County Museum of Natural History and the Gemological Institute of America (GIA) on their trips to the Colombian emerald source.^[3]

He was a speaker at the GIA's International Gemological Symposium in 1991.^[3] In 2006, he presented at the GIA Gemological Research Conference in San Diego, California on the topic of "Subjectivity in Gemology".^[4] Ringsrud has sat on the board of directors of the American Gem Trade Association (AGTA).^[5]

He is also involved in charitable activities in Colombia aiming to assist people in the mining area.^[6]

Emeralds, A Passionate Guide is a 2009 non-fiction work published by Ringsrud's Green View Press,^[1] billed as an "adventure into the unique world of emeralds".^[1] In addition to the textual combination of anecdotes and scientific facts, this guide contains 70 microphotos and over 250 color photos and illustrations.^[1][7] The book includes a foreword written by John Koivula, the Chief Gemologist at the GIA.

Screenwriter Diane Lake described Emeralds, A Passionate Guide as "a book [that] glistens and gleams—that fairly sparkles with its intensity".^[8] The reviewer for pricescope.com stated that: "The subtitle of Ronald Ringsrud's new book A Passionate Guide, The Emeralds, The People, Their Secrets has been well selected. The book is not just about an emerald, more specifically a Colombian emerald; it is about a country, its people and one man's love affair with it all".^[9] The book has received other positive reviews.^{[10][11][12][13][14][15]}
