Request for Donations - Silent Auction

Conference hosts CGA, AGA and VCC invite you to donate items to the annual Gem Conference Auction. Needless to say, for a good auction interesting objects are needed. Let’s make this year's auction the best yet, and the most fun. Not only is it a chance to get that specimen you have been hunting for, it's a way to raise funds to help cover costs of the conference and raise funds for student scholarships. So dig into those old boxes in the garage, clear out the cupboards, drawers and shelves. Who knows what you might find to donate!

This year, through the VCC Foundation, donations between $50 and $1000 will receive a tax receipt when accompanied by documentation which indicates the fair market value of the item (for example, a purchase receipt or an appraisal)!  Those items over $1000 require a third party appraisal (government rules). All donations are greatly appreciated. We will have the appraisals done, if required.  Please note that donations of “services” are not eligible for tax receipts.

Please download the donation form and help us out!

Short Courses

This year's gem conference offers an incredible opportunity to upgrade skills by attending specialized workshops offered by leading experts in the field. Make sure you allow time before and after the conference for these special events.

Geology of Gem Deposits
Friday, October 16, 2015; 0900 - 1600 hrs

This seminar will be presented by three outstanding world-renowned gemstone geologists.

Gem deposits are rare because, in general, the conditions that promote their formation are unusual and thus worthy of scientific study. Recently, modern geological and analytical techniques have been applied to gem occurrences worldwide, and our models and understanding of their formation are being radically altered.

This one-day short course looks at gemstones from a geological perspective and reviews our current understanding of the big deposits - diamond, ruby, sapphire, emerald - and will briefly look at some of the lesser-known coloured gems.

Space is very limited. Registration will be on a first-come, first-served basis.

$300 for conference delegates
$350 for all others

Registration Deadline:  October 9, 2015

Jade (Fei Cui) Identification & Valuation Seminar & Workshop
Tuesday, October 20, 2015; 1000 - 1630 hrs

This workshop will be presented by Dr. Edward Liu, Research Geologist & Gemmologist, Gemmological Association of Hong Kong, and scientific committee member of the Er. Edward Gubelin Association.

The seminar & workshop will consist of:

  • introducing some simple & effective methods for hand sample Fei Cui jadeite identification with the main focus on identification of untreated natural, treated, and imitation Fei Cui.
  • classification of Fei Cui varieties
  • Distinguishing between three members of the Fei Cui group
    • jadeite jade
    • omphacite jade
    • kosmochlor jade
  • the valuation of Fei Cui

$300 for conference delegates
$450 for all others

Registration Deadline:  October 9, 2015
Register now, as space is limited, and available on a first-come, first-served basis.
