This Party Rocks!

Happy birthday to renowned Los Angeles area gemologist-appraiser Charles Carmona. Carmona celebrated his birthday on June 29th in true gemstone-worthy style. Celebrants at his lively bash had plenty to nosh on; not the least of which was a geode cake in a nod to his lifelong passion of mineral collecting. The photo shows Carmona holding his realistic geode delicacy while friend and Caltech professor George Rossman calls out the finer points of crystallography.


Carmona’s Guild Lab has been an iconic presence in Los Angeles’ diamond district serving the trade for four decades. In recent years, Carmona has expanded his gemological services to reach an international market with Guild Gem Lab - www.guildgemlab.com - serving Hong Kong, and Shenzhen, China. You can send a (slightly belated) birthday greeting or just say hi to Charles at www.guildlabs.com.
