CALIFORNIA TOURMALINES. 



Nearly all of the large lot of California tourmalines mentioned in our May 

 advertisement has been sold, and our customers will be glad to learn that we 

 expect to have another lot on sale by the 1st of August. These magnificent 

 specimens are in great demand, and those of our customers who were not in 

 time to obtain just what they wanted from the last lot would do well to call 

 early, in order to secure a good selection. Most of the crystals are rubellites 

 of beautiful rose-pink color, some of them having brilliant yellowish-green 

 terminations. There are also many fine matrix specimens, while we still 

 have some excellent polished sections. Prices on this lot, as on the previous 

 one, are much lower than have ever before been asked for such fine specimens.
