THE EMERALD: TREATMENT, DETECTION, EVALUATION

> By Pierre-Yves Chatagnier & David Goubert, gemstone dealers
> Language: French
> Schedule: Thursday at 11 AM
Mineral & Gem 2016 Conférence Émeraude> Duration: 1 hour

Emerald is one of the rarest gems in the world, and the demand in the jewelry sector remains strong. World production is provided by a handful of countries such as Colombia, Zambia and Afghanistan. Only a very small percentage of emeralds will be of sufficient quality for use in jewelry, without treatment. Improving the purity of emeralds by filling with oils or resins has become an unavoidable step today. The objectives are the beautification of the emeralds that consists of reducing the visual impact of microcracks, increasing business value and making mining profitable. The lecture will focus on the different types of treatment used, the detection techniques and the quantification of beautification.

ORIGIN OF THE DIVERSITY OF THE ALSATIAN VINEYARD AND TERROIR

> By Stéphanie Colicchio, geologist and environment leader at the Maison de la Géologie in Sentheim
VisuelConférence2> Language : French
> Schedule : Thursday at 1.30 PM (also Saturday at 3 PM)
Duration: 1 hour

The Alsatian landscape and its vineyards are the result of a long and turbulent geological history that stretches over several hundred million years.
To understand the specificity of the Alsatian vineyard, which lays on a mosaic of soils and the diversity of terroirs that results from that, we will visit the geological time. This conference will present the features of the Alsatian vineyards, its cultivated vine types  and the variety of soils encountered.
What are the factors that influence the quality, the personality and the uniqueness of the produced wines? How to link soil, grape variety, flavors and taste sensations of the produced wine? This lecture based on the work of Dr. Claude Sittler, professor emeritus of geology at the University of Strasbourg will bring elements of answers to these questions.


LogoWINES & GEM STONES: AN ANCESTRAL LINK

> By Gian Carlo Parodi, mineralogist and lecturer at the au National Museum of Natural History in Paris
Illustration_Conf_Parodi> Language: French
> Schedule: Thursday at 3 PM
> Duration: 1 hour

This lecture will introduce you to the many links that exist between wine and gemstones. In Greek mythology, this relationship is to be discovered with the legend of the origin of Amethyst, born from the anger of the God of wine, Bacchus, who was in love with a young nymph. At a scientific level, the color of wine is related to the pigment composition of the grapes. Indeed, winemaking, terroir and time are major components that play a role in the color of the wine. Finally, we can find this link as soon as one compares the finest gem collections around the world with the great appellations of Burgundy wines.

Illustration_Conférence_Tourmaline_TourmalineduBrésilCOLOUR ZONES AND GROWTH PHENOMENA IN TOURMALINE CRYSTALS

> By Paul Rustemeyer, Doctor in chemistry 
> Language: French
> Schedule: Friday at 11 AM
Duration: 1 hour

During their growth, tourmaline crystals react to changes in their environment by getting new colors and shapes. The history of their growth is kept within this mineral as in a data logger whose data materialize by different areas of color, often difficult to perceive. Only by cutting the crystal into slices can these very aesthetic structures clearly be recognized and studied.
Many striking photographs will present seven different origins of the colors of tourmaline. The book “Tourmaline – fascinating crystals with fantastic inner world” was born from research of over 1,000 tourmaline crystals.

JADE, THIS BEAUTIFUL UNKNOWN 

> By Caroline Tran-Vinh, gemologist
> Language: French
> Schedule: Saturday at 11 AM
Illustration_Conférence_Jade> Duration: 1 hour

Jade is probably one of the most underrated gemstones and the most imitated in the world. Everyone knows the word ‘jade’ but few people know how to define and differentiate it from its imitations. The term ‘jade’ actually covers two different gemstones, jadeite and nephrite, which makes the study of this complex stone even more complex.
From the bottom of Myanmar to the rivers of New Zealand, through Guatemala or Canada, a brief overview of the fascinating world of jade, offers you  to learn it’s more essential basis to better understand this gem stone that remains for certain civilizations, more precious than gold.


THE FRENCH CROWN JEWELS

> By Éloïse Gaillou, assistant curator at the MINES ParisTech, Mineralogy Museum
> Language: French
> Schedule: Saturday at 1.30 PM
> Duration: 1 hour

Founded in 1530 under François 1st, the collection of crown jewels of France was intended to gather a real inheritance for the Kingdom of France, developed and passed from king to king.

GaillouIt was under Louis XIV that the Royal collection reached its peak, with mythical acquisitions such as the great Blue Diamond of France, the Grand Sapphire or the Regent diamond.
The history of the collection is full of ups and downs, and it is in 1887 that the greatest tragedy of the collection occurred when the French government decided to sell the Jewels, more to get rid of the royal emblem than to replenish state coffers. Cut stones, beads and jewelry were scattered around the world during a major auction, mostly purchased by large jewelers. On the advice of experts who evaluated the collection, it was decided to preserve some of the stones according to artistic or scientific interest, in three major French institutions: the École des Mines de Paris, The National Natural History Museum and the Louvre. These treasures are still to be seen, in these museums,  and all over the world mainly in private collections. They sometimes even reappear on the market. This presentation will also allow you to discover these places where you can still see the old national treasure exhibited.

METEORITES AND THEIR IMPACTS

> By Alain Carion, speaker 
Illustration_Conférence_Météorites> Language: French
> Schedule: Sunday at 11 AM
> Duration: 1 hour

The Gauls’only fear was that the sky will fall on their heads. But in fact, only a dog and a cow were killed by the fall of a meteorite.
In order to know everything or almost everything about these famous ‘space stones’, the speaker addresses the fundamental aspects of the meteorites and their impacts: origins, ages, varieties and classifications.
Alain Carion will discuss the formation of the moon and the solar system, the origin of the oceans and even the origin of life, brought from space by meteorites. Studies of these space rocks are the basis of major scientific progress.
Focus on the oldest preserved meteorite of Ensisheim in Europe and on the Rochechouart crater near Limoges, an impact of 20 km in diameter and formed there over 200 million years.


MINERALOGY AT THE MUSÉE DES CONFLUENCES

> By François Vigouroux, aassistant for management and conservation of museum collections at the  Musée des Confluences (science centre and anthropology museum) 
Musée des Confluences Lyon France> Language: French
> Schedule: Sunday at 1.30 PM
> Duration: 1 hour

Inaugurated in December 2014, The Confluence Museum has surpassed the millionth visitor within  one year of opening.
What then is the place of mineralogy among the two million items kept inside the museum. Inheritance  of the collections of the Museum of Lyon founded in 1772, which was itself initiated from the merger of several cabinets of curiosities, the Museum has continued to enrich its mineralogy collection. Currently more than 10,000 pieces are preserved there, including valuable collections of azurite from Chessy and colorful fluorite bequeathed by the mining engineer Alexis Chermette.
These collections stand ready to show us their wealth is their secrets.


WINE, A STORY OF STONES?  

Illustration_Conférence> By Marie-Sophie de Maissin, gemologist, expertise and consultancy

Originally from Bordeaux, Marie-Sophie de Maissin will develop our awareness  through this lecture  on the close link between the Bordeaux wines and minerals. To be understood by everyone, this approach will be replaced in daily life. Wines, a story of stones? Or stones, a story of wine? Through this procedure you will get elements of answers.
