Last Updated: 9th Apr 2016

By Jolyon & Katya Ralph

This is a LIVE report, keep this page loaded for live updates - new images will appear as they are added.

Today I'm in San Diego st a special Symposium to honour the life of Roger Merk, who was involved in the organization of the Sinkankas symposium for many years.

Reprint of article from The Pegmatite, bulletin of the San Diego Mineral & Gem Society

The first symposium in 2003 was about Quartz.

Robert Weldon & Bill Larson

Myricke - Quartz with cinnabar inclusions. Sinkankas hated names such as 'myrickite' where someone names a lapidary material after themselves.
