Madagascar is the producer country that produces the most jewelry-quality sapphires in the world. Depending on the sources and the periods, Sapphires from this provenance represent between 20 and 70% of the world market.
Sapphire from Auvergne
France is also a country that has deposits of blue sapphire. We collect alluvial sapphires in Auvergne using the so-called beat method. Although relatively very small, some may be found that can exceed one centimeter and have a beautiful shade of blue. The exploitation is purely artisanal and represents very low volumes, the Sapphire from Auvergne is therefore not widespread on the market. The stones are generally midnight blue and turn green.

Sapphire is a transparent stone in its finest quality, benefiting from superb clarity and brilliance. Extremely varied colors, representing all the colors of the chromatic spectrum except the red color which characterizes ruby, another variety of corundum. It is a pleochroic gem (which has different colors depending on the angle of observation). It will present itself in its most beautiful aspects in daylight or under fluorescent light. Conversely under white light, its color will be much less attractive. The most popular stones will be stones with little or no inclusions with the naked eye or even with a magnifying glass at x10 magnification and with a beautiful color, with a lot of shine. Stones with a milky or silky appearance will be much less popular and sought after.

The industrial synthesis methods reproduce in the laboratory the natural conditions of formation of sapphires whose chemical composition and physical properties are the same as those of natural stones. These methods have made it possible to create synthetic corundum or so-called Verneuil synthesis which are synthetic Sapphires notably intended for the industrial production of watch glasses, smartphone screens, camera lenses, due to their very high resistance to shocks and scratches.
