Organics

Yes, this is a hot topic!  Organic gems are always misunderstood and puzzling.  Now with an increased pressure on illegal animal trade, it is a good time to brush up.  Fossil Ivory is now being regulated alongside modern Elephant Ivory.  We will help you see why.  Examine samples of ivory, bone, tusk, coral, fossils and probably a pearl or two for balance.  Come and explore and challenge your previous knowledge.

Separating Similar-Looking Stones
Eric Fritz, Gem-A

How often do you glance at a stone or piece of jewelry and say “oh yeah, that is a so and so… “?  As gemologists, we all “sight ID” from time to time!  What if you have several stones similar in appearance sitting in front of you?  Can you still separate them out visually?  We will explore several groups of similar looking stones and see what hand-held tools can help us separate them out.  Always a fun exercise with lasting results!
