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.

Price:
$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

Price:
$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.

Corundum Treatments and Pricing Workshop (full day)
Thursday, November 13, 9:00 am -4:00 pm; CGA Member $420/Non-Member $450

This class is an intensive one-day workshop on corundum treatments and pricing. Heating and other methods used to enhance the appearance of corundum are having a profound effect on the market. The sale of treated corundum has dramatically increased the supply of products sold as ruby and sapphire. Accurately pricing corundum requires the professional gemmologist to distinguish not only between treated and natural, but also between the various treatments encountered in today's global market.

This workshop is designed to reconcile the pricing of rubies and sapphires by specific treatment type. 

Participants will examine a variety of natural and treated ruby and sapphire, followed by a presentation concerning pricing considerations. This hands-on session is supported by a PowerPoint presentation featuring high quality images of characteristic features that reveal whether stones have been enhanced, and how.

Pearls
Friday, November 14, 9:00 am - 1:00 pm; CGA Member $220/Non-Member $250

Cultured pearls are one of the fastest growing sectors in the gem trade. Many varieties of Chinese freshwater pearls have earned widespread consumer acceptance across the global market. However, visual similarity of these pearls to the once dominant seawater varieties like Akoya and South Sea pearls has created some challenges for buyers, sellers and appraisal professionals whose responsibility it is to accurately grade and price pearl products for their clients.

Today, cultured pearls are produced in an array of colours, shapes and sizes, yet the standard remains the round to near round white products. Although visually similar, beyond appearance these products share little in common. Market availability, surface quality, and of course price, differ greatly from variety to variety, as well as among pearls of the same variety. Accurately pricing cultured pearls requires the professional gemmologist to distinguish not only between types, but also to correctly assess quality and shape factors within the same variety.

In this workshop, participants will examine and grade a variety of cultured pearls, followed by a presentation concerning common enhancements and pricing considerations. The hands-on session is supported by a PowerPoint presentation featuring high quality images of certain characteristics useful for assessing overall grade.

Emerald Treatments and Pricing
Thursday, April 3, 2:00 pm - 5:30 pm; CGA Member $250/Non-Member $280

This is a half-day hands-on class working with treated and natural emerald specimens, including pricing information.

Participants will examine emeralds treated by various methods and learn the practical techniques used in the field to recognize them. The degree to which an emerald has been enhanced is one of the major considerations when accurately pricing these popular gems. Tips regarding how to estimate the treatment level are also presented.

Value factors such as colour, clarity and transparency are discussed based on the GemGuide pricing system. Emerald specimens have been specifically treated for this program to illustrate the common treatment types and levels of enhancement encountered in the market.
