RECONSTRUCTED RUBIES. 



At the recent meeting of the American Society for the Advancement of 

 Science, these rubies were exhibited as made in a crucible and also in the 

 different raw shapes and cut gems, and attracted more attention from the 

 scientists present than anything else exhibited at this meeting. A number 

 of orders from Washington officials and other scientists have been received 

 since, and almost all have duplicated their orders. 



These rubies are as good as the natural ones, if not better ; are made 

 from the same chemical substance, and have the same hardness and lus- 

 trous color, as a genuine ruby. They have also the true pigeon-blood color. 

 The only difference between a natural one and a reconstructed ruby is, 

 that the natural one comes out of the pocket of a rock, and the recon- 

 structed one comes out of a crucible. Litigation is now going on in the 

 Custom House, to put a larger duty on reconstructed rubies. It is a "great 

 damage to the large gem dealers, who have large quantities of genuine 

 rubies, so they are fighting to put a large duty on the reconstructed 

 rubies also. So if you want to secure one, you can now secure them at a 

 very reasonable price ; but, as soon, as the Custom House raises the tariff, 

 naturally enough, we have to increase the price. We have about 400 on 

 hand, from \ to 3k. and cost from $3 to §5 per carat. 



We can furnish you some, in a rough pear-shape form, ^x-^in. Their 

 weight is from 10 to Hi carat. Priced from So to $8 according to quality.
