WEST CORRIDOR 



Gems and Precious Stones 



The West Corridor contains tlie Morgan gem collection. This 

 Gems and valuable series of gems and precious stones was presented 



to the Museum by Mr. J. Pierpont IMorgan, one of the 

 founders and a trustee of the institution. It comprises a 

 representative assemblage of cut and uncut gems, many of the former 

 of remarkable size and some of great purity of color. The installation 

 aims to bring into juxtaposition, the cut and uncut material, the former 

 is arranged around the latter, in the center of the cases, and the visitor 

 may thus observe the brilliancy of effect produced in the natural mineral 

 by skillful artificial treatment (cutting). 



A partial gradation in importance and value is obtained b\' the 

 arrangement of the gems, beginning with Diamond at the extreme south
