual gemstones as well as found objects. David is a returning speaker. The title of his talk will be “Blinded by the Light: Optical Phenomena in Gemstones”.

David will cover the wide variety of optical phenomena that makes some gemstones jump out at us in flashy, glittery, lustrous, shimmering and mysterious ways. He will have many physical samples,  of gemstones that exhibit this optical phenomenon, available for examination as well as purchase.
