Geoff is an author, gemmologist and musician.
In 2013, he published the popular Handbook of Gemmology, the first digital gemmological reference book, which is now in it's fourth edition and is celebrating it's fifth anniversary with a special two volume printed edition.
He is also the founder and CEO of the World Gem Foundation, a non-profit organization dedicated to the preservation, promotion and study of gemmology through their comprehensive range of theoretical and practical gemmological courses and programs.
Passionate about music, he is one half of AVA MUSICA who are preparing to release their first studio album at the end of May 2018. Recorded at the state of the art Palma Music Studios, the album features twelve original compositions by Geoff and the ethereal vocals of Ava.
