AGA Seeking Sponsorships

As part of our continuing efforts to provide the gemological community with cutting edge speakers and topics, and to continue and expand our focus on current gemological issues and related research projects, we are introducing a new initiative: seeking sponsorships for upcoming AGA conferences.

We are trying to identify potential sponsors that align closely with our mission and whose product or service would be of benefit to our membership, whether directly related to the jewelry/gemological world or other pertinent service such as banking, insurance, equipment, etc.

We all have our own connections and contacts within the corporate community. We would appreciate any suggestions for potentially interested parties or companies, and the contact information for them. Please know that any suggestions or contact information will be closely guarded and will be used solely by the committee to solicit sponsorship.

We are also asking for the participation of a few motivated AGA members to serve on the Sponsorship Committee.
