THE NEW RUBELLITE. 



"We -have just received a second and larger lot of Rubellite from the newly 

 opened locality in San Diego Co., California. In the latter part of March we re- 

 ceived fifty pounds of this beautiful variety of Tourmaline and within ten days we 

 sold all but three specimens. More than a week's hard work on the part of our 

 collector is represented in the large consignment which has just arrived and we 

 are informed that it embraces all the best specimeus found. Two types predomi- 

 nate. Radial aggregates composed of columnar crystals, the radiations averag- 

 ing 2 to 5 inches in diameter, often reaching 7 or S inches. The other form con- 

 sists of single crystals thickly scattered through the matrix. In both cases the 

 crystals are bright and well defined, often terminated and averaging one to three 

 inches in length. ' 



There are many variations of these types but all of them present the same 

 exquisite shade of pink in a setting of pale lilac colored Lepidolite, making won- 

 derfully showy specimens of a most attractive species. 



For museums or the shelf of the private collector we have magnificent groups — 

 a mass of color and brilliant crj^stals, vaiwing in size from 4x6 inches up to 

 12x18 inches. Price, $3.50 to $15.00. The choicest cabinet specimens from 2x2 

 to 4 x 5 inches, 25c. to $3.00. Smaller specimens, 5c. to 25c. 



For this new and beautiful mineral our prices are exceedingly low.
