Synthetic Gems. 



WHAT THEY VIM-: AND HOW THEY ARE MADE. 



I have just secured a small number of sets of Synthetic geinsof Corundum. 

 Each set comprises a series of cut and rough material with samples of the 

 raw chemical products from which they are made. 



The set consists of fifteen specimens of the rough material and ten 

 specimens of cut gems in the following colors : white, yellow, pink, blue 

 and pigeon blood. Each specimen of the rough material has a gem of the 

 same color. The average total weight of the raw material is 2:57 carats, 

 which usually is sold at 25 cents per carat. The average total weight 

 of the cut gems is 27 carats, usually sold at $1.00 per carat. The total value 

 without box and chemicals is about $166.00. 



I was fortunate enough to secure a small number of these sets at a remark- 

 able low figure and can therefore supply museums, professors and collectors 

 with same for $75.00 less 10 per cent, for the months of August and 

 September. Send for a copy of my five page leaflet describing the manu- 

 facture of these interesting gems. 



The display box is 9^x7)^ inches, plush lined, properly labelled. No 

 complete scientific collection should be without this series. I will be pleased 

 to send a set on approval to anyone on request. 



AN ENUSUAL OPPORTUNITY. 



Having greatjy enlarged my stock of California tourmalines, kunzites, pink 

 beryls; hiddenite, ruby corundum and rutile xls. from North Carolina, also 

 green gem tourmaline crystals from Haddam Neck, Connecticut, I shall 

 make special reductions for the months of August and September on these 

 celebrated gem minerals. I have materially reduced the prices on these 

 gem minerals, which will place them within the reach of all. This is 

 the opportunity for collectors to get a fine series for their collections. 



I will gladly send on approval an assortment for inspection upon request 

 by express prepaid.
