THIS IS A NATURAL, UNTREATED, RARE ALEXANDRITE SPECIMEN 

 

MINERAL CLASS = Chrysoberyl, Alexandrite Variety

CHEMICAL FORMULA = BeAl2O4

 

An important validating  characteristic distinguishing a true alexandrite is the crystal's UNMISTAKABLE   BLUE/GREEN   color under florescent hot light (5,000-6,500 K) changing to a  RASPBERRY RED  under incandescent cool light (2,700-3,300 K).

 

For photographic purposes the  RASPBERRY RED  color change is made with strong cool back lighting.

 

 

HOW WE ARRIVE AT OUR PRICING

Alexandrite is a rare and exclusive mineral therefore the offerings are sparse.  Nevertheless we try to keep our prices reasonable and accessible to our customers. The diverse attributes of crystal formation, size, intensities of color change and lusters are the main factors affecting the price that each piece is being offered. 

 

Along with diamonds, rubies, and emeralds, top quality alexandrites are among the most expensive gemstones in the world

 

The rough alexandrites we sell are commercial collector’s grade. Our samples are transparent to translucent on the edges and translucent to opaque towards the middle most containing a wide variety of inclusions. 

 

Please be attentive if your intention is to acquire fine gem quality rough, you should be prepared to pay much much more per carat. Our moderately accessible collection grade material may yield millimeter size commercial or an occasional “gemmy” carat stone. This would be determined only at the time of individual examination and cutting after purchase. 

 

Therefore, most of our specimens are not being offered to yield fine cut gems, but as a unique and rare collector’s grade mineral demonstrating the classical multiple cyclic twinning in radiating pattern, many occurring encrusted in mica-schist matrix. 

 

Therefore: 

WE WANT TO MAKE VERY CLEAR, WE CAN NOT HONOR RETURNS IF YOU PURCHASE THIS ALEXANDRITE ROUGH EXPECTING A YIELD OF FINE QUALITY GEMS.
